The 2271 is a transmitter/Trip amplifier suitable for PT100/1000, Ni100/1000 or Ohm inputs. The transmitter converts the input into a proportional and linear analogue output in mA or Voltage. The Trip amplifier of the unit can be set to alarm on either increasing or decreasing inputs and at any point in the full range. An LED light on the front panel is lit under alarm conditions. Each unit requires a 24vDC power supply.
Linearised temperature measurement with PT100/PT1000 or Ni100/Ni1000 sensor.
Conversion of linear resistance change to standard analogue current / voltage signal from e.g. valves or linear movements with attached potentiometer.
As trip amplifier with adjustable alarm limit which may be used as an alarm detector or a simple controller.

2271
L: PT100 N: Ni100 R: Ohms
0: Spec. 1: 0-20 mA 2: 4-20 mA 3: 0-5 mA
A: At increase input B: At decrease input
1: Setpoint knob 2: Setpoint notch
By short circuiting pins 3 and 2 the output current will be converted to standard voltage of 0/0.2-1 VDC (JP1 ON) or 0/2-10 VDC (JP2 ON). The voltage signal is available between pin 2 and 1. See the datasheet for more details.
