N20K48 is an advanced and compact 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*.

*: 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.

**: Firmware updated to v1.03 (for orders placed after 11/16/2023)

• 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 ambient temp range for the controller: -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/disabled in its settings on the user end. 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.

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.
