IC694MDL635 GE Fanuc RX3i 125VDC 16pt Input Module

IC694MDL635 Technical Performance Profile

• The IC694MDL635 is a high-voltage DC input module engineered for the RX3i PacSystem series.
• It provides 16 discrete input points arranged in a single group with a shared common power terminal.
• Operating at a rated 125 Volts DC, the module supports both sink and source (positive/negative) logic configurations.
• Advanced signal filtering ensures a typical response time of 8ms for both On-state and Off-state transitions.
• Safety is prioritized with distinct red color-coding on the module label to signify high-voltage operation.

Global PLC Spare HUB's Insight

• The IC694MDL635 is the primary choice for utility and substation automation within the RX3i environment.
• Its ability to handle up to 150V DC allows for significant overhead in environments with fluctuating battery-backed power systems.
• We emphasize that the IC694MDL635 utilizes a single group of 16 points, which simplifies high-density wiring layouts.
• Engineering teams rely on this module's G-force resistance (15G shock) for deployment in heavy industrial transport or power generation sites.

Professional FAQ & Engineering Guide

• Question: Does the IC694MDL635 require external power to register inputs?
• Answer: Yes, user-supplied power is mandatory to drive the field devices connected to the 16 input points.
• Question: Can I mix positive and negative logic on the same module?
• Answer: No, because all 16 points share a single common terminal, the entire IC694MDL635 must be wired for one logic type.
• Question: What is the significance of the 1.97mA input current?
• Answer: This low current draw allows the module to sense signals without placing a heavy load on sensitive field contacts.
• Question: Is this module compatible with the older Series 90-30 systems?
• Answer: While RX3i supports many 90-30 modules, the IC694MDL635 is specifically optimized for the IC694 high-speed backplane.
• Question: How do I handle vibration in high-impact environments?
• Answer: The module is rated for 1.0G acceleration; ensure the RX3i rack is securely grounded and fastened to a rigid sub-panel.

Strategic Selection & Buying Advice

• Verify that your field voltage does not exceed the 150V DC absolute maximum to prevent internal component stress.
• Consider the 8ms response time when designing high-speed safety interlocks to ensure system timing requirements are met.
• Always check for the red module identifiers on the IC694MDL635 to distinguish it from low-voltage DC modules during installation.
