Ex signal calculator5115B

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
• I.S. safety barrier and power supply for 2-wire transmitters.

Technical characteristics

• Within a few seconds the user can program PR5115B to a selected application using the configuration program PReset.
• A green front LED indicates normal operation, sensor error on each sensor, and functional error.
• 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.

Note

• Not suitable for new installations requiring certification to the latest ATEX standards - see ATEX certificate DEMKO 00ATEX128567 and EU Declaration of Conformity for details.
