Output Configuration and Load Handling

Each output point uses a separate electromechanical relay. These relays provide true electrical isolation between the PLC and field devices. The GE IC693MDL940H handles resistive loads up to 2 Amps without external suppression. You should add snubber circuits for larger inductive loads. Each relay carries a mechanical life rating of 10 million operations. The electrical life varies from 100,000 to 500,000 cycles depending on the load. The module groups outputs into three commons of four relays each.

Connectivity and Field Wiring

You connect field wiring through a removable terminal strip on the front panel. This terminal strip accepts wire sizes from 0.2 to 2.5 square millimeters. The GE IC693MDL940H features clearly labeled output point numbers and common connections. Each relay includes a visible green LED status indicator. This LED lights up when the output receives an ON command from the CPU. Consequently, you can troubleshoot field wiring without special test equipment. The terminal strip uses screw-type clamps for secure connections.

Installation and Operational Guidelines

You must insert this module into any standard Series 90-30 I/O slot. The backplane supplies 5V DC logic power to the relay coils. The GE IC693MDL940H draws approximately 250 mA from the 5V supply rail. It draws additional current based on how many relays energize simultaneously. The module stores no output states when you remove system power. Therefore, all relays return to their normally open position immediately. You should verify total module current stays below 8 Amps. Exceeding this limit may cause overheating and premature relay failure.
