GE Fanuc IC695ALG508 PACSystems RX3i RTD Module
The GE Fanuc IC695ALG508, also cataloged as the IC695ALG508 RTD Input Module, operates as a dedicated hardware component for multi-channel temperature signal conditioning within PACSystems RX3i platforms. The module interfaces directly with 2-, 3-, or 4-wire RTD transducers across eight isolated differential channels, converting low-level resistance measurements into 16-bit integer or 32-bit floating-point registers for CPU processing.

Backplane Bus Communication Velocity and Deterministic Networks
The IC695ALG508 seats into the PACSystems RX3i universal backplane, maintaining high backplane bus communication velocity during active scan cycles. The high-speed PCI backplane interface allows simultaneous channel updates across all eight isolated inputs without degrading logic execution speeds or Ethernet network determinism. Onboard flash memory and diagnostic registers execute internal watchdog routines to maintain system firmware compatibility and high I/O density performance across expansive automation nodes.
Frequently Asked Questions
Q: Can an IC695ALG508 module be replaced while the PACSystems RX3i backplane is powered?
A: Yes, the module supports Removal and Insertion Under Power (RIUP), allowing hot-swap replacement without interrupting power or logic execution on adjacent rack slots.
Q: What internal power distribution lines from the backplane nourish the module?
A: The module draws power directly from the RX3i backplane bus rails, consuming 400 mA at 3.3 VDC and 200 mA at 5.1 VDC, resulting in a maximum power dissipation of 2.5 W.
Q: How does channel-to-channel isolation benefit signal integrity on the IC695ALG508?
A: Optical and galvanic isolation barriers between individual channels prevent ground loop noise, stray common-mode voltages, and cross-talk from corrupting temperature conversion data.
Field Installation Guidelines
First, turn off power to the field transducer loops and verify that the module guide rails align with the designated universal rack slot. Next, seat the IC695ALG508 module into the RX3i backplane, pushing firm on the top and bottom lever handles until the board latch mechanism locks securely. Then, wire 2-, 3-, or 4-wire RTD sensors to the terminal block, verifying lead resistance symmetry for 3-wire configurations to maintain accurate lead-wire compensation. Finally, ground all shielded field cables at the cabinet grounding bar and run signal wiring separately from high-voltage motor supply conductors.
