Ex signal calculator
5115B
- Redundancy measurement with 2 input signals
- Signal calculator with the four arithmetical operations
- Duplication of the input signal
- Input for RTD, Ohm, TC, mV, mA, and V
- Universal supply by AC or DC
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.
