GE IC695ALG508-AA RX3i 8-Channel RTD Analog Input Module

The IC695ALG508-AA provides 8 isolated differential input channels capable of accepting a wide range of RTD sensor types and resistance signals. Each channel can be independently configured, allowing flexible deployment across different process measurement points.

It supports 2-wire, 3-wire, and 4-wire RTD configurations, making it suitable for both new installations and legacy system upgrades. With built-in signal conditioning, linearization, and diagnostics, it reduces the need for external transmitters.

The module is widely used in RX3i control racks where precision temperature monitoring is essential for safe and efficient industrial operations.
