WP-9000 series distributor

The WP-9000 series distributor is to provide isolated power supply voltage to the transmitter on site, isolate and convert the (4-20) mA signal generated by the transmitter, and then output it to the control system or other unit combination meters.

　　 This distributor needs independent power supply, electromagnetic isolation between power supply-input circuit-output circuit.

◆ Features

● Provide the transmitter with a distribution voltage (16.5～28)V.

　　● Isolate and transmit the transmitter (4～20) mA signal.

　　● (4～20) mA or (1～5) V signal output, or other required DC signals can be selected.

　　● Modular watch movement design, no need for zero and full scale adjustment.

　　● With working power indicator.

　　● Plug and unplug terminal blocks, DIN rail card installation.
