GE IC693MDL241D Input Module for Series 90-30 PLC Systems

The GE IC693MDL241D captures sixteen discrete input signals from field devices. You can install this module directly into any Series 90-30 rack slot. It accepts 24 V DC signals from sensors, pushbuttons, and limit switches. This unit suits factory automation and material handling applications.

Technical Specifications and Hardware Layout

This input module measures 127 mm in height. Its width reaches 55 mm, and the depth equals 140 mm. The GE IC693MDL241D weighs approximately 0.35 kilograms. A single internal PCB holds all input filtering and isolation circuits. The module provides sixteen channels for 24 V DC sinking inputs. It stores no energy in capacitors or internal batteries. One 48-pin front connector handles all field wiring connections. Sixteen green LEDs display the real-time status of each channel.

Input Specifications and Electrical Performance

The GE IC693MDL241D accepts input voltages from 0 V to 30 V DC. It recognizes a logic “1” at 15 V DC or higher. A logic “0” occurs below 5 V DC reliably. Each channel draws a typical input current of 7 mA at 24 V DC. The module filters signal noise with a programmable delay of 0.5 ms to 8 ms. Consequently, you can adapt debouncing for different sensor types. Optical isolation separates the field side from the backplane logic. All sixteen inputs share a single common return terminal for 24 V DC.

Installation and Practical Application Tips

You must snap this module firmly into a standard 90-30 rack slot. Transitioning to wiring, use 0.5 mm² to 1.5 mm² stranded copper wire. The screw-type terminals require a 3 mm flathead screwdriver for tightening. For high-noise environments, use shielded cables for all input signals. The operating temperature range extends from 0°C to 60°C reliably. This module consumes only 50 mA from the backplane bus.
