RTD TRANSMITTER
Programmable via PC
Input for Pt100, Ni100 or Ohm
Linearised analogue output
24 VDC supply
1- or 2-channel version
DIN rail mounting
5102
Application:
Linearised temperature measurement with Pt100 or Ni100
sensor. • Conversion of linear resistance change to standard
analogue current / voltage signal from e.g. valves or linear
movements with attached potentiometer. • Signal simulator
via externally mounted 10-turn potentiometer.
Technical characteristics:
General:
The transmitter may be configured to the requested signal
type by means of a DOS-based PC with the configuration
program PReset 5000 and the communi cations unit Loop
Link. The configuration of the transmitter may be done
without connection of supply voltage as the communications
unit supplies the required power. The supply voltage is 24
VDC with the same reference point for supply, input and
output ground. The sensor connection is always a 3-wire
connection with cable compensation for up to 50 Ω in each
wire. If a 2-wire connection is requested, pins 43 and 42
(channel 1) or 53 and 52 (channel 2) must be short-circuited
in the connection plug (no cable compensation). Sensor
error detection is as standard set to Upscale, Downscale or
entered to special output value.
Input:
Linearised Pt100 temperature input according to IEC
751 within the range -200...+850°C. Linearised Ni100
temperature input according to DIN 43760 within the range
-50...+250°C. Linear resistance input within the range 0...10
kΩ. Min. span for the RTD input is 50°C, for linear resistance
30 Ω. The RTD input can be delivered set up in multiples of
the main type (e.g. Pt1000). The input can be reversed so
that 0% e.g. is 150°C and 100% is 0°C.
Output:
The analogue output may be configured to any current
within the range 0...20 mA or voltage within the range 0...10
VDC with a min. span of 5 mA or 250 mVDC with a max.
offset of 50% of the actual max. value. Voltage signals are
produced by short-circuiting pins 13 and 12 (channel 1)
or 23 and 22 (channel 2) together with mounting a jumper
for internal shunt resistance. For voltage signals within the
range 0...1 VDC a 50 Ω shunt (JP1) is used, within the range
0...10 VDC a 500 Ω shunt (JP2) is used. The voltage signal
is available between pins 12 and 11 (channel 1), or 22 and
21 (channel 2). The min. load resistance for voltage signals
is 500 kΩ.
