The IC693MDL940C functions as a relay output module within the GE Fanuc Series 90-30 PLC family. This module switches discrete loads through sixteen independent electromechanical relays. Plant engineers use it for motor starters, solenoid valves, and indicator lamps.

Signal Path and Interface Details
The module receives logic commands from the PLC backplane during each scan cycle. Subsequently, it energizes the corresponding relay coil and closes the output contact. Because relays provide true galvanic isolation, field wiring stays independent of logic ground. The IC693MDL940C therefore handles mixed AC and DC loads on one module.
Energy Storage and Power Draw
No internal battery or capacitor stores energy inside this unit. The backplane supplies all coil current, typically 110 mA at 5 Vdc. Consequently, power loss de-energizes every relay and opens all contacts. System designers should therefore plan fail-safe behavior around this default state.
Installation Notes
Operators insert the module into any available Series 90-30 slot. Removable screw terminals speed up field wiring and replacement. Meanwhile, the 1,500 V isolation protects logic circuits from inductive kickback. Always install flyback diodes across DC solenoid loads.
