GE Fanuc IC697MDL940 Relay Output Module 16 Ch

IC697MDL940 GE Fanuc Series 90-70 Relay Output Module

Product Introduction

The GE Fanuc IC697MDL940 is a versatile relay output module designed for the Series 90-70 programmable logic controller system. It provides sixteen output channels, combining both Form C and Form A contact configurations. This module supports a wide range of operating voltages, including 120/240 VAC and 5/24/125 VDC. Engineers choose the IC697MDL940 when they need to switch AC or DC loads with galvanic isolation. Furthermore, this module includes built-in fuse protection and snubber circuits for reliable operation.

Technical Specifications of the IC697MDL940

The GE Fanuc IC697MDL940 offers comprehensive relay output capabilities. It features eight individually isolated Form C (changeover) relay outputs and eight Form A (normally open) outputs. The Form A outputs are arranged in two groups of four channels each. Each output channel carries a maximum load current of 2.0 A for AC loads (5–265 VAC, 47–63 Hz) and DC loads (5–30 VDC). For higher DC voltages, the current rating is 0.2 A for 31–125 VDC, and 0.2 A for 31–150 VDC on Form A outputs only.

Output Configuration and Contact Types

The IC697MDL940 uses silver alloy contacts with a maximum resistance of 0.2 Ohms. Each relay features a fixed coil and moving armature design. Mechanical contact life reaches 20,000,000 operations, while electrical life at resistive-inductive loads is rated at 1,000,000 operations. Furthermore, each output includes a 3 A fuse for channel protection. A snubber circuit, consisting of a 47 Ohm resistor and 0.015 µF capacitor, suppresses arcing and extends contact life.

AC and DC Load Handling

The GE Fanuc IC697MDL940 handles both AC and DC loads with distinct ratings. For AC loads, the maximum power is 480 VA, and the frequency range is 47–63 Hz. For DC loads, maximum power reaches 60 Watts. The minimum load requirement is 10 mA for reliable contact wetting. Switching frequency is 20 cycles per minute for inductive loads, ensuring adequate cooling between operations. The maximum output leakage is 1 mA at 120 VAC.

Response Time and Protection Features

Response time for both On and Off transitions is a maximum of 10 milliseconds. This speed suits most industrial switching applications. Overcurrent protection is provided by individual 3 A fuses per output channel. Additionally, the snubber circuit reduces voltage spikes when switching inductive loads, protecting both the relay contacts and connected field devices. Isolation voltage between outputs and the backplane is rated at 1500 Volts.

Power Requirements and Physical Specifications

The IC697MDL940 draws 750 mA from the backplane. It occupies a single slot in a Series 90-70 rack. Module width is standard for the platform. For maximum load capacity, the module supports 16 A total per module and 4 A per group for Form A outputs. The Form C outputs are individually isolated, offering maximum flexibility for mixed-voltage applications.

Installation and Integration Guidelines

Installing the GE Fanuc IC697MDL940 follows standard Series 90-70 procedures. First, ensure rack power is off. Then, insert the module into any available I/O slot, securing it with the retaining clips. Connect field wiring to the removable terminal blocks, observing correct polarity and grouping for Form A outputs. For Form C outputs, wire the common, normally open, and normally closed contacts as required. Finally, apply power and verify operation through the module's status indicators.
