Each independent channel can be individually configured to operate as a pulse counter, frequency or speed input, or standard digital input. The module supports NAMUR, 12 V, and 24 V signal levels, making it adaptable for pulse monitoring and flow measurement applications.\u003c\/p\u003e\n\u003ch3\u003eSignal Processing and Termination Unit Integration\u003c\/h3\u003e\n\u003cp\u003eEach of the eight channels accommodates signal input frequencies up to 20 kHz and utilizes a 16-bit accumulation counter. Input filter response times are configurable on a per-channel basis to suit different sensor characteristics. The DP840 connects to field wiring using compatible S800 module termination units, including the TU810V1, TU812V1, TU814V1, TU830V1, and TU833V1. Built-in cyclic self-diagnostics continuously evaluate hardware status to maintain measurement reliability.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eDP840\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003ePulse Counter \/ Frequency Measurement Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eABB S800 I\/O, System 800xA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Channels\u003c\/td\u003e\n\u003ctd\u003e8 independent channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Operating Modes\u003c\/td\u003e\n\u003ctd\u003ePulse counter, frequency measurement, digital input\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCounter Architecture\u003c\/td\u003e\n\u003ctd\u003e16-bit accumulation counter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Frequency\u003c\/td\u003e\n\u003ctd\u003e20 kHz per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Types\u003c\/td\u003e\n\u003ctd\u003eNAMUR, 12 V, 24 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Filtering\u003c\/td\u003e\n\u003ctd\u003eConfigurable per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRedundancy Support\u003c\/td\u003e\n\u003ctd\u003eSingle or redundant applications\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Termination Units\u003c\/td\u003e\n\u003ctd\u003eTU810V1, TU812V1, TU814V1, TU830V1, TU833V1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e–20 deg C to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e–40 deg C to +85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.7 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eSwitzerland\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What functions can be assigned to the input channels on the DP840?
