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.

The ABB DP840 is an 8-channel pulse counter module belonging to the ABB S800 I/O system. It's designed for use with ABB S800 Programmable Logic Controllers (PLCs) and controllers for industrial automation applications. Counts electrical pulses generated by external devices like sensors or encoders. These pulses can represent various process parameters like speed, position, or flow rate. The DP840 converts these pulses into digital signals that the PLC or controller can understand and utilize for control purposes.
