The N20K48 Modular Controller brings a new concept of modularity to PID controllers. Traditionally manufacturers of electronic instrumentation have a wide range of controllers. Each model presents different functionalities designed to meet the specific requirements of each installation. However the N20K48 Modular Controller starts with the core unit with the most popular features but provides many expanded capabilities through the addition of plug and play ClickNGo add-on modules. The ClickNGo modules provide features such as analog inputs and outputs, digital inputs and outputs, and RS485 communications. When added to the core unit, the ClickNGo modules are automatically recognized by the controller, which will display the parameters to set the available resources. A dock accessory is used to attach the modules to the controller. All modules have screw terminals for electrical connections.


Core Unit Features
Without the addition of ClickNGo modules, the N20K48 Modular Controller is a complete and autonomous device capable of handling many basic control functions. It capabilities include

• 1 Universal Analog Input Channel
• 1 Voltage Pulse Output Channel *
• 1 Relay Output Channel *
• Ramp and Soak Control
• PID, AutoTune PID and On/Off Control Modes
• Ramp and Soak Control
• Multiple Alarm Modes
• Timer Control
• USB Communications and Wireless Bluetooth Communications

* Expandable with ClickNGo modules


Ramp and Soak
The N20K48 controller allows you to create a set point profile, called Ramp and Soak program. You can set up to 20 different profiles with 9 segments each. You can also create longer profiles of up to 180 segments by linking 2 or more profiles. The figure below shows an example of a ramp and profile.
