CAREL - ir33 Universal Controllers

The infrared Universale series is a range of instruments for controlling the temperature, pressure and humidity values in air-conditioning, refrigeration and heating units. The range includes models for satisfying all requirements: Models available The models are divided into two families: the first with temperature only inputs, and consequently suitable for temperature control in HVAC/R and/or generic applications that require a thermostat in the range –50T150 °C; the second with universal inputs (NTC, NTC-HT, PTC, PT1000, PT100, TC J/K, voltage and current).

The following sensors can be connected to the “temperature only” models:

  • NTC with range –50T90 °C
  • NTC-HT with range –40T150 °C
  • PTC with range –50T150 °C
  • PT1000 with range –50T150 °C

The following sensors can be connected to the “Multi-in” models:

  • NTC with range –50T90 °
  • NTC-HT with range –40T150 °C
  • PTC with range –50T150 °C
  • PT1000 with range –50T150 °C
  • PT1000 with range –199T800 °C
  • PT100 with range –199T800 °C
  • TC J/K with range –100T800 °C
  • Voltage: 0 to 1 V, -0.5 to 1.3 V, 0 to 10 V, 0 to 5 V rat.
  • Current: 0 to 20 mA, 4 to 20 mA.

Main functions include:

  • PID with autotuning;
  • 2 independent control loops;
  • clock management for logging alarms;
  • work cycles.

Types of outputs: relay, 0 to 10 Vdc, or control of external SSRs
Type of power supply: models are available for mains power supply (115 to 230 Vac), or alternatively operating at 12 to 24 Vac-dc or 24 Vac-dc
Panel or DIN rail mounting: all models are available for both classic panel installation with IP65 front protection, or for DIN rail mounting (4 modules).
Backward compatibility: the list of parameters is compatible with the previous “ir32 Universale” range
Other functions: 2 digital configurable inputs, IR receiver and buzzer available on all models; some versions also feature the real time clock (RTC).

CAREL - Clima Controllers

The new room humidistat with built-in humidity sensor, or remote sensor for applications, is fitted with an LCD with alphanumeric characters and icon graphics for simple use. The 24 Vac supply allows direct connection to the humidifier without the need for additional transformers. The functions that can be selected range from simple thermostat and humidistat with ON/OFF or modulating logic, to the management of temperature and humidity with compensation, using an external sensor. The built-in clock allows the automatic management of an ON and OFF period over a 24h interval. The same function can be managed by an external timer, by the digital input which, alternatively, can be used for the alarm signal from the humidifier. In the hotel type applications, the LOCK terminal function, selectable by parameter is very useful, as it allows the terminal to be locked at various levels.
