    • Direct Access to Set-Point

      • Monitor and control temperaturewith precision using the CN38SSeries controllers. The CN38SSeries offers an innovative solutionfor programming through anergonomic keypad which usesthe technology “Sensitive Touch”.This sensor keyboard guaranteescomplete protection from dustand liquids in every criticalenvironmental situation. Providingon/off control or PID control withAutotune, this controller is thesolution for many applications.The CN38S series offers a softstart feature. This function makes itpossible to eliminate thermal shockand mechanical stress (due todilatation) that a system undergoesduring start up. In other cases theaim is that of slowing down theincrease in temperature in sucha way that this can spread itselfout evenly inside the material,especially when the machine isequipped with ‘stirrers’ that cannotbe started up at room temperature.The CN38S also offers acompressor protection timefeature, where some actuators,compressors, and pumps cannotbe turned off or turned back ontoo quickly for their constructivecharacteristics. To protect theworking life of the device ittherefore becomes essential tobe able to activate a timer thatguarantees the minimum timebetween the switching off of themachine and the following start up.
