Product Description
Blue Jay RCM-IV is a combined monitoring device for earthed power supply systems (TNC-S,TN-S and TT) residual current. It provide max 16 monitor channels, panel mounting design suit for any electrical cabinet. LED screen display various parameters, easy for site engineer diagnosis and Insulation test.
It can optionally be carried out by selected current transformer or temperature sensor for each channel detect parameter and alarm or trip threshold. Multiple RCM-IV can combination with circuit breaker for build MRCD applications, RS485 port can easy submit data to SCADA systems.
- Continuous monitoring of residual currents
- 100 event data recording function, able to record the time of alarm occurrence and fault type
- Standard RS485 communication interface & MODBUS-RTU protocol
- Support manual self-check, optional 2-way passive open input.
- Backlit graphical LED Display
- Up to 16 measuring channels for residual current or temperature input
- The residual current monitoring alarm setting range is 300 ~ 1000mA, with minimal adjustment step 1mA.
- The temperature alarm setting range is 50.0 ~ 100.0C, minimal adjustment step is 0.1°C;
- With 2 relay outputs, free to configure various protection methods.
- Building in buzzer to provide sound alarm, automatically jump to the alarm interface when protection occurs
- Password protection for device setting
- Easy to install, especially for electrical cabinet
