ABB Stotz-Kontakt B21 312-100 , B21 312-100 Single phase energy meter, RS485 silver, 1 phase, direct connection 65A , 2CMA100155R1000

AC meter for measuring single-phase networks via a direct connection for currents up to a maximum of 65 A. The following values are output via a seven-segment display with up to 7 digits: active energy (class 1) and reactive energy (class 2) for import and export, power, current, voltage (LN), frequency, cos phi, power factor and apparent power. Communication can take place via the integrated RS485 interface (Modbus RTU) or via the infrared interface for connecting a KNX module. The energy meter has 2 permanently configured inputs and outputs. The output can be used either as a pulse output to output active or reactive energy or as an alarm output. Up to 25 alarm values (threshold values with a time delay) can be set here. The inputs are used to control the tariffs or to count external pulses. The resettable intermediate counter enables individual intervals to be measured. The meter also records up to 4 tariffs. The integrated clock can be used to carry out time-controlled functions. The meter is calibrated according to MID and approved according to IEC. The installation width is 2 DIN modules.
