PR 3103

Description

• Functional highlights

  • Galvanic separation of analog current signals.
  • A competitive choice in terms of both price and technology for galvanic isolation of all signal types to SCADA systems or PLC equipment.
  • High 3-port isolation provides surge suppression that protects the control system from transients and noise and eliminates ground loops.
  • All terminals are over-voltage protected, polarity protected, and short-circuit protected.
  • The device can be mounted in Safe area or in Zone 2 / Division 2 areas and is approved for marine applications.

  Technical highlights

  • Flexible 24 VDC (±30%) supply via power rail or connectors.
  • Factory-calibrated measurement ranges.
  • Fast response time < 7 ms.
  • Excellent signal / noise ratio > 60 dB.
  • High galvanic isolation of 2.5 kVAC.
  • Inputs and outputs are floating and galvanically separated.
  • A green front LED indicates normal operation and malfunction.
  • Wide ambient temperature range: -25…+70°C.

  Mounting / installation

  • The narrow 6.1 mm housing allows up to 163 units per meter.
  • Units can be mounted side by side, horizontally and vertically, without an air gap on a standard DIN rail, even at 70°C ambient temperature.
  • Units can be supplied separately or installed on the PR 9400 power rail.
