Ex i power supply Series 9143 Rev. C

The Series 9143 compact Ex i power supply is used to provide field devices , e.g. 3- or 4-wire transmitters, solenoid valves, light barriers with intrinsically safe power. It delivers a stable output voltage via intrinsically safe outputs. The additional switching input allows the Ex i power supply to be controlled by binary outputs from a PLC or DCS.

  • To provide 3- or 4-wire transmitters, solenoid valves, light barriers etc. with intrinsically safe power
  • Stable, adjustable output voltage
  • Additional switching input for control via binary output
  • International approvals for global use
