Crevis – ST-3218 - Rev 1.002 – 8-Channel 4–20 mA Analog Input Module

The Crevis ST- Rev . is an -channel analog input module (– mA), part of the FnIO-S distributed I/O series, compatible with multiple fieldbus protocols via a host adapter. Featuring -bit resolution and a  ms total update rate, it delivers accurate current measurements for industrial control systems and RSTi-like architectures.
