GE Fanuc IC697MDL750 Series 90-70 32-Point 24/48VDC Discrete Output Module

The IC697MDL750 is a 32-point 24/48VDC discrete output module for GE Fanuc Series 90-70 PLCs. Featuring 0.5A per point capacity, group-to-group isolation, and a removable terminal block, it provides high-density, reliable switching for solenoids, motor starters, and pilot lamps.

High-Density Control Architecture

The IC697MDL750 serves as a high-density discrete output solution within the GE Fanuc (now Emerson) Series 90-70 PLC ecosystem. This module provides 32 independent output channels, allowing the controller to manage a vast array of field devices from a single slot. Because the module supports a broad operating voltage range of 20 to 60 VDC, it easily integrates into systems utilizing both 24V and 48V nominal power supplies. This versatility ensures that the module can interface with diverse industrial hardware, ranging from simple pilot lights to complex solenoid valves and motor starters.

Isolation and Electrical Protection

To safeguard the integrity of the control system, the IC697MDL750 utilizes a sophisticated isolation strategy. The module divides its 32 channels into four distinct groups of eight, providing 500 VDC isolation between each group. Furthermore, the unit features a robust 1500 VDC isolation barrier between the field-side circuitry and the backplane logic. This architecture prevents electrical noise or faults in the field from propagating to the central CPU. Furthermore, the module manages high-demand loads by supporting an inrush current of up to 10 Amps for 20 milliseconds, ensuring that inductive loads do not trigger premature failures.

Installation and Field Wiring

The hardware design prioritizes long-term reliability and ease of service through the inclusion of a removable terminal block. This feature allows technicians to pre-wire or replace modules without disturbing the field connections, significantly reducing system downtime. The terminal block accommodates a wide variety of wire gauges, specifically accepting #22 AWG through #14 AWG conductors. Additionally, the module adheres to the VME standard C.1, which guarantees mechanical and electrical compatibility within standardized industrial racks.
