DST-811NP Passive Signal Isolator

Classification:

Passive Analog Input

DST-811NP thin passive signal isolator without external power supply, get a little energy from the input signal, to achieve signal isolation. It can cooperate with various industrial sensors and field instruments to retrieve parameter signals, isolate transmission and transmission, and meet the needs of users for local monitoring and remote data. This product variety is divided into one in and one out, two in and two out, three in and three out, four in and four 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:

    The input signals are:4-20mA, output signal: 4-20mA, one in and one out, selection: DST-81111NP-IS-27-0
    The input signals are:4-20mA, output signal: 4-20mA, two-in and two-out, selection: DST-81122NP-IS-27 -0/27-0/0
    The input signals are:4-20mA, output signal: 4-20mA, three in and three out, selection: DST-81133NP-IS-27/27/27-0/0/0
    The input signals are:4-20mA, output signal: 4-20mA, four in and four out, selection: DST-81144NP-IS-27/27/27/27-0/0/0/0

    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;
