must be ordered separately (PR type no. 5910 and 5913). Sensor error detection
is available.
RTD input for Pt100...Pt1000 according to the norm IEC 751 and Ni100...Ni1000
according to the norm DIN 43760.
Automatic cable compensation at a 3- or 4-wire connection. At a 2-wire con-
nection the cable resistance can be entered or measured by the configuration
program and sent to the module which then compensates by the entered cable
resistance. Sensor error detection is available.
Resistance input for resistance measurement with cable compensation as
described under the RTD input. Sensor error detection is available.
The mV input is programmable in the range -150...+150 mV.
Current / voltage input - jumpers in position 2:
The current input is programmable in the range 0...100 mA, for instance 4...20
mA.
The voltage input is programmable in the range 0...250 VDC.
Auxiliary supplies are selected in the configuration program:
Loop transmitter supply > 18 VDC.
Reference voltage of 2.5 VDC, for instance as a supply for potentiometers.

OUTPUT:

The analogue standard current / voltage output is programmable in the range
0...20 mA, for instance 4...20 mA and 0...10 VDC. The output voltage can be
ordered for a maximum of 12 VDC by a special shunt resistance. The output sig-
nal is proportional and linear to the value of the input signal. Special set-ups can
be selected in the configuration program, for instance a customised linearisation,
a reversed output, a limiter according to the selected output span, and selection
of an output value in case of a sensor error. Maximum load on the current output
is 600 Ω. Minimum load on the voltage output is 500 kΩ.
Loop 4...20 mA current output:
By wiring the current signal alternatively, the output works as a loop output. If the
supply voltage for the 5114 disappears, the output current drops to < 4 mA.
Sensor error detection:
The output can be set up at an RTD, thermocouple and linear resistance input to
go to max., to min. or entered value at sensor error detection. If the output is set
to 4...20 mA it is also possible to select NAMUR NE43 Upscale or Downscale.

CONFIGURATION:

The transmitter is configured to the present task by way of a Windows
NT-based PC and PR electronics A/S' communications interface Loop Link 5905.
The transmitter can be configured with or without a connected supply voltage as
the communications interface supplies the necessary voltage to the set-up. The
communications interface is galvanically isolated to protect the PC port RS232.
Communication is 2-way to allow the retrieval of the transmitter set-up into the
PC and to allow the transmission of the PC set-up to the transmitter. For users
who do not wish to do the set-up themselves, the 5114 can be delivered configu-
red according to customer specifications: input type, measurement range, sensor
error detection, and output signal.
