  • Extension device for the HAKEL ISOLGUARD insulation monitoring system.
  • The module allows to complete the control of a (typically hospital) IT system with any signalling using 8 digital inputs and 1 output switching contact.
  • HIG-8IN can be used to monitor, for example, the status of UPS or automatic transfer switches and to read the pressing of alarm or panic buttons.
  • Input statuses sensed by HIG-8IN are signalled to the HAKEL ISOLGUARD MDS-D remote signalling module. HIG-8IN setting is also done via the MDS-D module.
  • RS485 data bus with ISOLGUARD protocol is used for data transfer between HIG-8IN and MDS-D. Up to 10 HIG-8IN modules can be connected to one RS485 bus at a time.
  • HIG-8IN is used in combination with HAKEL ISOLGUARD MDS-D remote signalling modules.
