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

WP-9000 series thermal resistance temperature transmitter (output loop power supply), input the field thermal resistance temperature signal, isolate and convert the linear (4-20) mA signal with the temperature to the control system or other unit combination instruments. Part of the signal receiving equipment has its own 24V power supply. Generally, the output of the temperature transmitter 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 thermal resistance temperature transmitter. The thermal resistance type and range can be configured and set.

　　 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.
