RCMB13x

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).

Features

  • AC/DC sensitive leakage and fault current monitoring for preventive maintenance
  • Suitable for PCB mounting (only RCMB131-x)
  • High resolution for implementing equipment leakage current monitoring
  • Measured value and alarm transmission via Modbus RTU (RS-485) (only RCMB13x-01)
  • Measurement signal output via PWM output (only RCMB131-02)
  • Frequency range DC…2 kHz
  • Compact design for monitoring nominal loads up to In = 32 A
  • Low load current sensitivity due to fully shielded measuring current transformer
  • Continuous monitoring of the connection to the measuring current transformer
  • Integrated test function
  • Supply voltage DC 12…24 V
