ABB B23 212-100 ‘Bronze’ Two-direction Energy Meter, Three Phase, 65 A, 220 to 400 Vac, Class B, Pulse Output, RS485

Advanced compact DIN-rail meter with an easy to read back lighted display. The meter is intended for use in the commercial or residential buildings etc. Three-phase meter for measuring a three-wire or four-wire three-phase network via a direct connection up to a maximum of 65 A. The following values are output on a white backlit display with up to 7 digits: active energy (class 1) and reactive energy (class 2) for import and export, power , currents, voltages (L-L, L-N), frequency, cos phi, power factor and apparent power, both per phase and in total. 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 an output. This 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 meter is calibrated according to MID and approved according to IEC. The installation width is 4 DIN modules.
