IR33 Universal Electronic Controllers
The IR33 universal electronic controllers replace the IR32 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 12 to 24Vac/dc and optional transformers are available for powering
the controllers from 110Vac or 230Vac.
