RCMB130 series
The AC/DC sensitive residual current monitoring module monitors electrically earthed power supplies up to 300 V and connected loads up to nominal currents of 32 A for leakage and fault currents. The module is intended for installation in distribution equipment such as PDUs (Power Distribution Units), outlet boxes or multiple socket-outlets and is supplied with DC 12…24 V.
The RCMB131-01 is designed for installation in PDUs and outlet boxes. The module can communicate with a master via an RS-485 interface via Modbus RTU.
The RCMB131-02 is designed for installation in PDUs and outlet boxes. The module outputs the rms value of the residual current via a PWM output, which is read out and evaluated by a higher-level circuit.
The RCMB132-01 is designed for installation in PDUs and outlet boxes. The module can communicate with a master via an RS-485 interface via Modbus RTU. It is possible to connect several devices in a daisy chain. For this purpose, the RCMB132-01 provides two identical connectors for RS-485 (incl. power supply).
The products of the RCMB13x series are shipped in bulk and come pre-configured. This makes them particularly suitable for serial integration into power distribution systems, machines or the like by the respective manufacturers (OEMs).
