2202 - R/I TRANSMITTER (11-Pole Socket)

transmitter

» 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...Pt1000or a Ni100...Ni1000 sensor.
» Conversion of a linear resistance change to a standard analogue current / voltage signal    from e.g. valves or linear movements with attached potentiometer.
» As signal simulator via externally mounted 10-turn potentiometer.
» Suitable in applications with potentiometers that are not fully utilised as the 0 and 100%    adjustments on the front can be adjusted individually without interacting.

Technical Characteristics

» 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 adjustment 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 Ω in each wire. If a 2-wire connection is requested, pin 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 kΩ. 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.
