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

WP-9000 series passive thermal resistance temperature transmitter (output loop power supply) is to isolate and convert the on-site two-wire or three-wire thermal resistance signal into the required DC signal (linear with temperature) and output. Mainly used in DCS and PLC systems with input loop power supply.

　　 This temperature transmitter is a loop power supply mode, and the input loop-the output loop are completely electromagnetically isolated.
