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.

The type of probe is selected by configuration parameter.

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)

• Range of models: the best solution can be easily identified, thanks to the vast range of models available.
• PID regulation: as well as classic proportional and proportional + integral control (P, P+I), PID with autotuning or 2 indipendent control loops have been added.
• Installation: all models are supplied with plug-in terminals. The units can be programmed on the keypad, via key, remote control & comtool.
• power supply: all models are available with 12 to 24 Vac/ 12 to 30 Vdc, 24 Vac/dc or 115 to 230 Vac power supply.
• Display: the large display, complete with icons, makes it easy to set the parameters.
• RTC: used to log the alarms and manage the working cycles
