refrigeration temperature controller-limiter
ir33 DIN rail (DN33*) is the CAREL proposal for the control of refrigeration units when a solution with DIN rail mounting is required. These devices are completely compatible with the ir33 range in terms of both software and functions. The hardware supplied is very powerful and allows the direct control of up to 2 HP compressors and the management of defrost heaters with 16 A relays. The top-of-the-range version has 5 relays, while all models come as standard with 2 probe inputs and 3 digital inputs (the latter can be configured for probes, if required by the application).
