nanodac
Recorder/Controller
The nanodac™ recorder/controller offers the ultimate in graphical recording combined with PID control for a box of its size. The compact ¼ DIN panel mount unit offers four high accuracy universal inputs for data recording and PID control. This secure data recording device with accurate control is enhanced by a full colour, ¼ VGA display to bring a crystal clear operator interface to even the smallest of machines.
"We combined our extensive expertise in absolute data security and world class control to bring you the best in recording and control in a space-saving, small box with a superb full color display."

Crystal clear, color display.
The 3.5" TFT display offers incredibly clear visualization of process parameters with a wide selection of configurable views to best suit the application. Views include: Horizontal and vertical trends, Horizontal and vertical bar graphs, Numeric, Alarm panel, Alarm status, and control loops. The unit also provides user wiring from the front of the product for detailed configuration without the need to connect to a PC.
Data Acquisition and Recording.
The nanodac recording functionality utilises the secure strategies and UHH format developed by Eurotherm through years of recording expertise. As well as multiple real-time views and historical review on the product, multiple data archiving strategies are provided utilising the 50MB onboard Flash memory, removable USB and data transfer via FTP to a specified server. The four universal input channels provide high accuracy (suitable for use in Nadcap applications) and 125ms parallel sampling. An additional 30 virtual channels can be utilised to provide maths, counter, slave communications and totaliser functionality within the instrument.
PID Control Loops.
The nanodac instrument can also provide up to three independent control loops (optional). This control functionality utilizes the advanced Eurotherm PID algorithm providing high performance and reliability to your process. Functionality includes one of the best autotune facilities available along with overshoot inhibition (cutbacks); compensation for power fluctuations using power feedforward; linear, fan, oil and water cooling.
Heat Treatment is one of the many processes that often need to vary the setpoint of the control process over a set period of time; this is achieved by using a set-point program. The nanodac offers an optional Dual Programmer supporting up to 100 programs locally, each program supporting 25 segments. The nanodac also provides remote access to a further 100 programs that can be easily retrieved via FTP or USB memory stick.
Easy to use setpoint profiler.

Program Editor
Simple setup of setpoint profiles
- Store, retrieve and download program files
- Unlimited program storage
- Online and offline editing
The setpoint Program Editor within iTools provides a simple method of configuring setpoint profiles and programmable event outputs. Programs can be edited live - online with the controller, or offline - for download after editing or storage of the profile. Storage of profiles is limited only by the amount of disk space available on the PC.
