GE Fanuc IC693MDL634 Logic Input Module | 8 Point 24 VDC

Product Overview

IC693MDL634 is a GE Fanuc Logic Input Module from the Series 90-30 family. This 8-channel module operates at 24 VDC rated voltage with a 0 to 30 VDC input range. Field and logic side isolation reaches 1500 V for enhanced protection.

Technical Specifications

Installation Guide

Mount the module on DIN rail in the Series 90-30 rack. Apply input voltages between 11.5 and 30 VDC to guarantee an ON state. Keep input voltage below 30 VDC to prevent damage. The short-circuit protection activates automatically during field wiring faults. Monitor the 8 LED indicators for real-time point status.

Engineering Advantages

The IC693MDL634 delivers 1500 V field-to-logic isolation, protecting the PLC backplane from high-voltage transients. Minimum on-state current of 3.2 mA ensures reliable triggering even with degraded field devices. Response time ≤5 ms captures fast discrete events. The short-circuit protective design prevents module damage during installation errors.

FAQs

Q1: What happens if input voltage is between 5 and 11.5 VDC?
A1: Operation is undefined. The module may not reliably detect ON or OFF state. Keep inputs below 5 VDC for OFF and above 11.5 VDC for ON.

Q2: Can this module accept 12 VDC signals?
A2: Yes. 12 VDC exceeds the 11.5 VDC on-state threshold. However, 24 VDC is recommended for reliable operation.

Q3: Does the short circuit protection auto-reset?
A3: Yes. The module resumes normal operation once the short circuit condition is removed. No manual reset is required.
