PR electronics Signal Calculator 5115A

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 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.
