The B21 112-100 AC meter measures single-phase networks via a direct connection for currents up to a maximum of 65 A. The values are displayed on a seven-segment display with up to 7 digits: active energy (Class 1), power, current, voltage (L-N), and frequency. Communication can occur via the integrated RS485 interface (Modbus RTU) or through the infrared interface for connecting a KNX module. The energy meter has a pulse output and is calibrated according to MID as well as approved according to IEC. The installation width is 2 DIN modules.
