IC695ALG112 | GE Fanuc Isolated Analog Module | 12-Channel

Product Summary

The GE IC695ALG112 is a 12-channel isolated analog input module for PACSystems RX3i Universal Backplanes. Each channel is individually isolated and supports multiple voltage and current ranges. The module uses a 16-bit ADC and provides configurable filtering, scaling, alarms, and diagnostic reporting. It is fully software-configurable and supports hot-swapping.

• Verify CPU firmware version is 5.0 or later.
• Observe isolation and grounding practices to minimize noise.

FAQ

• Does IC695ALG112 support hot-swapping?
  Yes. The module can be inserted or removed from a powered backplane.
• Are all channels isolated?
  Yes. All 12 channels are individually isolated.
• Can the module detect open circuits?
  Yes. Open-circuit detection is supported for voltage and 4–20 mA inputs.
• Is a terminal block included?
  No. Terminal blocks must be ordered separately.
