RI-R44 - 1

IT NETWORKS INSULATION CONTROL 440 VAC LCD DISPLAY, RS485 General Characteristics RI-R44 is a device that allows the insulation monitoring to earth of AC networks up to 440V isolated (IT systems). By applying a DC component measure signal between the insulated line and earth it’s possible to control the insulation resistance by detecting the generated leakage current. Thanks to the LCD display, the device allows the visualization of the instantaneous insulation value. Configurable automatic or manual resetting. It has a TRIP changeover contact configurable normally de-energised or energised. The RI-R44 is also provided with a RS-485 interface with Modbus protocol to consent the integration in supervision systems.. IIII Features INSULATION MONITORING OF IT SYSTEMS UP TP 440 VAC LCD DISPLAY (Alarm or prealarm indicating events) LOW INSULATION LED RI-R44-485 Instantaneous display LCD display that enables quick alarm viewing of the insulation value. Incorporates illuminated status change for instantaneous detection of the status of the installation.
