SIGNAL CALCULATOR
PRetrans 5115
• Redundancy measurement with 2 input signals
• Signal calculator with four arithmetical operations
• Duplication of the input signal
• Input for RTD, Ohm, TC, mV, mA, and V
• Universal AC or DC supply
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 the four arithmetical operations: addition, subtraction,
multiplica tion 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
Technical characteristics:
• Within a few seconds the user can program PR5115 to a selected application
using the configuration program PReset.
• A green front LED that indicates normal operation, sensor error on each sen-
sor, and func tional 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 modules can be
mounted without any distance between neighbouring units, up to 42 modules
can be mounted per metre.

HOW TO DISMANTLE SYSTEM 5000
First, remember to demount the connectors with hazardous voltages.
Picture 1:
Detach the module from the DIN rail
by lifting the bottom lock.
Picture 2:
By lifting the upper lock and pulling
the front plate simultaneously the
PCB can be removed
Switches and jumpers can now be
adjusted.
