IC697MDL940 | GE Fanuc Series 90-70 16-Channel Relay Output Module

Product Overview

The GE Fanuc IC697MDL940 serves as a high-density relay output solution for the Series 90-70 PLC ecosystem. This module provides 16 distinct outputs, utilizing a hybrid configuration of Form A and Form C contacts to manage diverse switching requirements. Engineers typically deploy this module to interface the PLC logic with external actuators, motor starters, and solenoid valves across both AC and DC power circuits. Despite its "obsolete" status from the OEM, we supply this unit in 100% Brand New condition to maintain your legacy mission-critical systems.

Technical Specifications

Engineering Advantages

• Mixed Contact Versatility: The IC697MDL940 integrates eight individually isolated Form C contacts and eight Form A contacts (organized into two groups). This layout allows you to control different voltage potentials on the same module without risking cross-talk or short circuits.

• High-Inrush Capability: The silver alloy contacts withstand significant inrush currents, making the module ideal for driving inductive loads like large contactors or heavy-duty solenoids that would typically weld standard gold-flashed relays.

• Robust Signal Isolation: With a 1500V isolation rating, the module protects the Series 90-70 backplane from field-side electrical noise and surges, ensuring long-term CPU stability in electrically "noisy" factory environments.

• Seamless Legacy Integration: This module fits directly into any standard IC697 PLC rack. It requires no software overhead beyond standard I/O configuration, allowing for immediate "plug-and-play" replacement in existing Series 90-70 installations.

FAQs

• Does the IC697MDL940 require an external power supply for the relays?

  The module draws 750 mA from the PLC backplane to power the internal relay coils; however, you must provide the field-side power for the actual loads connected to the Form A and Form C contacts.

• What is the primary difference between the Form A and Form C outputs on this board?

  The Form C outputs are "Normally Open/Normally Closed" and are individually isolated, meaning each point has its own common. The Form A outputs are "Normally Open" only and share a common bus within two groups of four.

• How do I handle inductive flyback when switching DC solenoids?

  We recommend installing external suppression (such as a diode for DC or an RC snubber for AC) across the load to extend the lifespan of the silver alloy contacts, especially if your switching frequency approaches the 20 cycles/minute limit.

• Is this unit refurbished?

  No. We provide this IC697MDL940 in 100% Brand New condition, ensuring maximum mechanical life for the relay armatures compared to used or pulled components.
