I/O modules

Module Overview

The GE IC697MDL753 output module provides 32 discrete sinking outputs for Series 90-70 PLC systems. This high-density unit controls solenoids, pilot lights, and motor starters efficiently. It interfaces directly with field devices through a removable terminal block. System integrators choose this module for space-critical control cabinets.

Output Channel Configuration

The GE IC697MDL753 features 32 independent output channels in a single module. Each channel operates as an open-collector sinking output for 12/24 V DC loads. The outputs group into four isolated banks of eight channels each. You can connect different voltage supplies to each bank independently. This grouping offers flexible power distribution for mixed loads.

Output Ratings and Current Capacity

Each output channel delivers 0.5 amperes continuously at 24 V DC. The module supports 2 amperes per common for bank current capacity. Inrush current handling reaches 2 amperes for 10 milliseconds. Each channel’s maximum off-state leakage stays below 0.1 milliamperes. These specifications suit most industrial actuator and indicator applications.

Protection Features and Diagnostics

The GE IC697MDL753 incorporates short-circuit protection with automatic current limiting. It includes over-temperature shutdown to prevent thermal damage. The module provides open-wire detection for output load monitoring. Overload conditions trigger individual fault LED indicators on the front panel. These diagnostic features reduce troubleshooting time significantly.

Communication with CPU

The module exchanges data through the Series 90-70 backplane bus. The CPU sends output state commands every scan cycle. The module returns diagnostic and status information to the processor. Configuration software automatically assigns I/O addresses during system setup. This seamless integration simplifies system commissioning.

Physical Dimensions and Mounting

The module measures 125 millimeters in width, 140 millimeters in height, and 55 millimeters in depth. The unit weighs 0.45 kilograms for straightforward handling. It slides into any slot of the Series 90-70 Universal Rack. A locking lever secures the module firmly in position.

Power Consumption Requirements

The GE IC697MDL753 draws 300 milliamperes from the 5 V DC backplane supply. Each bank requires an external 12/24 V DC supply for output energization. The external current draw reaches 4 amperes when all 32 outputs activate. Total power dissipation approximates 6 watts at full load. This efficient design reduces cabinet thermal stress.

Field Wiring and Connector Details

A 40-pin removable terminal block accepts all field device connections. The terminals accommodate wire sizes from 0.2 to 1.5 square millimeters. Each output includes a clearly labeled channel number for identification. The connector block features polarized guides for correct insertion. This modular wiring simplifies module replacement.

LED Status Indication

Thirty-two green LEDs indicate the on/off state of each output channel. A single red LED signals any module-level fault condition. A green OK LED confirms proper backplane communication with the CPU. The indicator panel provides clear visual feedback for operators. This display enables rapid fault identification.

Environmental Specifications

The module operates between 0°C and 60°C ambient temperature. It withstands 5% to 95% non-condensing humidity conditions. The unit meets UL 508 and CSA 22.2 industrial safety standards. Its IP20-rated housing protects against accidental contact. The conformal-coated PCB resists moisture and chemical contamination.
