Description
Product Description
The IC695ALG112 is a high-precision 12-channel isolated analog input module designed for the PACSystems RX3i platform. Each channel is independently isolated, allowing safe and reliable measurement of mixed voltage and current signals in demanding industrial environments.
This module supports configurable voltage and current ranges, per-channel diagnostics, open-circuit detection, and multiple alarm settings. Its hot-swap capability allows installation or removal without shutting down the backplane, minimizing downtime. The IC695ALG112 is ideal for process plants, utilities, OEM machinery, and distributed I/O systems requiring high-integrity analog data acquisition.
