Carel IR33 On-Off Temperature Controller

IR33 Refrigeration Controller

The IR33 smart refrigeration controllers are designed specifically for the refrigeration installer as they enable selection from a range of pre-loaded applications, eliminating the need to program the controller parameters. The controller then just needs to be wired up and installed in the panel. The controllers have up to 3 NTC or PTC inputs and versions are available which have 1, 2, 3 or 4 relay outputs for control of the compressor, active defrost, evaporator ventilation fan and auxiliary output. The 4 relay version also incorporates a real time clock and HACCP function. The controllers are housed in a compact panel mounting enclosure and are powered from 115 to 230V AC. All versions can be connected to a network for monitoring and programming using the optional RS-485 serial interface
