User needs to manually renew this free plan every year. If the same user needs access to more than one controller, he can create a 2nd account with a different e-mail address. Paid plan with additional features are available.
Modbus TCP and MQTT Protocols Supported
By the external WiFi module, N20K48 is compatible with two industry-standard protocols for remote device communication: Modbus TCP and MQTT. Modbus TCP facilitates communication within the confines of the same local area network, whereas MQTT serves as a prevalent protocol for messaging across IoT devices. This dual protocol support enables the controller to seamlessly integrate with a diverse array of data acquisition and SCADA software packages from different manufacturers.
Novus Cloud for Remote Access**
The NOVUS Cloud presents an IoT platform solution tailored for data processing and online visual display. Integrated with the N20K48 and various other Novus smart IoT devices, it serves as an ideal option for clients with limited IT infrastructure or those seeking centralized data from multiple devices across various locations. This Cloud platform efficiently gathers information from IoT devices, securely stores it in a cloud-based database, and showcases the data through sophisticated dashboards. Moreover, it offers the capability to dispatch email notifications in the event of alarm triggers. Hosted on a cloud server, the NOVUS Cloud is globally accessible, enabling users to connect from any internet-enabled computer or mobile device.
**: By the current firmware, you can only read the parameter values & settings through the Novus Cloud via MQTT protocol. But you are unable to change settings via Novus Cloud. This feature will be enabled in the future firmware updates. If you need to remotely change the settings via WiFi, please check AW series WiFi controllers instead.
Original description for N20K48:
N20K48 is an advanced Bluetooth PID temperature controller featuring a vivid LCD display in a modern design package. Evolved from the popular N1050 PID controller, this top-of-the-line product combines the PID algorithm with a larger & brighter multi-color 11-segment LCD display with alphanumeric mnemonics and crystal clear status signaling. With the exclusive Bluetooth feature, users can check/change the settings in this controller via a smartphone app wirelessly. It also has a micro-USB port located on its bottom for temporary wired computer access. It has a built-in timer feature with ramp soak step function*. Please see our comparison table for ramp soak PIDs here.
For the plug-n-play controller with N20K48, please see listing WS-2000F-BT.
*: By default, both the built-in timer function and ramp soak function are disabled by its settings. Users can easily enable either function on the user end by changing settings. For details, see its operation manual.
Features:
- Wide and high contrast, vivid color LCD display with thin frame (compared to N1050)
- Super short profile/low depth 1/16 DIN PID controller (36.7mm depth)
- Wide operation temperature range: -4 to 140°F or -20 to 60°C
- Bluetooth and Micro USB port (computer access**). iOS/Android smartphone Apps and Windows computer software provided.
- A variety of input types, such as thermocouple, RTD and linear mA/V signal (see spec table below)
- Universal output design to drive SSR relay or mechanical contactor
- Ramp soak function* which can be enabled in its settings. 20 ramp soak program profiles, with up to 9 programming steps in every profile. Up to 180 steps when connecting profiles together. Profiles are stored inside of the controller.
- Two timer settings*
- Displays temperature in either Fahrenheit or Celsius
- Modular design for expandability. External ClickNGo modules (not included) can be added to the main control module to achieve external features such as digital input, voltage/analog output, RS485 communication, etc.
Besides the PID auto-tuning capability, N20K48 outputs PWM control mode through SSR output (pulse) or relay. It also features 20 ramp-and-soak profiles (each profile can program up to 9 steps), soft start output and timer function which complement the advanced features of the controller. With password protected, all parameters are configurable by the front keypad, via USB port or Bluetooth.
Easy to install and maintain due to its detachable connector, N20K48 offers the lowest power consumption in the market. Housed in anti-flame material, it has 48x48 mm (DIN 1/16) format and low profile front panel.
**Note for computer access: Bluetooth and USB are both supported by the N20K48 controller. Diagnostics and configuration are accomplished using these connections. Quicktune mobile app (Android & iOS) is provided for wireless Bluetooth connection and Quicktune software (Win only) is provided for USB connection. There is one micro USB port located on the bottom of the controller, closer to the front display. Micro USB method is intended for temporary use only. For details, please see the bottom section on page 34 of its manual. For long time, continuously use like data logging/monitoring, N20K48 with the external RS485 addon module (see combo listing here) or N1050 model B with RS485 interface is recommended.
***Note for USB connection: When you use micro USB cable (not included) to connect this PID controller to your computer, external power supply for this controller is not needed. The power from your computer can also power up this PID controller. This micro USB port is located on the bottom of the controller, closer to the front display. This port will be hidden after this controller is installed to a control panel/box.
