General Electric IC693MDL930 Isolated Relay Output Module

The GE IC693MDL930 is an 8-point Isolated Relay Output Module designed for use with the GE Series 90-30 PLC system. Engineered to offer maximum flexibility and electrical isolation, the module provides eight individually isolated, Form C (normally open and normally closed) relay outputs. It is used for switching AC or DC loads, making it suitable for a wide variety of industrial automation tasks.

Each output on the IC693MDL930 is isolated from the others, which allows the user to connect each output to different voltage levels or ground references. This feature makes the module especially useful in control applications requiring diverse loads and electrical separations. It’s ideal for driving indicators, solenoids, small motors, and other discrete devices.
