ir33 universal, 2 universal inputs, 2 D.O.+ 2A.O., buzzer, ir sensor, 24 Vac/Vdc, panel version.

IR33 universale is a series of controllers designed  for controlling the main physical values(temperature, pressure, humidity)-conditioning, refrigeration and heating units. There are two product lines: the first for two temperature probes only (NTC, NTC-HT, PTC, PT1000) and the second for two temperature probes with a wider range (NTC,NTC-HT,PTC, PT100, PT1000, J/K thermocouples with insulated bulb), for pressure and humidity transducers or for general signal transmitters (0-1V, 0-10V, -0.5-1.3V voltage inputs, 0-5V ratiometric inputs or 0-20mA, 4-20mA current inputs). The models also differ according to the type of power supply (115- 230Vac or12-24Vac, 12-30 Vdc for controllers with temperature inputs only and 115-230Vac or 24 Vac/Vdc for controllers with universal inputs) and which based on the model may be one, two or four relays, four PWM outputs for controlling external solid state relays (SSR), one or two relays plus one or two 0-10 Vdc analogue outputs (AO) respectively. The type of control can be set as ON/OFF (proportional) or proportional, integral and derivative (PID)-The range includes models for panel installation (IR33) and for DIN rail mounting (DN33) with IP65. To simplify wiring, all the models are fitted with plug-in terminals.
