    Instrument Description The VPLog-i-R AC current sensor, based on a Rogowski coil, that measures AC currents up to 1600A true-rms on a single phase power cable. The sensor has a modbus interface for communication. The sensor has an indication LED. This blinks when modbus communication is ongoing.
  • Page 7: Installation

    Connection to the cable To install the VPLog-i-R sensor, wrap the measurement coil around the single phase power cable (L1, L2, L3 or N). Then click the plug into the clamp. The coil has to make a closed loop around the power cable.

    (E.G DISCONNECT POWER, WEAR SAFETY GLASSES, RUBBER GLOVES AND ADEQUATE CLOTHES, ETC) Power-On/Off The VPLog-i-R sensor has no power on/off switch. Applying power to the sensor starts its internal power-up sequence. Switch the sensor off by removing its power supply. Connection...
  • Page 9 When addressing registers, the command contains the address minus 1, for instance registers 1..3 are addressed as 0..2. The VPLog-i-R also supports the modbus scan protocol. This allows to change the modbus settings and to request extra information from the module.
