Mount Design
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.
