PR Electronics 2289 Signal Calculator is a multifunctional device designed for various signal processing tasks, including PID control, signal calculation, and signal conditioning. It features an intuitive user interface with a 3-digit display and function keys for easy programming and operation.

Advanced Features

  • User Interface: Programmed via a user interface consisting of a 3-digit display and 3 function keys on the front panel.
  • Versatile Functions: Supports a wide range of functions including manual/automatic control, analog calculation, sample-hold, peak-hold, delay transmission, signal limiting, averaging of noisy signals, slope monitoring, and analog multiplexing.

Applications

  • PID Control: Functions as a PID controller with analog or Pt100 inputs.
  • Signal Calculation: Operates as an analog calculator with scaling functions on both inputs.
  • Signal Conditioning: Includes functions such as sample-hold transmitter, peak-hold transmitter, delay transmitter, signal limiter, and averaging of noisy signals.
  • Signal Monitoring: Monitors signal slopes and functions as an analog multiplexer.

Technical Characteristics

  • Programmable Inputs:
    • Inputs A and B: Programmable to receive current signals in the range 0…20 mA (e.g., 4…20 mA) or voltage signals in the range 0…10 VDC.
    • Input A: Linearized Pt100 with a 3-wire connection.
    • Input B: Analog current/voltage input.
  • Digital Inputs: Jumper selectable for NPN or PNP.
  • Analog Output: Standard current/voltage output of 0/4…20 mA / 0/2…10 VDC.
  • Signal Inversion: Both input signals and the output signal can be inverted for flexibility.
  • Mounting Options:
    • Designed for mounting on a standard 11-pole socket, adaptable for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying.
    • PR 7002 can be mounted as an additional safety catch for system 2200 devices on the relay socket in environments with strong vibrations.

PR Electronics 2289 Signal Calculator is an ideal solution for industries requiring versatile signal processing capabilities. Its advanced features, flexible programming, and robust design make it suitable for a wide range of industrial applications involving signal calculation, control, and conditioning.
