Application

  • Power supply and signal isolator for 2-wire transmitters.
  • Signal isolator for analog current / voltage signals.
  • 1 : 1 or signal conversion of analog current / voltage signals.

Technical characteristics

  • The 20 factory-calibrated measurement ranges in the 5104A can be selected by the internal DIP-switches without the need for recalibration. Special measurement ranges can be delivered.
  • PR5104A is based on microprocessor technology for gain and offset. The analog signal is transmitted at a response time of less than 25 ms.
  • Inputs, outputs, and supply are floating and galvanically separated.
  • The output can be connected either as an active current / voltage transmitter or as a 2-wire transmitter.

Mounting / installation

  • Mounted vertically or horizontally on a DIN rail. By way of the 2-channel version up to 84 channels per meter can be mounted.
