ETD1644 is an I/O expansion board with plug-in connection to Pixsys HMI, allowing acquisition and control of analogue/digital I/O on the HMI via RS485/Modbus RTU or high-speed bus CANopen. Device is included into Pixsys devices catalogue within development environment LogicLab for quick and straightforward integration into programs. 

I/O evailability includes 16 digital lines programmable as inputs and/or outputs, 4 universal analogue inputs and 4 analogue outputs mA/Volt.

It is also possible to acquire up to 4 encoders mono/bidirectional. 

User friendly, multimedia support and traceability

For the complete range of Pixsys products we provide technical support for installation, programming and operation via our online forum and via Skype.

Programming tutorial videos are available on our youtube channel.

As for the entire range of PIXSYS products, thanks to the QR code the traceability of the product is guaranteed for its entire life cycle; the information and documentation online can be also be accessed by reading the QR CODE that directs your mobile device to the product's technical specifications and verifies its warranty conditions.
