Description Reviews

The GE Fanuc IC697MDL940 serves as the primary IC697MDL940 Relay output module utilized to execute discrete power switching operations across Series 90-70 platforms. Configured for routing control signals and power switching to external actuator loops, the unit establishes direct physical isolation between internal logic and field-side circuits. The device features a 16-channel array divided into eight individually isolated Form C channels and eight Form A channels segmented into two groups of four outputs.

Backplane Bus Communication Velocity & Control

Operating within the Series 90-70 VME standard architecture, the module execution speed relies directly on the backplane bus communication velocity and physical backplane interrupts. State transition data written from the CPU to the discrete output registers registers instantly at the physical interface. For deterministic networks such as Profinet or EtherNet/IP running via local or remote rack adapters, the response latency is governed by the CPU scan times. Inductive switching limits are physically capped at 20 cycles per minute to minimize contact wear and heat generation, while internal RC snubber networks (47 Ohm resistor paired with a 0.015 ufd capacitor) suppress transient high-voltage spikes.

Frequently Asked Questions

Q: Can the Form C and Form A outputs on the IC697MDL940 be used to switch different voltage phases?

A: Yes. The eight Form C output channels are individually isolated, allowing them to switch different voltages or phases. The Form A channels are divided into two common groups of four and must share a common line voltage within their respective groups.

Q: What action must be taken if a single output channel on the module fails to close?

A: The IC697MDL940 contains internal, non-serviceable 3 A fuses for individual channel protection along with moving-armature contacts. If a short circuit occurs and the fuse blows, or if the silver alloy contacts reach their limit of electrical operations, the physical module must be serviced or replaced.

Field Installation Guidelines

Terminal Alignment: Ensure the field wiring connector block is correctly aligned with the single-slot module guide rails prior to fully seating the terminal assembly.
Inductive Load Suppression: For heavy inductive loads operating near the maximum rating of 2.0 A, external flyback diodes (for DC circuits) or varistors (for AC circuits) are recommended to supplement the internal snubber circuits.
Conductor Routing: Route high-voltage AC load lines separately from low-voltage DC logic wires within the wire duct to prevent high-frequency inductive coupling.
Shielding Termination: Ensure all signal cabling shields are grounded only at one end, typically at the system entry cabinet ground bus, to prevent ground loop currents.
