15
Function
Essential functions of the IRDH375
• A-ISOMETER
®
for IT AC systems with galvanically connected
rectifiers and for IT DC systems (isolated power)
• Extended voltage range via coupling devices
• Automatic adaptation to the existing system leakage capacitance
• AMP
Plus
measuring principle (patent pending)
• Two adjustable response ranges 1 kΩ ... 10 MΩ
• LC display
• Serial interface
• Connection monitoring
• Automatic self-test
IRDH375B
• Memory with real-time clock to store all alarm messages
with date and time stamp
• RS485 interface (BMS protocol) for data exchange
with other Bender devices (RS485 electrically isolated)
• Internal disconnection of the ISOMETER from the system to be
monitored (using a control signal), e.g. if several Isometers
are interconnected
• Analog output 0(4)...20mA (electrically isolated)
Option “W“:
• Improved shock and vibration resistance
For use:
-in ships
-on rolling stock
-and in seismic environment
