Alstom DIZ 232.1 Digital Counter Module

Product Description

The Alstom DIZ 232.1 is a high-performance digital counter and pulse input module designed for precision accumulation, frequency measurement, and period analysis in industrial automation systems. It interfaces with digital sensors such as flowmeters, rotary encoders, and proximity switches, providing real-time data for position tracking, flow totalization, and process monitoring.

With optically isolated inputs, advanced hardware debouncing, and signal filtering, the DIZ 232.1 ensures reliable and deterministic operation even in electrically noisy environments. Its compact form factor allows integration into Alstom control racks, offloading high-speed pulse processing from the main CPU and maintaining system performance in critical loops.
