GE Fanuc IC695ALG626 PACSystems RX3i Analog Input Module
Configured for high-density signal acquisition in PACSystems RX3i platforms, the GE Fanuc IC695ALG626-HC (IC695ALG626 Analog Input Module) provides direct physical/electrical execution. This non-isolated module interfaces with field transmitters across 16 single-ended or 8 differential input channels, digitizing voltage signals from -10 VDC to +10 VDC and current signals from 0 to 20 mA or 4 to 20 mA via an onboard 24-bit ADC. Incorporating HART Version 5.0 protocol support, the unit processes analog loop values and digital secondary variables directly through the RX3i backplane bus.

Deterministic Backplane & HART Loop Execution
The IC695ALG626-HC transfers digitized process variable data directly across the PACSystems RX3i universal backplane bus, enabling deterministic scan performance with user-configurable digital input filtering (8 Hz to 500 Hz). The module manages 4-20 mA HART loop protocol communications without requiring external modems, passing secondary device diagnostics and dynamic variables to the CPU. Software-configurable channel parameters eliminate physical hardware jumpers, while automatic power-up calibration and firmware flash compatibility maintain measurement accuracy and configuration integrity within the RX3i backplane rack.
Frequently Asked Questions
Q: Does the IC695ALG626-HC require physical jumper settings for current or voltage channel selection?
A: No, all channel parameters, including voltage/current input ranges, digital filter settings, and HART communications, are entirely software-configured via Proficy Machine Edition.
Q: What is the open-circuit detection latency for 4-20 mA current loops?
A: The module executes open-circuit detection on 4-20 mA current ranges within a maximum response time of 1 second.
Q: Can HART protocol features be used on voltage input channels?
A: No, HART Version 5.0 digital communication functions strictly on channels configured for the 4-20 mA current loop range.
Field Installation Guidelines
- Terminal Block Assembly: Use compatible RX3i terminal blocks (IC694TBB032, IC694TBB132, IC694TBS032, or IC694TBS132). Ensure the module is de-energized before latching the terminal block into position.
- Shield Grounding Practices: Terminate field signal cable shields to the designated ground bar on the RX3i rack baseplate using low-impedance connections. Ground shields at one end only to prevent ground loop interference.
- Current Loop Resistors: When wiring current loops, observe the 249 Ohm internal precision resistor load. Ensure total loop impedance does not cause thermal derating under maximum ambient operating temperatures.
