RCMB131-01 Residual current monitoring module
Product description
AC/DC sensitive residual current monitoring module for measuring DC and AC currents up to ±100 mA
The AC/DC sensitive residual current monitoring module monitors electrically earthed power supplies up to 300 V and connected loads up to rated currents of 32 A for leakage and residual currents. The module is designed for installation in distribution equipment such as PDUs (Power Distribution Units), outgoing boxes or multiple sockets and is supplied with DC 12...24 V.
Features and functions:
- All-current sensitive leakage and residual current monitoring for preventive maintenance
- Suitable for PCB mounting
- High resolution for implementing device leakage current monitoring
- Measured value and alarm transmission via Modbus RTU (RS-485)
- 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 connection monitoring of the measuring current transformer
- Integrated test function
- Supply voltage DC 12...24 V
Application:
The RCMB131-01 is designed for installation in PDUs and outgoing circuit boxes. The module
can communicate with a master via an RS-485 interface via Modbus RTU.
Factory setting RMS 30mA, DC 6mA, (setting range 3.5-100mA), DC 6mA (setting range 3.5-100mA).
