2286 Signal Controller

Brand: PR Electronics

  • Multiple functions
  • Programmable from front
  • 3-digit LED display
  • Analog or Pt100 input
  • Relay outputs
  • Max. 50% offset
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 channels can be freely programmed via the front keys and JP1 and JP2 to current in the range 0...20 mA or voltage in the range 0...10 VDC.
  • Linearized Pt100 temperature input in the range -99...+850°C with 3-wire connection.
  • PID on/off controller with accurate setting of the regulation parameters XP (proportional band), TI (integrating time) and TD (differentiating time).
  • Functions include PI step and-band controller, dl/dt function and comparator or trip amplifier with an external setpoint.
  • 2 relay outputs with a make contact connected to a common point.
  • Relay outputs can be installed in PELV/SELV circuits.
  • 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.
