Product Overview
Used Omega CN76020 PID Auto-Tune Process Controller, Tested Unit with Minor Clip Damage
The Omega CN76020, part of the CN76000 Series, is a 1/16 DIN auto-tune PID process controller designed for precise temperature and process control in industrial and laboratory systems. This individual unit has been tested and verified fully functional, with minor cosmetic exceptions from the demanufacture process.
One of the ears on the plastic retaining clip broke during removal, and the rubber bulkhead gasket is damaged. These do not affect operation or performance, but we’ve adjusted pricing accordingly—see photos for detail.
Product Condition
Used, tested, and fully operational. The controller’s retaining clip has one broken ear, and the bulkhead gasket is cracked. Both issues are cosmetic and do not affect mounting stability or electrical function. Unit powers, configures, and performs as designed.

Frequently Asked Questions
Is the controller fully operational despite the clip and gasket issues?
Yes. The broken retaining clip ear and damaged gasket are cosmetic only. The controller mounts securely and functions correctly.
Can replacement clips or gaskets be sourced?
Yes. Standard 1/16 DIN clips and gaskets are readily available from Omega or third-party suppliers.
What sensor types are compatible?
Supports thermocouple and RTD inputs, configurable through the front panel for your specific process setup.
Does this controller support output control for heaters or alarms?
Yes. It provides relay, voltage pulse, or current output options depending on configuration.
Was the unit tested before listing?
Yes. Basic functionality, display, were inspected.
It’s not flawless, but it’s Omega—still tuned, tested, and ready to run. This CN76020 carries a few scars from disassembly, proof it’s lived in the real world and still delivers the precision it was built for.
