                Temperature input isolated barrier, it converts the thermocouple signals from a hazardous area into 1:1mV and 4~20mA signals to a safe area by isolation. It has external cold junction compensation terminals. It needs a backplane power supply. The input, output, and power supply are galvanically isolated from each other. Calibrate the apparatus or modify parameters by using a handheld programmer.

                          Output states
                          Whatever input fault status (except breakage), the output follows the input within measuring range. And the maximum value would not exceed the 110% of the upper limit of the measuring range (e.g. When the output signal type is 0 ~ 20mA, the minimum output value may be 0mA,  the maximum output value would not exceed 22mA)
