DST-813 Thin Distribution Current Isolator

Classification:

Power distribution analog input

DST-813 thin distribution current isolator provides isolated power supply voltage for two-wire and three-wire transmitters, and converts the DC current signal generated by the transmitter into the required signal to other instruments through isolation transmission. It can be used with the unit combination instrument and DCS, PLC and other systems to give field instruments signal isolation, signal conversion, signal distribution, signal processing, etc., so as to improve the anti-interference ability of the industrial production process automatic control system and ensure the stability and reliability of the system. This product variety is divided into one in and one out, one in and two out, two in and two out, and the input and output magnetic isolation.

Keywords: Isolator

• Single channel, dual channel This series of varieties have one in and one out, one in and two out, two in and two out, four in and four out. • DC voltage, current, thermal resistance, thermocouple input • Analog output for power distribution • The signal type and test range of some products can be programmed by the supporting PC software • Input/output/power magnetic isolation Transmission accuracy (20 ℃):0.1%FS • Short response time, thin thickness, low power consumption • Plug-in terminals for easy installation and maintenance • Standard 35mm DIN rail clip-on mount

    For example:

    Input signal:0-20mA, output signal: 0-5V, one in and one out. Type selection: DST-81311-IS-25-3-D;

    Input signal:0-20mA, output signal: 0-5V, one in and two out. Type selection: DST-81312-IS-25-3/3-D;

    Input signal:0-20mA, output signal: 0-5V, two in and two out. Selection: DST-81322-IS-25/25-3/3;

    Remarks:Input signal types can only be converted to proportional output signal types. For example, when the input is 4-20mA, the output type can only be 4-20mA or 1-5V. The current output and voltage output cannot be switched. It needs to be completed by changing the hardware. Please indicate clearly when ordering.
