Dual Loop Controller/Programmer

The RE19 dual loop controller/programmer is destined to control temperature or other physical quantities, e.g. pressure, humidity, level, converted into an electric signal. It can independently control two objects or two physical quantities in one object, e.g. in two-zone furnaces.

This controller is available in three versions:

  • RE19 S for standard (fixed set point) control,
  • RE19 P for standard control or programmed control
    – 15 programs with 15 segments in each program,
  • RE19 V for standard control by motorised valve control
    – at choice, 2 algorithms of stepper control, with or without feedback.

The controller can be equipped with the RS-485 interface with MODBUS protocol.

Description

  • 2 universal analog measuring inputs which accept standard thermocouples, resistance thermometers, linear currents and voltages,
  • 3 displays, which the controlled value, set value, control signal, control deviation and other information concerning the chosen channel are displayed on,
  • 2 x 16-character LCD display destined to communicate with the user,
  • 10 signalling diodes serving to inform about the state of outputs,
  • 2 auto-tuning algorythms helping to select PID parameters,
  • RS-485 interfaces with MODBUS protocol giving the possibility to apply the controller in control systems. Kinds of set-points:
  • Control with fixed set-point, programmed: 15 programs with 15 segments in each (in RE19P) 4 outputs:
  • For control: control of heating , cooling or heating-cooling type, of step control to close and open the valve (in RE19V),
  • For alarm: from measured value or from control deviation,
  • For retransmission: to retransmit measured values, set values or control deviations,
  • For signalling: to signal sensor damages or logic input states Logic inputs:
  • 2 configured inputs by the user,
  • Remote control of the controller operation – stoppage and restart of the automatic control,
  • Clearing of the stored alarms,
  • Blocking of parameters changes from the keypad,
  • Switching of set values or PID parameters,
  • Remote control by the programmed control – stoppage and starting the program, jump to the next segment ( in RE19P).
