Order now IC693MDL940 GE Fanuc Relay Output Module
The IC693MDL940 is a versatile and highly reliable 16-Point Relay Output Module manufactured by GE Fanuc specifically for the Series 90-30 PLC platform. This module provides 16 Normally Open (Form A) relay circuits designed for switching both alternating current (AC) and direct current (DC) loads. With a maximum switching capacity of 2 Amps per point, the IC693MDL940 is the ideal solution for directly controlling motor starters, solenoids, indicator lamps, and interposing relays in a wide array of heavy-duty industrial environments. The module isolates the internal logic of the PLC from the harsh electrical noise of the factory floor, ensuring continuous, uninterrupted operation of your automation processes.

Installation Advice for Inductive Loads
When connecting the IC693MDL940 to inductive loads such as solenoid valves or heavy contactor coils, it is absolutely essential to install transient voltage suppression devices. For AC loads, RC snubbers or MOVs (Metal Oxide Varistors) should be placed in parallel with the load. For DC inductive loads, flyback diodes are mandatory. Failure to suppress these voltage spikes will lead to electrical arcing across the internal relay contacts, causing premature mechanical wear, contact welding, and eventual failure of the module.
Troubleshooting and Maintenance Guidelines
The IC693MDL940 features individual LED indicators on the front panel that correspond to the logic state of each output point, making visual troubleshooting highly intuitive. If an LED is illuminated but the field device fails to actuate, technicians should first check the external load power supply fuses and verify the integrity of the terminal block connections. Because relays are electromechanical components, they have a finite lifespan; in high-frequency switching applications, consider monitoring the cycle counts via the PLC logic to schedule predictive replacement before a failure halts production.

Frequently Asked Questions (FAQs)
Q: Are the output points on the IC693MDL940 individually isolated?
A: The 16 points are grouped into four isolated banks of four points each. Points within a bank share a common power connection, but the separate banks are isolated from one another.
Q: Can this module be installed in any slot of the Series 90-30 baseplate?
A: Yes, the IC693MDL940 can be installed in any available I/O slot of a local, expansion, or remote baseplate within the GE Fanuc Series 90-30 system.
