WP-9000 series DC signal converter

The WP-9000 series DC signal converter converts various input DC signals into the required standard process signals through isolation and limited energy processing, and outputs them to the control system or other unit combination meters.

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

◆ Features

　　● DC signal input for field devices.

　　● Standard analog signal electrical isolation.

　　● Linearization conversion output, selectable (4～20)mA or (1～5)V signal and other required DC signals.

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

　　● With working power indicator.

　　● Input circuit overcurrent protection.

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