HRI-R40 - 1

MEDICAL INSULATION MONITORING DEVICE General Characteristics FUNCTIONING PRINCIPLE Insulation resistance is measured by applying a direct current signal between insulated line and earth and determining the dispersion current generated. Effective measurement is granted thanks to a digital filter integrated in the device even if interferences and harmonic components occur. PROGRAMMING Through its LCD display and four selection keys, the device offers easy programming possibilities by setting intervention thresholds without making any mistakes. COMPLETE MONITORING OF ALL ELECTRICAL PARAMETERS HRI-R40 tests the thermal and electrical overload of the medical insulation transformer, managing two temperature thresholds coming from both PT100 and PTC probes. By controlling temperature, the overload of the transformer can be monitored and the automatic circuit-breaker downstream of the secondary can be avoided. All faulty conditions are remotely controlled thanks to PR-5 remote signalling panels, granting a proper prompt technical supervision. SELF-TESTING SYSTEM Error-Link Fail system checks device proper functioning and controls wiring presence and properness at the end of the terminal blocks: it prevents the possibility to operate in group 2 medical locations when the insulation monitoring device is disconnected. THE RECOGNIZED STANDARD IN HOSPITAL INSULATION CONTROL PROPERLY DESIGNED FOR HOSPITALS ALL ELECTRICAL AND THERMAL PARAMETERS CONTROLLED BY A SINGLE DEVICE ADJUSTABLE INTERVENTION THRESHOLDS ACCORDING TO ALL THE PARAMETERS MONITORED ALARMS SENT UP TO 4 MEDICAL LOCATIONS ATTENDED BY MEDICAL AND HEALTHY STAFF, THANKS TO REMOTE SIGNALLING PANELS HIGH RESISTANCE TO NETWORK INTERFERENCES ABLE TO INTERACT WITH SUPERVISING SYSTEMS THROUGH MODBUS RTU PROTOCOL VIA RS485 SERIAL PORT SAFE MONITORING UNDER ANY OPERATIONAL CONDITION, THANKS TO THE CODIFIED SIGNAL FOR HIGHER SAFETY Thanks to a codified signal, the HRI-R40 IT networks insulation monitoring device grants absolute reliability of measurement in any operational condition, even if high network interferences occur. Furthermore it is fitted with a RS485 serial port through which it can be perfectly integrated with communication systems such as PLC/PC by using ModbusRTU protocol. The measurement of network maximum and minimum values enables a wider monitoring and an easier plant checking in case of any fault. Finally, the programmable output relay allows to manage any warning condition signalled in a dedicated way. HRI-R40 measures the insulation to earth in IT-M network and the thermal and electrical overload of the insulation transformer, in accordance with the international standards: EN 61557-8, IEC EN 64-8/7-710 and UNE 20615.
