Application

  • Redundancy measurement of temperature by means of two sensors, where the secondary sensor takes over the measurement when a sensor error occurs on the primary sensor.
  • Duplication of the input signal, e.g. from a temperature sensor or an analog process signal to two separate analog outputs.
  • Signal calculator with four arithmetical operations: Addition, subtraction, multiplication and division.
  • Example: Differential measurement:
    (Input 1 * K1) - (Input 2 * K2) + K4
  • Example: Average measurement:
    (Input 1 * 0.5) + (Input 2 * 0.5) + K4
  • Example: Different functions on the outputs:
    Output 1 = input 1 - input 2, and Output 2 = input 1 + input 2
  • Power supply for 2-wire transmitters.

Technical characteristics

  • Within a few seconds the user can program PR5115A to a selected application using the configuration program PReset.
  • A green front LED indicates normal operation, sensor error on each sensor, and functional error.
  • Continuous check of vital stored data for safety reasons.
  • 5-port 3.75 kVAC galvanic isolation.

Mounting / installation

  • Mounted vertically or horizontally on a DIN rail. As the devices can be mounted without any distance between neighboring units, up to 42 devices can be mounted per meter.
