WP-9000 series thermocouple temperature transmitter (output loop power supply)

WP-9000 series thermocouple temperature transmitter (output loop power supply), isolates the on-site thermocouple or millivolt signal into a DC signal (4-20) mA, and transmits it to the control system or other unit combination meters.

　　Some signal receiving devices have their own 24V power supply. Generally, the output of temperature transmitters is an active signal, and power conflicts will occur when connected. Using the output loop power supply type will avoid power conflicts and achieve signal isolation.

　　Intelligent thermocouple temperature transmitter. The user can configure and set the thermocouple type and measuring range through the software.

　　 This temperature transmitter has independent power supply mode and output circuit power supply interface requirements, and electromagnetic isolation between power supply-input circuit-output circuit.
