Industrial Control Relays
General purpose industrial control relays are available in solid state relay, power relay, plug-in relay, electromechanical relay, octal relay, ice cube relay, square relay, card relay, latching relay and sealed relay (HAZLOC) styles for use in a wide range of process control applications.

A variety of relay accessories are also available, including: relay sockets, relay removers, protective covers, spare card relays, and metal oxide varistors (MOV) and diode circuits offered as convenient plug-in modules.

Timer Relays/ Digital Timer Relays
AutomationDirect offers solid state timer relays and digital timers from two leaders in the industry: FUJI Electric and Koyo. All timer relays meet UL and CE conformity. Koyo has been selling timer relays for over 30 years. FUJI Electric has been in business since 1923 and has been selling industrial timers in the U.S. since 1970. All FUJI products are produced under ISO9001 and ISO14000 criteria.

Multi-Function Digital Counters, Timers, Tachometers
AutomationDirect CTT series multi-function devices are easily configured for operation as digital counters, digital timers, combination timer-counters or digital tachometers.

Motor Control Relays / Motor Protection Relays
Phase monitoring relays provide protection against premature equipment failure caused by voltage faults on 3-phase systems.
Alternating relays are used in special applications where the optimization of load usage is required by equalizing the run time of two loads.
Pump failure relays are designed to monitor the shaft seals of submersible pumps.

Solid State Relays (SSR) Solid State Relays (SSR)
A solid state relay switch is a control relay with isolated input and output, whose functions are achieved by means of electronic components without the use of moving parts such as those found in electromechanical relays.
These electronic relays are ideal for applications with many contact closures since solid state relay switches offer a greatly extended life compared to electromechanical relays.
