Déscription
The CN2400 Series are precision PID, self tuning temperature controllers, in 1/4 and 1/8 DIN sizes. They have modular hardware construction with an alarm option, and depending on the model, can accept a wide variety of field installable input, output, and communications modules.The CN2404/08 controllers come with two digital inputs as part of their standard configuration. The control outputs, depending on type, can be configured for either heating, cooling or alarm.| Output Type | Output 1* Order Suffix |
