The Almost Free PLC that's so simple, we named it CLICK®.

All PLCs Should be this Flexible and Convenient

CLICK® CPU modules start at $119.00. You get a ton of control for your automation buck.

Use a CLICK CPU as a standalone PLC...

The Basic & Standard CPU's have eight discrete inputs and six discrete outputs built-in. The Analog CPUs have 4 discrete inputs, 4 discrete outputs, as well as 2 each analog inputs and outputs. All these DC powered PLCs are mighty controllers as stand alone units, or you can expand the I/O count with up to 8 modules for up to 142 total I/O points!

CLICK offers flexible power options

With multiple options for main input power, this flexible unit allows you to decide what best fits in your control cabinet. Use your existing 24VDC power supply (if applicable), select one of our low cost CLICK PLC power supplies (based on your system power budget requirements) or select one of AutomationDirect’s rugged Rhino power supplies.

CLICK to save space and time

CLICK modules lock together for easy installation. CLICK is 'rackless', saving valuable panel space by occupying only as much DIN rail length as required for your application. Zip-link modules cut your PLC wiring time down to minutes instead of hours, and can save you hundreds of dollars on terminal blocks and labor.

...expand CLICK for more complex applications

Expanded with 8 I/O Modules
The I/O line-up includes 24 modules to choose from, including both sinking & sourcing 24VDC input & output options, 120VAC input & output modules, and relay modules for those applications requiring a little more power. The most recent additions are a full line of analog modules including Thermocouple and RTD input modules.

Need a matching HMI?

CLICK is a perfect match for C-more Micro, we designed them to work together. Both are an excellent value. And a single, inexpensive cable supplies power and communication.

CLICK plays nicely with others

Two (2) RS-232 communications ports supporting industry standard MODBUS RTU protocol are included on all units. Standard and Analog models also include an RS-485 port for even more connectivity. These ports are suitable for connection to a PC for programming, networking PLCs, C-more/C-more Micro operator interface panels, variable frequency drives, servos, steppers, and any other MODBUS-enabled devices.

It all adds up to the #1 PLC Value in the industry!

The CLICK PLC is annother great product from Koyo Electronics which compliments their already stellar line-up of PLCs. With a starting price of $119.00 for a CPU w/ 8 built-in digital inputs & 6 built-in digital outputs, this stand alone, Micro Brick PLC is by far the most practical PLC for the money.

Get Connected FAST with just a simple CLICK!

NOW with Ethernet!

The CLICK micro brick PLC was already an incredible value but now we've added even more. The new CLICK Ethernet PLC units come with a 10/100 Mbps multipurpose Ethernet port for faster networking and control. Use the built-in Ethernet port to program your system, network your CLICK, or control Ethernet-enabled end devices. Using the Modbus TCP protocol, the new CLICK PLCs will easily integrate into existing networks and provide a simple, cost effective solution for your application.

Run Time Edits

The new Ethernet Basic and Standard PLCs not only allow for faster connections but they also come with more memory. The added memory size gives CLICK the ability, for the first time, to perform run-time edits on live machinery and/or processes. This new feature can greatly reduce unnecessary downtime and is an important addition to an already extremely practical PLC.

AND Faster Execution

Not only did we improve the communication speed with the new Ethernet PLCs but we also made them capable of executing logic 3 to 10 times faster than before. Nowhere else will you find this level of performance at this low of a price!

FREE Software that's Simple to Learn & Easy to Use

We listened to our customers to create a simple, intuitive programming environment. The CLICK PLC Programming Software is based on the C-more & C-more Micro programming environment. We leveraged these two great programming packages developed by Koyo and created the latest in our line of intuitive programming tools, and then made it a FREE download from our website. So you can have free software for your practically free PLC!

But don’t let the $0.00 price tag fool you - you'll find this software to be loaded with options that you would normally expect to pay extra for!

This includes a more intuative instruction set that is easier to use and extremely functional at the same time. We used Decimal Addressing and preassigned MODBUS addresses. We have worked to create one of the best help files of any software in the industry and we strived to provide the user enough options to easily address all phases of programming (learning, coding, commissioning, troubleshooting).

Intuitive Instruction Set

The CLICK software includes a more intuitive instruction set that is easier to use and extremely functional at the same time. We used Decimal Addressing and preassigned MODBUS addresses. We have worked to create one of the best help files of any software in the industry and we strived to provide the user enough options to easily address all phases of programming (learning, coding, commissioning, troubleshooting).

8,000 Program Steps...

