BACHMANN AI204/SI 00012245-00 — Analog Input Module

Original price was: ¥6,666.00.Current price is: ¥2,210.00.

The BACHMANN AI204/SI 00012245-00 module functions as a high-performance analog interface between field instrumentation and the control system. It accepts voltage and current signals from field sensors, conditions them through filtering and isolation, and converts them to digital values via high-resolution A/D converters.
Each input channel is electrically isolated to eliminate ground loops and minimize noise interference, ensuring signal integrity even in electrically noisy environments. The module supports deterministic sampling, making it suitable for use in closed-loop control applications where timing and accuracy are critical. Integrated diagnostics monitor channel conditions and report anomalies to the host controller, aiding preventive maintenance.
