IR33S0ER00 Carel IR33 On/Off Temperature Controller, 76.2 x 101mm, 115 → 230 V ac Supply Voltage

IR33 Refrigeration Controller_x000D_ 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_x000D_ No programming required_x000D_ 4 pre-loaded configurations_x000D_ NTC & PTC thermistor probe inputs available_x000D_ Various relay output configurations available_x000D_ 16A compressor output_x000D_ Real time clock and HACCP function_x000D_ Infrared receiver and buzzer_x000D_ 115 to 230V AC powered_x000D_ RS-485 serial connection_x000D_ IP65 enclosure_x000D_ Plug-in terminals_x000D_ Front panel mounting system_x000D_ IR33 Smart Refrigeration Controllers
