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 analogue process signal to two separate analogue 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
• Ex safety barrier and power supply for 2-wire
  transmitters.

Features

• Redundancy measurement with 2 input signals
• Signal calculator with the four arithmetical operations
