IR33 Universal Electronic Controllers
The IR33 universal electronic controllers replace the IR3 range, offering
additional features such as auto-tuning PID control and real time clock
for managing working cycles and logging alarms. Temperature only
versions are available with NTC, PTC or PT1000 inputs, whilst the
universal versions can also accept PT100, J and K type thermocouples,
DC Voltage and DC mA inputs.
The controllers feature a simple user interface, two independent control
loops and are housed in a compact panel mounting enclosure. All versions
can be connected to a network for monitoring and programming, using
the optional RS-485 serial interface. The IR33 controllers are powered
from 1 to 4Vac/dc and optional transformers are available for powering
the controllers from 110Vac or 30Vac.

Temperature Probes
A range of NTC, PTC, PT100 and thermocouple temperature probes
are available to suit the IR33 controllers.
Remote Control
The infrared remote control allows access to all the main functions and
configuration parameters for easy set up of all IR33 controllers from a
distance.
Programming Key
All IR33 controllers can be programmed quickly using the optional
programming key, even when not powered, reducing the risk of errors.
