AutomationDirect adds Optocoupler and Slim Interface Relays, Multi-mode Relay Timers
Murrelektronik optocouplers, slim interface relays and multi-mode relay timers are now available from AutomationDirect. Murrelektronik optocouplers (from $16.50) are used to combine different signal levels or to isolate one signal from another. Optocouplers are similar to relay interfaces, providing an optoelectronic signal transfer between input and output.
