Smart 4-20mA Head Mounted Temperature Transmitter with Universal Input
Instruction
WNK621 4~20mA two-wire integrated circuit board is specifically designed for intelligent temperature transmitters. With microprocessor as the core of its highly-integrated circuit, it reliably achieves thermal resistance/thermocouple signal acquisition, processing and loop output, and also provides single bus digital interface and dedicated configurator to achieve full digital debugging and calibrating. it particularly well-suited for producing and manufacturing two-wire intelligent temperature transmitters.