CLICK CPU modules can store up to 8,000 steps (instructions) of your ladder logic program in nonvolatile memory. That's more than enough for most CLICK appropriate applications.

...AND On-board Documentation

Don't need all that memory for your ladder program? You can opt to store all the documentation (your comments, tag names, etc.) on-board the CLICK CPU as well. This can be especially useful if you find yourself editing the program with a different programming PC in the future.

Math Made Easy

Check out the spreadsheet style math instruction, just enter a formula (with embedded PLC tags if you wish) and enter a "result tag". Supports all the standard scientific calculator functions. Make it a "one shot" with a simple check box. It really couldn't be any easier.

Programming Flexibility

NO Limits on Subroutines...

The ladder program can be organized into subroutines with no limit on the number of subroutines other than the total available memory.

...PLUS 8 Interrupt Routines

Up to 8 Interrupt routines can also be defined, and can be initiated based on a time interval or via the discrete inputs on the CPU module. Interrupt routines execute immediately, causing the normal PLC scan to be paused. These are great for time-critical operations, especially if the normal scan time of the PLC is high.

Built-in Communications

CLICK CPUs have two or three built-in communications ports. Ethernet ports (when present) are multipurpose, 8 pin RJ45 ports. RS-232 ports are 6-pin RJ12 phone type jacks. Port 3 (when present) is a three wire terminal-block style RS-485 port.

Port 1 (non-Ethernet models) supports the Modbus RTU protocol only and can be used as the programming part. Port 1’s communication parameters are fixed and it is used primarily as the ladder logic programming port. Port 1 can also be used to connect the CPU as a MODBUS RTU protocol slave device.
Port 1 (Ethernet models) is a full-duplex 10/100 Ethernet port that can be used for programming and/or MODBUS TCP communications. (Ethernet port available on all C0-xxxE-x CPU Models)
Port 2 is a general purpose RS-232 port with user configurable communication parameters. Port 2 can be used as a MODBUS RTU master or slave protocol device, or handle ASCII data ‘In’ or ‘Out’.
Port 3 (Standard and Analog models only) is a general purpose port with user configurable communication parameters. Port 3 can be used as a MODBUS RTU master or slave protocol device, or handle ASCII data ‘In’ or ‘Out’.
Port 3 is available on all Standard (C0-x1xx-x) and Analog (C0-x2xx-x) CPU models.

Ports 1 & 2 (serial only) supply 5 VDC, so you can connect our C-more Micro HMI panel without an additional power supply.

Easy Installation

The CLICK PLC system does not require a mounting base or rack, which saves money and space. CLICK uses only as much space as needed for a specific application

The CLICK CPU and I/O modules are connected together via an integrated expansion port on the sides of the modules and sliding locking tabs on the top and bottom of all modules.

Remove the protective cover
CLICK the neighboring modules together
Slide the locking tabs to secure

CLICK mounts on standard 35mm DIN rail, or via slide-out mounting feet.

Expandable up to 142 I/O

A basic CLICK CPU module is a complete PLC system by itself, most have eight input points and six output points built-in, or the system can be expanded with the addition of up to eight I/O modules. A variety of I/O modules are available for flexible and optimal system configuration.

Cut your PLC wiring time down to minutes instead of hours

The ZIPlink wiring system eliminates the normally tedious process of wiring PLC I/O to terminal blocks. Simply plug one end of a ZIPlink pre-wired terminal block cable into your I/O module and the other end into a ZIPlink connector module. It’s that easy. ZIPlink use half the space, at a fraction of the total cost of terminal blocks.

One ZIPlink model works with all CLICK modules

Two ZIPlink Cable styles...

Decimal Memory Addressing

The I/O numbering system is decimal to make it easier to comprehend, assign and count the I/O points and data registers. Many older PLCs use octal numbering schemes which can be confusing, and also lead to common mistakes.

CLICK Physical I/O points are also numbered starting with 1, instead of 0 to make addressing more straightforward.

CLICK automatically assigns MODBUS addresses to all I/O points and memory registers, to make communications faster and easier.

Made by a company you know and trust

Koyo Electronics Industries Co., LTD., parent company of AutomationDirect, is part of the multibillion dollar JTEKT group of companies that primarily provides components to automotive manufacturers such as Toyota. With this type of engineering and manufacturing background, we expected nothing but the best when we began developing the CLICK PLC and Koyo delivered! While development focused on building a reliable product, they also were able to deliver a product that offers the best combination of price, ease of use and features. The price is almost free while the quality and ease of use is almost priceless.
