SCMD Digital Relay Modules

Our SCMD Digital I/O Modules create a rugged, protective isolation barrier, effective to 4kV between the field and computer system.

These Opto 22 compatible modules are solid state devices that send "on" and "off" electrical signals to and from a computer.

These relay modules are used for switching AC and DC loads such as relays, solenoids, motor starters or indicator lamps.
