GE IC630MDL325: Industrial Input Module Specifications

This input module captures digital signals from field devices. It sends these signals to a PLC processor for logic execution. The GE IC630MDL325 works with pushbuttons, limit switches, and proximity sensors. You can install this unit in Series Six PLC racks.

Technical Parameters Overview

Input Channel Architecture

Furthermore, the GE IC630MDL325 organizes its 32 inputs into two isolated banks. Each bank contains sixteen independent input channels. These channels accept either sinking or sourcing field wiring configurations. An LED indicator shows the status of every input point. Therefore, technicians can diagnose field wiring problems without special tools.

Signal Processing and Noise Rejection

For reliable signal detection, this module applies a 10 ms filter. This filter removes contact bounce from mechanical switches. Meanwhile, three capacitors store 820 µF of total energy. That storage supplies short-term current during logic transitions. Consequently, the GE IC630MDL325 ignores electrical noise from nearby motors. You will see stable input readings even in noisy environments.

Component Layout and Thermal Design

Moreover, 94 discrete components populate a single fiberglass PCB. The board includes optocouplers for each input channel. These optocouplers provide 1500 VAC of electrical isolation. A metal shield covers the analog comparator circuits. That shield prevents electromagnetic interference from affecting threshold detection. The GE IC630MDL325 also features a passive ventilation grill. Warm air escapes through this grill during normal operation.

Bus Interface and System Integration

The rear edge connector interfaces directly with the PLC backplane. This connection carries power and data signals simultaneously. The GE IC630MDL325 draws 350 mA from the 5 VDC supply. A dedicated enable line allows the processor to read all inputs instantly. You can mix this module with other I/O types in the same rack. For example, place output modules beside input modules without conflict.

Installation and Field Wiring Guidelines

You can insert this module into any Series Six I/O slot. A locking lever secures the unit to the rack chassis. For field wiring, use a 32-point terminal block (sold separately). Each input requires two wires for complete circuit connection. Always use 16 AWG to 20 AWG copper conductors. Maintain 50 mm clearance above the module for heat dissipation.
