ABB DP840 3BSE028926R1 Pulse Counter

ABB DP840 3BSE028926R1 Pulse Counter  

Functional Description

The DP840 module consists of 8 identical independent channels. Each channel can be used for pulse count

or frequency (speed) measurement, maximum 20 kHz. The inputs can also be read as DI signals.  Each

channel has a configurable input filter. The module perform self-diagnostics cyclically. With advanced

diagnostics, for single or redundant applications. Interface for NAMUR, 12 V and 24 V. The input can be read

as digital input signals.

Use DP840 with Module Termination Units TU810V1, TU812V1, TU814V1, TU830V1, TU833.
