Description

Product Description

The IC695ALG608 from GE Fanuc / Emerson is a high-resolution analog input module developed for the PACSystems RX3i platform. It supports both single-ended and differential signal acquisition, offering flexibility for a wide range of industrial measurement tasks.

Designed with a 24-bit sigma-delta ADC, this module delivers precise and stable data acquisition, even in electrically noisy environments. All channels are software-configurable, allowing users to select voltage or current inputs, filtering options, and data formats without hardware changes.

Unlike isolated modules, this unit uses a non-isolated architecture, making it suitable for applications where signal references are common and high channel density is required.
