ABB S800 I/O Module 3BSE028926R1 Digital Output Module DP840 NEW IN BOX 24V
Description of DP840
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.
