What is the B&R X20SA4430?

2 safe analog input pairs for current measurement 0.5 to 25 mA

24-bit digital converter resolution

Channels individually galvanically isolated

Sensor power supplies galvanically isolated

Input filter configurable

The module is equipped with 2 safe analog input pairs for current measurement. Each input pair has its own sensor power supply. The channels with their respective sensor supplies are electrically isolated from each other. It can be used to capture current signals in the range from 0.5 to 25 mA.

The safe analog input module is suitable for safely acquiring current signals for safety-related applications up to PL e or SIL 3.

This module is designed for X20 16-pin terminal blocks.
