nanodac™ Recorder / Controller

EtherNET/IP Client or Server mode

Available as an option, the nanodac recorder/controller can be easily integrated with an existing instrument network and act as local data historian. When enabled, EtherNet/IP allows the nanodac to act as either a Client or a Server and provides data recording for up to 30 process parameters (via virtual channels). EtherNet/IP provides two user pages, the first is an overview of all the process parameters (data points) being addressed via the communications. The second is a diagnostics page that can be used during initial setup 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 in option slots OP1, OP2 and OP3. Please refer to the Installation sheet or User Guide for wiring instructions.

Washdown Front

An optional IP66 rated Wash-down bezel has been made available in this release, making the nanodac suitable for applications in Food & Beverage or CIP/SIP.

Crystal clear, colour display

The 3.5” TFT display offers incredibly clear visualisation 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 two independent control loops (optional). This control functionality utilises 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.
