Gossen Metrawatt SINEAX Si815-5 DC Signal Isolator, 2 or 3 Channels, Ex/NEx
Signal isolator for electrically isolating the 4 to 20 mA measuring/supply circuit of a measuring transducer with 2-wire connection. The device fulfils two functions simultaneously.
- Electrical isolation between input and output: prevents the formation of parasitic voltages and currents and eliminates grounding problems with interconnected and intermeshed signal lines.
- The input signal corresponds to the output signal: 4 to 20 mA
- Transmits auxiliary power to measuring transducers with 2-wire connection
- simple, low-cost instrumentation - No auxiliary power terminals:
eliminates the need to lay and connect power supply lines. - Suitable for the transmission of the 4 to 20 mA analog signal which is superimposed over a frequency modulated digital signal (FSK compatible)
- allows for interaction with "intelligent" measuring transducers with 2-wire connection which utilize FSK technology and the HART or a company-specific protocol. - Housing: N17 housing for top-hat rail mounting
