PR electronics 5115B Ex signal calculator. Redundancy measurement with 2 input signals. Input for RTD, Ohm, TC, mV, mA, and V. Universal supply by AC or DC. 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.
