The CN1A Series is a digital on/off temperature controller designed to provide the functionality of general purpose PID controllers but at a price suited to on/off applications. The simple programming with 2 front panel keys, uncluttered LCD display, and uncomplicated control functions and alarm programming have enabled the CN1A to be widely used in a variety of applications. The PTC-1A is designed to combine a harmonized appearance with simple-to-operate, flexible functions and high reliability. 

The CN1A, when combined with the PTC-1A complimentary timer is ideal for frequent user-adjustable applications such as hot foil printing, window sealing and environmental ovens, which often require both temperature and timing control.
