Overview
Isolated safety barrier at detection side: PHD-11TT-88, thermocouple signal input, single input and single output.
The isolated safety barrier can realize the transmission of thermocouple signals (-5-60mV) from dangerous areas in proportion 1:1 to the safe area, and thermocouples can be K, S, E, J, B, T, R, N types.
When ordering, please indicate the specific parameters
*Bus terminal power supply, please see appendix for details.
