ir33 universal is designed to be the improvement and extension
of the ir32 universal range.
The models available are divided into two families: the first with
temperature inputs only, and consequently suitable for temperature control in HVAC/R applications and/or generic applications that require the use of a thermostat in the range –50T150
°C; the second with universal inputs (NTC, NTC-HT, PTC, PT1000,
PT100, TC J/K, voltage and current).
In addition, ir33 universal incorporates the main functions
(speed-up, cut-off, control on the higher value read by the 2
probes…) of the CAREL FCM range.
ir33 universal is an advanced controller that includes all the features already available in the previous range, adding some new
sophisticated functions such as PID autotuning, two independent control loops, management of the clock and the working
cycles.
The product features an user interface that is simple to use, in
line with the previous version, while at the same time adding
symbols on the display and navigation menus, making the
interface with the product more user-friendly

The models available are suitable for panel installation (IR33*)
and DIN rail assembly (DN33*). Switching power supply, 12 to
24 V, 24 V or 115 to 230 V, 2 digital inputs, 2 analogue inputs, IR
receiver and buzzer as standard, while some versions feature
integrated 0 to 10 Vdc outputs and/or real time clock.
See the table at the end for the complete list of codes and the
cross-reference with the previous ir32 series.
The following sensors can be connected:
temperature only models
• NTC Standard, range –50T90 °C
• NTC-HT, range –40T150 °C
• PTC Standard, range –50T150 °C
• PT1000 Standard, range –50T150 °C
in addition, for the models with universal inputs
• PT1000 Standard, range –199T800 °C
• PT100 Standard, range –199T800 °C
• TC J/K Standard, range –100T999 °C
• Voltage: 0 to 1V, - 0.5 to 1.3V, 0 to 10V, 0 to 5V rat.
• Current: 0 to 20mA, 4 to 20mA.
The type of probe is selected using a configuration parameter.

the large display, complete
with icons, makes it easy to set

all models are supplied with
plug-in terminals. The units can be
programmed on the keypad, via key,
remote control & comtool

all models are available with
12 to 24 Vac/ 12 to 30 Vdc,

Parameter configuration

Connections

ir33 universal is compatible with the new configuration
tool for CAREL parametric controllers, for fast and practical
setup of the application..

Display

ir33 universal is fitted with a display featuring 3 digits
with decimal point, minus sign and icons, making it
easier to read the values and check the operating status.

The use of plug-in terminals simplifies installation and
any maintenance operations on the unit.
According to the range, only the type of input terminal
changes, as illustrated in the photo, while the output
and power supply terminals remain unchanged.
