GE Fanuc IC694MDL632 PACSystems RX3i Input Module
Configured for discrete field signal acquisition in PACSystems RX3i backplane architectures, the GE Fanuc IC694MDL632 (IC694MDL632 Input Module) provides direct physical/electrical execution. This single-slot module reads 125 VDC positive or negative logic signals across 8 input channels arranged into two isolated groups of four. Operating within an input voltage window from 0 to 150 VDC with a nominal input current draw of 4.5 mA per channel, it converts high-voltage DC field sensor states into low-voltage logic conditions transmitted over the backplane bus while maintaining electrical isolation between field wiring and internal controller logic.

Backplane Integration & Deterministic Control
The IC694MDL632 establishes low-latency signal routing across the RX3i backplane bus, prioritizing backplane bus communication velocity during real-time scan cycles. Its input filter networks attenuate electrical noise and contact bounce, ensuring high signal integrity for downstream processor calculations. Designed with optimal I/O density scaling and total firmware flash compatibility across the RX3i platform, the module executes rapid optical-to-logic conversion to update state tables without overloading backplane power rails.
Frequently Asked Questions
Q: Can the IC694MDL632 process positive and negative logic input wiring configurations?
A: Yes, the input channels are designed for dual polarity, allowing connection to both positive (sinking) and negative (sourcing) 125 VDC field circuits.
Q: How much current does the IC694MDL632 draw from the RX3i internal 5 VDC backplane bus?
A: The module draws 40 mA from the internal 5 VDC backplane supply, with an additional 36 mA required from the external user field supply.
Q: Are the eight input points on the IC694MDL632 individually isolated from each other?
A: The eight input channels are arranged into two distinct groups of four, providing group-to-group isolation rather than point-to-point isolation.
Field Installation Guidelines
- Power Disconnection: De-energize all 125 VDC external field supply sources and rack backplane power before attaching or detaching field wiring terminals.
- Cable Shielding & Grounding: Route high-voltage 125 VDC input conductors in dedicated metal conduits, keeping them well separated from low-voltage communication lines to reduce inductive cross-talk.
- Terminal Block Attachment: Ensure the removable terminal block mechanism engages firmly onto the front connector header, tightening retention screws to prevent contact resistance during high-vibration operation.
