ABB CBI20 Binary Input Module

Description
The ABB CBI20 is a 32-channel binary input module designed for industrial automation systems, offering galvanic isolation and redundancy capabilities.

Features
Supports signal recording with 1 ms time resolution. Provides central galvanic separation between inputs and system. Features group-set filter time and supports redundant operation. Capable of monitoring various sensor types including contacts and initiators.
