Precision analog batch recording

The Eurotherm nanodac™-recorder/controller provides four channels of accurate analog batch recording, exceeding regulatory requirements for accuracy and repeatability, and data logging requirements of 21 CFR part 11. For more demanding applications, the Versadac-recorder A back-of-panel solution with almost unlimited capacity. Both enable alarm and discrete input logging, communication with other devices, results available in the data record, electronic signatures, and batch data logging. EtherNET/IP Client- of Server-modus The nanodac recorder/controller is available as an option and can be easily integrated into an existing instrument network and act as a local data historian. When enabled, EtherNet/IP The nanodac can function as either a client or a server and offers data logging for up to 30 process parameters (via virtual channels). EtherNet/IP offers two user pages: the first provides an overview of all process parameters (data points) accessed via communication. The second is a diagnostics page that can be used during initial installation and commissioning to test the connection between the client and/or server.

3 x Isolated DC outputs (DDD)

This release provides support for isolated DC outputs for option slots OP1, OP2, and OP3. Refer to the installation sheet or user manual for wiring instructions.

Washdown front

This release includes an optional, IP66 rated Wash-down-bezel available, making the nanodac suitable for applications in the food and beverage industry or CIP/SIP.

Crystal clear color display

The 3.5-inch TFT screen provides 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 charts;
• Numerical;
• Alarm panel, alarm status and
• control loops.

The device also offers user wiring from the front of the product for detailed configuration without the need for connection to a PC.

Data collection and recording

The nanodac recorder functionality utilizes the safe strategies and UHH format developed by Eurotherm through years of recording expertise. In addition to multiple real-time views and historical product assessments, multiple strategies are used for data archiving provided using the built-in 50 MB Flash memory, removable USB and data transfer via FTP to a specified server. The four universal input channels offer high accuracy (suitable for use in Nadcap applications) and 125 ms parallel sampling. An additional 30 virtual channels can be used to math, counter, slave communication and totalizer functionality within the instrument. Eurotherm Data Reviewer software is the ideal choice for viewing, analyzing and printing historical data files obtained from Eurotherm data acquisition equipment.

PID control loops

The nanodac instrument can also offer two independent control loops (optional). This control functionality utilizes the advanced Eurotherm PID algorithm and offers high performance and reliability for your process. Functionality includes one of the best auto-tune facilities available, along with overshoot inhibition (cutbacks); compensation of power fluctuations through power feedforward; and linear, fan, oil, and water cooling. Heat treatment is one of the many processes that often require varying the control process setpoint over a period of time; this is achieved by setpoint program to use. The nanodac offers an optional Dual Programmer which supports up to 100 programs locally, with each program supporting 25 segments. The nanodac also provides remote access to an additional 100 programs that can be easily retrieved via FTP or USB memory stick.
