ZS-31Ex1 Intrinsically Safe Network Power Supply And Isolatior
Brand: Aplisens S.A.The ZS-31Ex1 power supply and isolator is a partially intrinsically safe device with an external (input) intrinsically safe circuit.
The ZS-31Ex1 is designed to supply power intrinsically safe transmitters used in a hazardous area, with a 4...20 mA signal in a two-wire transmission, and to transform that signal through a galvanic separation circuit into one of the standard signals used in automatic control.
The supply voltage of the intrinsically safe input circuit of the standard version of the ZS-31Ex1 is 25 V DC. At the customer’s request this voltage can be altered to 16 or 18 V DC.
The output circuit can be connected to any apparatus with a separated supply voltage of < 250 V (from transformer-based network supplies).
Features- Ex-rated intrinsically safe
- Full galvanic separation of circuits (IN-OUT, IN-SUPPLY, OUT-SUPPLY)
- Accuracy 0.1%
- Casing can be mounted on a standard rail (TS35, TS32)
