Product details
-
Thermal resistance input type safety barrier is a control system or other unit combination instrument that isolates and converts the thermal resistance signal in the hazardous area on site into a linear DC signal with temperature, and outputs it to the safety zone.
Intelligent thermal resistance temperature transmitter that can configure and set the type and range of thermal resistance.
This safety barrier requires independent power supply, with three terminals isolated from input, output, and power supply.
Equipped with a working power indicator light.
Plug and unplug terminal block, DIN rail card installation.
