4-channel pulse counter for counting pulses generated by energy meters via reed contacts or passive transistor outputs (open collector) in relation to the measured energy. Pulses from any potential-free contacts can also be recorded for counting events, for example, up to a frequency of 15 Hz. The pulses generated by energy meters are recorded via a standardized current interface in accordance with DIN EN 62053-31 Class A. The 4-channel pulse counter occupies a factory-set M-Bus address. Suitable for decentralized installation on TH35 mounting rail in accordance with IEC 60715 in electrical distribution boards. Connection with screw terminals
