·Provide isolated DC power supply to the transmitter on site, and receive 4-20mA current signal input from the transmitter. After isolation, interference suppression and other processing, the 4-20mA signal is divided into two signal outputs. The first output is 4-20mA, and the second output is 4-20mA or 1-5V.

·DC power supply mode, the first output of the instrument is loop power supply, and the power supply - input - output channels are isolated from each other.

·Standard 35mm DIN rail card installation. The wiring plug terminals for broadcasting can be connected by spring compression.

● Input
