The intrinsically safe ISS2 signal separator is designed to measure the resistance of a temperature sensor installed in a hazardous area. The ISS2 is fitted with two intrinsically safe measurement channels with the protection rating of ia.
On the non-intrinsically safe side, the separator has two analogue outputs, 010 V or 420 mA respectively. The separator can also be accessed remotely to read measurement and configuration data via Modbus protocol in the RTU mode using the physical interface RS-485 and two digital outputs.
The intrinsically safe signal separator ISS2 is fitted the enclosure type ME-MAX 22.5 that provides IP20 protection. The enclosure is designed for installation on the TS35 rail.
The intrinsically safe signal separator type ISS2 as an accompanying device is intended for installation in a main compartment of mining equipment, underground in mines in hazardous areas at risk of methane and/or coal dust explosion and in hazardous areas at risk of gas explosion. The device has transmission channels with the protection rating of ia, which can be used in hazardous areas without having to be disabled in the event of an increase in methane concentration above the permissible limits.
