2289 Signal Calculator

Brand: PR Electronics

  • Two analog inputs
  • Multiple functions
  • Front-programmable
  • 3-digit LED display
  • Version with a Pt100 input
  • Analog output
Features
  • Programmed via the user interface which consists of a 3-digit display and 3 function keys in the front panel.
  • The A and B inputs can be programmed to receive current signals in the range 0...20 mA (eg. 4...20 mA), or voltage signals in the range 0...10 VDC.
  • Input A is a linearized Pt100 with a 3-wire connection. input B is an analog current / voltage input.
  • Digital inputs are jumper selectable NPN or PNP.
  • Analog standard current / voltage output of 0/4...20 mA / 0/2...10 VDC.
  • Both the input signals and the output signal can be inverted.
  • Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying. In environments with strong vibrations the PR 7002 can be mounted as an additional safety catch for system 2200 devices on the relay socket.
