RCMS150 VARYANTLARINI AYIRIN
Six-channel measurement and protocol options.
The RCMS150 series provides six-channel Type B monitoring with RMS and DC evaluation per channel. RCMS150 uses BMS over RS-485; RCMS150-01 uses Modbus RTU. Exact variant selection must match the existing monitoring system’s protocol.
| Measurement coverage | Residual current up to 500 mA, DC…2 kHz |
| Circuit specified in the document | 300 V, 32 A; conductor insulation conditions require separate evaluation at higher voltages |
| Measurement channels | 6 channels; RMS and DC evaluation on each channel |
