GE IC693MDL655F Input Module

The GE IC693MDL655F accepts field signals from switches, sensors, and pushbuttons in control systems. This input module measures 125 mm in height and 25 mm in width. It fits standard Series 90-30 rack slots without any modifications. The unit weighs 0.22 kg, making installation quick and straightforward.

Channel Configuration and Input Flexibility

This input module provides 16 independent input channels on its front panel. The GE IC693MDL655F accepts both positive and negative logic DC signals. Positive logic requires 15V to 30V DC for an on state. Negative logic requires 0V to 5V DC for an on state. You can mix positive and negative inputs across the 16 channels freely.

Input Specifications and Electrical Characteristics

Each input channel draws 7 mA at 24V DC from field devices. The GE IC693MDL655F provides a nominal input voltage of 24V DC. The module includes optocoupler isolation between field and logic circuits. Input response time ranges from 1 ms to 10 ms selectable. LED indicators show the status of all 16 input channels clearly.

Internal Architecture and Component Layout

The module contains two separate circuit boards inside its plastic housing. One board handles input filtering, while the other manages backplane communication. The GE IC693MDL655F includes a 16-position DIP switch for logic selection. A 48-pin edge connector interfaces with the Series 90-30 backplane. The module stores 33 µF of capacitance for power supply filtering only.

Power Requirements and Environmental Tolerance

The GE IC693MDL655F draws 50 mA at 5V DC from the backplane supply. It requires no external 24V DC power for its input circuits. The module operates reliably from 0°C to 60°C ambient temperature. It tolerates humidity levels up to 95 percent without any condensation issues. The unit withstands vibration up to 2g from 10 to 500 Hz.
