Product Overview
The ABB DP840 is an 8-channel pulse counter and frequency measurement module for ABB S800 I/O and System 800xA platforms.
Each channel can operate as a pulse counter, frequency (speed) measurement input, or digital input (DI).
The module supports NAMUR, 12 V, and 24 V signal levels, making it versatile for flow measurement, speed detection, and event counting in industrial automation.
Advanced self-diagnostics and support for single or redundant applications ensure high system reliability and operational safety.
Compatible with termination units such as TU810V1, TU812V1, TU814V1, TU830V1, and TU833V1, the DP840 integrates seamlessly into System 800xA distributed control applications.
