The intrinsically safe signal separator type ISS-1 is designed for separation of intrinsically safe signals RS422/RS485/HTL (5V) from non-intrinsically safe signals RS232, RS422, RS485 or HTL (5V). The transmission rate can be changed with the use of a switch from 1.2 kbps to 1.5 Mbps. Termination impedance can be enabled in the same manner.
The intrinsically safe signal separator ISS-1 is fitted the enclosure type ME 22,5 that provides IP20 protection. The enclosure is designed for installation on the TS35 rail. The ISS1 is fitted with a single-channel intrinsically safe serial Interface RS422 or RS485 with protection rating of ia.
The intrinsically safe signal separator type ISS-1 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.
