The module is used in IT power installations. It is being installed for switch point heating and it guards heating equipments and rods isolation states.
Switch CM-HIS is used in cooperation with ground fault protection equipments (e.g. HAKEL HIS500).
This solution saves up to 24 ground fault protection equipments and also the considerable amount of money.
CM-HIS is a device, which is used to switch controlled circuits to one ground fault protection equipment for a defined time period. The module is controlled by the digital inputs. When there are input leads connected the test cycle is started. When a fault is detected a digital output is switched on and the controlling cycle is stopped at the failure circuit. CM-HIS is able to switch 7 controlled circuits. One RM-HIS module can expand number of controlled circuits by 6. It is possible to connect up to 3 RM-HIS modules.
