Global Innovation In PID Temperature & Process Control
The N20K48 is the latest innovation from Novus Automation for temperature and process control, combining the compact basic form of the N1030 with the advanced display of the N1050 and the high specification of the N1200 series. It offers fast wireless setup via a Bluetooth smartphone app, feature-rich ramp and soak programming (20 programs, 9 segments), a DeepControl advanced self-tuning algorithm, universal input as standard, versatile I/O and communications, all in a compact 1/16 DIN size — big-brand performance and reliability at a highly competitive price, whether bringing an existing process up to the latest specification or starting a new project.
Wireless programming can be carried out with PC, mobile or tablet using the free configuration software and the built-in Bluetooth connection. QuickTune mobile is available on Android and iOS.
Configure your own controller — the N20K48 CPU functions as a standalone PID device with universal input and standard outputs for SSR and relay. The optional docker and ClickNGo modules are added depending on your application. Suitable for ovens, kilns, industrial applications, drying, curing, melting, annealing, autoclaves and more.
What is the difference between a PID Temperature Controller and a PID Process Controller?
A process controller has a universal input and can apply the PID algorithm to a variety of industrial signals — so it's possible to control level, pressure, weight, humidity, and speed, as well as conventional temperature setpoints.

Frequently Asked Questions
Can I configure this without a laptop?
Yes — QuickTune Mobile is available for Android and iOS, and configures the controller directly over Bluetooth.
What do the ClickNGo modules add?
They expand I/O and communications — relay, digital I/O, analogue output, RS485, or WiFi modules clip onto the docker depending on your application. See our N20K48 Docker Interface for the full list of compatible ClickNGo modules.
Is there a 24V version?
Yes, see the N20K48 (12-24V).
Industry Applications
- Ovens, Kilns & Furnaces — 20-program ramp and soak covers demanding multi-stage firing cycles.
- Retrofit & Upgrade Projects — Bluetooth setup makes it fast to bring existing processes to current spec.
- Process Control Beyond Temperature — universal input suits level, pressure, weight, humidity, and speed control.
