TL inductors produced by HAKEL. Such a created centre is connected to the terminal of insulation monitoring device HIG93, HIG93/L or HIG94. Insulation monitoring devices enable to display the numeric value of the measured insulation resistance, then there are buttons for setting device parameters and signalling LED diodes to display the status of monitored power supply system and of the device. -

Page 12: Communication Protocol
For ISOLGUARD system PC computer or programmable logic controller with RS485 line can be used as a MASTER station. Also, remote monitoring module MDS-D/66 with protection degree IP66 from HAKEL production may be used. This module allows remote displaying of measured values and set parameters and also data transferring to the user’s master system. -
Page 13: Data Transmitted Via Rs485 Bus
Data transmitted via RS485 bus HIG93, HIG93/L, HIG94 devices communicate on the RS485 bus by using the ISOLGUARD communication protocol. This protocol was designed by HAKEL as a universal command system for reading data from insulation monitoring devices of HIG9x series and additional products. -
