Product Overview

The GE IC693MDL940L is a 16-point discrete relay output module for the Series 90-30 PLC platform. It uses mechanical Form A relay contacts to switch AC and DC loads, providing strong electrical isolation between the PLC backplane and field devices. This makes it suitable for controlling motor starters, solenoids, and indicator devices in industrial automation systems. We supply this unit as 100% brand new, original condition to ensure reliable and long-lasting operation.

Technical Specifications

Engineering Advantages

High-Capacity Load Switching
Each relay supports up to 2 A, enabling direct switching of industrial loads such as contactors and solenoids.

Superior Electrical Isolation
Mechanical contacts provide full galvanic isolation between field wiring and PLC logic, protecting against surges and electrical noise.

Flexible Voltage Compatibility
Each group of outputs can switch independent voltage sources, allowing mixed AC/DC control within the same module.

Instant Diagnostic Feedback
Front-panel LEDs provide real-time output status, enabling quick verification of control signals and field device operation.

FAQs

What does the “L” revision indicate?
It represents a hardware update with improved internal components while maintaining full backward compatibility with earlier revisions.

Does this module require external power for relay operation?
Yes. The module draws logic power from the backplane, but requires 24 VDC at the terminal block to energize the relay coils.

Is it suitable for high-speed switching?
No. Relay switching is typically around 15 ms, so it is not suitable for high-speed or PWM applications.

How can relay life be extended?
Use suppression devices such as RC snubbers (AC) or flyback diodes (DC) when switching inductive loads to reduce arcing and contact wear.
