Universal controllers

The "infrared universale" series is a range of instruments for controlling the temperature, pressure and humidity values in the air-conditioning, refrigeration and heating units. They can however also be used in other contexts, as the voltage or current inputs can support various different types of sensors. In addition, the PT100 probes or thermocouples have an operating range up to 800 °C and can comfortably manage common oven or furnace temperature control processes. The wide range of models can satisfy all requirements:

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 °C

• 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).
