Pulse counter to count pulses that are generated by energy counters via reed contacts or passive transistor outputs (open collector) in proportion to the measured energy. The device has 2 single S0 inputs and a third switchable S0 pulse input to record for example double rate meters. It is also possible to collect pulses from any potential-free contact to count for example events up to a frequency of 15 Hz. The pulses generated by the energy counters are recorded by means of a standardized current interface to DIN EN 62053-3. The pulse counter is feeding the pulse generator that works like a passive two-pole with a direct voltage of 24 V and with a current between 10 and 27 mA for the switching state ON (active) and with 0 to 2 mA for the switching state OFF (passive). The input ST+/ST- is a double rate meter input that stores the S0 pulses of a counter in the counter register T1 or T2 depending on the wiring of input SE/SV. Suitable for decentralized mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.
