Product Overview
The GE Fanuc IC693MDL940 provides versatile load-switching capabilities for the Series 90-30 PLC platform. This 100% Brand New original module features 8 independent Relay Output points (Form A, Normally Open) capable of handling both AC and DC voltages. By utilizing mechanical relay contacts, the IC693MDL940 offers superior isolation and the ability to drive higher current loads—up to 2 Amps per point—compared to standard solid-state modules. It serves as the primary interface for controlling motor starters, solenoids, and heavy-duty indicator lamps in industrial automation environments.

Engineering Advantages
-
Universal Voltage Switching: The mechanical relay contacts allow the IC693MDL940 to switch a wide variety of load types, ranging from low-voltage 5V DC signals to high-voltage 240V AC power. This versatility eliminates the need for separate AC and DC output modules in mixed-load applications.
-
High-Ampere Drive Capability: Each channel supports up to 2 Amps of continuous current. This high capacity allows the PLC to drive many industrial actuators and small motors directly, reducing the cost and panel space associated with interposing relays.
-
Superior Electrical Isolation: The physical air gap of the relay contacts provides exceptional galvanic isolation between the PLC backplane and the field circuitry. This barrier prevents high-voltage spikes, surges, or ground faults in the field from compromising the integrity of the CPU or other rack components.
-
Reliable Inductive Load Management: The module handles the back-EMF generated by inductive loads like solenoids and coils more effectively than solid-state alternatives. This ensures stable switching performance even in demanding mechanical environments.
-
Rapid Fault Localization: Eight front-mounted LED indicators provide immediate visual confirmation of the logic state for each relay. Maintenance staff can instantly verify if a control signal reaches the output stage, accelerating the isolation of field-side wiring issues.
FAQs
-
What is the difference between IC693MDL940 and IC693MDL940L?
The "L" suffix typically refers to a specific manufacturing lot or minor hardware revision; however, the IC693MDL940L remains fully compatible and functionally identical to the standard IC693MDL940 within Series 90-30 systems.
-
Do the relays require external power for the coils?
The module draws the power required to energize the relay coils directly from the PLC backplane (+5V bus). However, the "load" power must come from an external AC or DC source connected to the terminal block.
-
Can I use this module for high-frequency switching?
Mechanical relays have a finite lifespan (measured in switching cycles) and slower response times compared to transistors. For high-speed PWM or very frequent switching (several times per minute), consider a solid-state module like the IC693MDL740.
