Product Description

The OMEGA CN700 is a digital limit controller from the CN700 series, designed for temperature control with a K-type thermocouple sensor. It operates in limit control mode and features a single 16A SPDT relay output at 250V AC resistive, along with one alarm relay. The unit accepts 110V AC input and includes a digital display, with an operating temperature range of 0°C to 65°C.

Frequently Asked Questions

What is the OMEGA CN700 limit controller used for?

The OMEGA CN700 limit controller is used for over-temperature protection in industrial processes. It monitors a K-type thermocouple and shuts down the system via a 16A SPDT relay if the temperature exceeds a set limit, preventing damage to equipment or materials.

What are the specifications of the OMEGA CN702 limit controller?

The OMEGA CN702 is a digital limit controller with 110V AC input, a 16A SPDT relay output at 250V AC resistive, and one alarm relay. It accepts J, K, or S thermocouple types, operates in limit control mode, and has an ambient range of 0°C to 65°C.

Where to buy the OMEGA CN700 series limit controller worldwide?
