PR Electronics 2286 Signal Controller is a versatile device designed for PID control, PI step control, and 3-band control with both analog and Pt100 inputs. It features an intuitive user interface with a 3-digit display and function keys for easy programming, making it suitable for various industrial control applications.

Advanced Features

  • User Interface: Programmed via a user interface consisting of a 3-digit display and 3 function keys on the front panel.
  • Flexible Programming: Channels A and B can be freely programmed via the front keys and JP1/JP2 to current (0…20 mA) or voltage (0…10 VDC).

Applications

  • PID Control: Functions as a PID on/off controller with precise setting of regulation parameters XP (proportional band), TI (integrating time), and TD (differentiating time).
  • PI Step Control: Operates as a PI step controller or 3-band controller.
  • Temperature Input: Supports linearized Pt100 temperature input in the range -99…+850°C with a 3-wire connection.
  • Trip Amplifier: Can be used as a trip amplifier with setpoint adjustment through an external current/voltage signal, featuring a neutral zone surrounding the setpoint.

Technical Characteristics

  • Analog Inputs: Channels A and B are programmable to current in the range 0…20 mA or voltage in the range 0…10 VDC.
  • Temperature Input: Accepts linearized Pt100 temperature input from -99 to +850°C with 3-wire connection for high accuracy.
  • Control Functions:
    • PID On/Off Control: Accurate setting of XP, TI, and TD for precise PID control.
    • PI Step and 3-Band Control: Includes PI step control and 3-band control capabilities.
    • Trip Amplifier Functions: Features dl/dt function, comparator, and trip amplifier with external setpoint.
  • Relay Outputs: Equipped with 2 relay outputs with a make contact connected to a common point.
  • PELV/SELV Circuits: Relay outputs can be installed in PELV/SELV circuits for enhanced safety.

Mounting / Installation

  • Standard 11-Pole Socket: 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 Electronics 2286 Signal Controller is an ideal solution for industries requiring precise control and regulation of processes using PID, PI step, and 3-band control methods. Its advanced features, flexible programming, and robust design make it suitable for a wide range of industrial control applications.
