Product Introduction
The GE IC693MDL752 is an 8-point DC Relay Output Module designed for use with the GE Fanuc Series 90-30 Programmable Logic Controller (PLC) system. It features relay contact outputs that allow for control of AC or DC field devices such as solenoids, contactors, and indicators. This module supports negative logic switching configurations, meaning it can be wired to provide a return path (sink) for the current.
Unlike traditional solid-state outputs, the relay outputs of the MDL752 offer high versatility and electrical isolation, making them suitable for applications that require switching of different voltage levels or AC/DC signals on a single module. It is particularly useful where galvanic isolation between the PLC logic and field devices is essential.

Frequently Asked Questions (FAQ)
-
Q: What type of outputs does the IC693MDL752 provide?
A: It uses mechanical relay contacts capable of switching both AC and DC loads. -
Q: What is the maximum load each relay can handle?
A: Each channel supports 2.0 A, and the total module should not exceed 4.0 A. -
Q: What does “negative logic” mean in this context?
A: It means the module uses sinking logic, where current flows from the load into the module. -
Q: Can this module switch 250V AC loads directly?
A: Yes, it is rated up to 250 VAC per channel, within current limits. -
Q: Are the relay outputs isolated from one another?
A: Yes, each output is electrically isolated, allowing control of different voltage sources. -
Q: Can I use inductive loads like relays or solenoids with this module?
A: Yes, but it is recommended to use flyback diodes or suppressors for protection. -
Q: Is the module hot-swappable?
A: No, always power down the system before inserting or removing the module. -
Q: Does this module require an external power supply?
A: No separate power supply is required—power is drawn from the PLC baseplate. -
Q: How are output statuses indicated?
A: Each output has a dedicated LED for visual status monitoring. -
Q: Is the module suitable for safety-critical applications?
A: It can be used in non-safety circuits, but for SIL-rated systems, use certified safety modules.
