Universal Input Isolation Smart Temperature Transmitter
WNK65 is suitable for four types of thermal resistors including Cu50, Cu100, PT100, PT1000 and eight types of thermocouple including E, J, B, K, N, R, S, T type. And it supports measurement of minivolt signal of -10~100mV and -100~1000mV, and resistive signal of 0~400Ω and 0~4000Ω. Isolation voltage is DC1000V.
