R/I TRANSMITTER 2202
• Input for Pt100, Ni100 or Ohm
• Sensor cable compensation
• Linearised analogue output
• 24 VDC or universally supplied
• Individual 0 and 100% adjustment
• DIN rail mounting on a standard 11-pole relay socket

APPLICATION:

Electronic temperature measurement with a Pt100...Pt1000 or a Ni100...Ni1000
sensor.  Conversion of a linear resistance change to a standard analogue cur-
rent / voltage signal from e.g. valves or linear movements with attached poten-
tiometer.  As signal simulator via externally mounted 10-turn potentiometer.
Suit able in applications with potentiometers that are not fully utilised as the 0
and 100% adjustments on the front can be adjusted individually without interac-
ting.

TECHNICAL CHARACTERISTICS:

GENERAL:
The unit is built around a microprocessor core with an efficient program operation.
The supply voltage may be ordered to 24 VDC or with a universal supply of
24...230 VAC and 24...250 VDC with galvanic isolation between supply and input /
output ground. The adjust ment range for the 0 and 100% trimmers has a standard
set-up for ±2.5% of span, but the module may be ordered with an adjustment range
of up to ±25%. The sensor connection is always a 3-wire connection with cable
compensation for up to 10  in each wire. If a 2-wire connection is re quested pins
7 and 6 must be short-circuited in the socket (no cable compensation).

INPUT:

Pt100 temperature input according to the norm IEC 751 within the range
-200...+850°C. Ni100 temperature input according to the norm DIN 43760 within
the range -50...+250°C. Linear resistance input within the range 0...10 k.
The measurement range should be specified when placing the order, e.g.
0...150°C. The min. span is 50°C for the RTD input; for linear resistance the
min. span is 30 . The RTD input can be delivered as multiples of the main type
(e.g. Pt100 x 10 = Pt1000). The input can be reversed so that 0% e.g. is 150°C
and 100% is 0°C.

OUTPUT:

Analogue standard current / voltage output of 0/4...20 mA / 0/2...10 VDC. The
output signal is proportional and linear to the value of the temperature or resist-
ance value that influences the input. Special current or voltage signals can be
ordered. The max. load of the current output is 600 The minimum load of the
voltage output is 500 k Also, a number of different sensor error detection meth-
ods are offered, for instance Upscale  23 mA.
