Designed for pulse-based signals
DP840 is an S800 I/O pulse-counter module built for applications where pulse totals or signal frequency provide useful process feedback. Each of its eight independent channels can be configured for pulse counting or frequency measurement, with a maximum measurement frequency of 20 kHz. The module supports NAMUR, 12 V and 24 V transducer signal levels. Inputs can also be read as digital signals, which can be useful where a project needs pulse-related measurement and a digital status view within the same module family. A configurable input filter is available per channel. Cyclic self-diagnostics and on-board diagnostic functions help identify module or channel conditions, while the module can be used in single or redundant applications where the overall system design supports that arrangement.

MTU compatibility matters
ABB identifies TU810V1, TU812V1, TU814V1, TU830V1 and TU833 among the compatible MTUs. Other compatible MTU variants are also specified; verify the exact installed arrangement before replacement. |

| DP840 | Eight-channel pulse counting, frequency measurement and digital-input reading. | Sensor signal level, counting or frequency task, channel filter and target frequency. |
| DP820 | Another S800 pulse-counter module option for applications requiring a different hardware execution. | Compare exact channel, signal and system requirements before selecting an alternative. |
| TU810V1 / TU812V1 / TU814V1 | Module termination units used as the field-wiring and module interface for compatible S800 I/O configurations. | Check the exact MTU type, keying, wiring arrangement and cabinet configuration; do not select by appearance alone. |
