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 two 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. To add a timer to your panel, the associated 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.

Rated 1 out of 5 by from 1/16 DIN On-Off LCD Temperature I will never buy this instrument again. The thermocouple units will not hold a stable temperature. I am seeing drifts of more than 20 deg C. I bought 5 units and they all behave the same way. If I unplug the thermocouple and plug it in again or replace it with another thermocouple I get totally different Temperature readings. If I turn off the power and restore it again I get different readings. I buy many instruments from Omega with no issue but I am very disappointed in this model.

Will this controller read a type K thermocouple at liquid Nitrogen temperature (approximately -200C)? Data sheet suggests it only accepts an input range to -99C, regardless of sensor type.

Asked by: EdEOV
This on/off controller does not have the capability of reading temperatures below -99C.

Can you please provide details on which types of connections this accepts for thermocouples, and input/output wires?

Asked by: tomk
The CN1A-RTD would use a Female wire quick disconnect terminal for 18 to 22 AWG wire.

Is the electrical connection a simple screw terminal?

Asked by: Aadi
Thank you for your inquiry! Yes, the connections will be simple screw terminals but the socket (CN1A-SOCKET) listed under accessories will be needed.
