Bachmann CNT204/H Counter Module

Overview

The CNT204/H is a high-performance counter module from Bachmann electronic GmbH. It delivers precise measurement for industrial automation tasks. The module supports both incremental encoder and HTL counter inputs. This flexibility suits a wide range of motion control and counting applications. The CNT204/H provides synchronized inputs, period measurement with 42 ns resolution, and differential measurement between channels. LED status indicators offer clear monitoring for each input channel. The module also monitors all supply voltages for reliable operation.
