AC/DC sensitive residual current monitoring module for measuring AC and DC currents up to ±100 mA

RCMB131-01 AC/DC sensitive residual current monitoring module Device features • AC/DC sensitive leakage and fault current monitoring for preventive maintenance • High resolution for implementing equipment leakage current monitoring • Measured value and alarm transmission via Modbus RTU (RS-485) • 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 Product description The AC/DC sensitive residual current...

Vcc Customer Controller * Terminating resistor 120 Ω must only be set on the last device in the RS-485 bus chain The maximum cable length must be limited to ≤ 10 m. The switching outputs S1 and S2 are for monitoring purposes only and may only be used from a set response differential current set differential response current IΔn ≥ 6mA DC or RMS.
