Rail type isolation distributor

Rail-mounted isolation distributor I have a new statement

Overview Provides isolated power supply voltage to two- and three-wire transmitters. The DC voltage or current signal generated by the transmitter is converted by the isolator to the desired output signal to the control system. It can be used together with the unit combination meter, DCS, PLC and other systems to provide power supply, signal isolation, signal conversion, signal distribution, signal processing, etc. to the on-site primary instrument, thereby improving the anti-interference ability of the automatic control system of the industrial production process and ensuring the system's Stability and reliability. Can display with liquid crystal, touch the button through the infrared switch to display the parameters of different channels, display real-time measurement values, theoretical output values, units and channel numbers.
