Universal Input Head Mount Temperature Transmitter With Hart
Protocol
WNK65 head-mount temperature transmitter is universal input type transmitter. It is suitable for four types
of thermal resistors including PT100, PT1000, Cu50, Cu100, eight types of thermocouple including E, J, B, K, N, R, S, T type,
minivolt signal of -10~100mV and -100~1000mV andresistive signal of 0~400Ω and 0~4000Ω. Isolation voltage is DC1000V.
WNK65 temp transmitter has output of 4~20mA and 4~20mA+Hart. And it
supports software calibration with high cost performance.
WNK65 Temperature Transmitter
- Output signal 4-20mA with HART protocol digital communication (
two-wire );

2. Hardware components
2.1 Power
- Supplying power range is DC9V~32V, connected from port 1 and 2.
- Inlay opposite direction voltage protection circuit, misconnetion
of power will cause no damage.
Note: Never connect 24V with sensor port! It will cause permanent damage
of transmitter!
