ABB DP840 3BSE028926R1 Pulse Counter Module

Overview

The DP840 Pulse Counter module has 8 independent channels. Each channel supports pulse count or frequency (speed) measurement, with a maximum of 20 kHz. The inputs can also be read as digital input (DI) signals. Each channel features a configurable input filter. The module performs cyclic self-diagnostics, including advanced diagnostics for single or redundant applications. It supports NAMUR, 12 V, and 24 V interfaces.
