Relays have been the traditional building blocks of control since the 1950s. Still in wide use for simple control or power conversion, styles include electro-mechanical general or special purpose relays such as high power or hazardous location styles, as well as solid-state relays.
Electromechanical relay switches are available in square
relay / ice cube relay, plug-in relay, octal relay, power relay,
hazardous location (HAZLOC) relay, latching relay, slim / card
relay, panel mount, socket mount and DIN rail relay styles for use
in a wide range of process control applications.
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.

Digital Counter, Timer, Tachometer: AutomationDirect
offers solid state timers and digital timer relays 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 selling industrial timing relays in
the U.S. since 1970.
AutomationDirect CTT series multi-function devices are
easily configured for operation as digital counters, digital
timers, combination timer-counters, or digital tachometers.
