Product details
The WP-9000 series distributor provides isolated power voltage to transmitters on site, and isolates and converts the (4-20) mA signal generated by the transmitter before outputting it to the control system or other unit combination instruments.
This power distribution device requires independent power supply, with electromagnetic isolation between the power supply input circuit output circuit.
◆ Characteristics
