INTRINSICALLY SAFE POWER SUPPLY AND ISOLATOR - ZS-30Ex1

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 TS35 rail

Application and functions

The ZS-30Ex1 power supply and isolator is a partially intrinsically safe device with an external (input) intrinsically safe circuit.

The ZS-30Ex1 is designed to supply power to 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-30Ex1 is 25 V DC. At the customer’s request this voltage can be altered to 16, 18, 22 or 24 V DC.

The output circuit can be connected to any apparatus with a separated supply voltage of

Calibration

The user can adjust the setting of the start-point and width of the range using potentiometers accessible via marked holes in the front panel.
