Carel IR33V7LR20 ERP_040033

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 mili-amp 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 or 115-230Vac and optional transformers are available for powering the low voltage controllers from 110Vac or 230Vac.
