ABB DP820 3BSE013228R1 Two-Channel Pulse Counting Module

Overview

The DP820 is a versatile two-channel pulse counting module for incremental pulse transmitters, supporting frequencies up to 1.5 MHz. Each channel includes counters and registers for measuring position/length and speed/frequency. It features three balanced inputs per channel for pulse transmitter connection, along with one digital input and one digital output.
