Isolator Module

Isolator module. This allows to isolate branch or portion of the loop affected by the short circuit from the rest of the system. Each isolator module can support up to 25 items maximum. This has led blinking in normal conditions or switched on/off in the presence of a short circuit. Unique mechanical design which allows each module to be mounted either in a wall box or on a DIN rail. Irrespective of the mounting method chosen, the address switch is both visible and accessible for selection. To help engineers in the maintenance and fault finding process, both the LEDs and the address switches can be viewed without having to remove the cover of the mounting box. The LEDs, being multi colour, provide diagnostic information regarding the status of the isolator.Power 15-30V DC. Quiescent current of 200 microA. Operating temperature -20°C to +60°C. Relative humidity up to 95%.
