Temperature to RS485 intrinsic safety barrier with signal channel temperature input and multifunctional output, convert the input signals into proportional 4~20mA current signal from hazardous area to safe area.
With affordable intrinsically safe barrier price, it has an alarm setting function, which can be output by relay according to set parameters. The RS485 interface can be connected with rail and the power supply can be connected with rail or terminals.
