IC693MDL635 Positive/Negative Logic Input | GE Fanuc Series 90-30

Product Overview

IC693MDL635 is a GE Fanuc Positive/Negative Logic Input Module from the Series 90-30 family. This 16-channel module operates at 125 VDC rated voltage. It accepts input voltages from 0 to 150 VDC, making it suitable for high-voltage discrete field devices.

Technical Specifications

Installation Guide

Mount the module in any Series 90-30 or RX3i system rack. Apply input voltages between 90 and 150 VDC to guarantee an ON state. Keep input voltage below 150 VDC to prevent damage. The module accepts both positive and negative logic field devices. Use the 16 green LEDs for real-time point status monitoring.

Engineering Advantages

The IC693MDL635 handles high-voltage DC inputs up to 150 VDC. The 250 VAC continuous isolation rating protects the backplane from field surges. Each input draws only 1.97 mA, minimizing power consumption. Positive and negative logic support provides wiring flexibility for sensors, switches, and contactors.

FAQs

Q1: What is the difference between positive and negative logic wiring?
A1: Positive logic turns the input ON when the input terminal receives +VDC relative to common. Negative logic turns ON when the common receives +VDC and the input terminal goes to 0V.

Q2: Can this module accept 24 VDC signals?
A2: No. 24 VDC falls below the 90 VDC ON-state threshold. The module requires 90-150 VDC for reliable operation.

Q3: Is this module compatible with Series 90-30 only or also RX3i?
A3: The IC693MDL635 works with both Series 90-30 racks and RX3i system racks using the appropriate adapter.
