ECIO PLC

Cheap, DIY and with CAN!

Published in issue 375, March 2008

ECIO PLC
Here’s the first real-life application of ECIO modules introduced in the October 2007 issue of Elektor. An ECIO acts as the brains of a PLC board that has relays, opto-isolators, CAN (!) connectivity and an LCD. All this I/O capacity together with Flowcode allows the board to act as a versatile, powerful PLC for quite complex control and automation projects. The LCD module is used to display ASCII characters to the user as a means of troubleshooting during the software development stage or for monitoring the system.

The copper track layout of PCB # 070786-I has been modified in the relay area to ensure electrically safe copper track/component wire distances when 230 VAC loads are used on the relay contacts.

The PCB modifications do not affect the circuit operation or functionality as described in the article.

PCBs sold separately as well as contained in the kit supplied for this project, are suitable for use with 230 V loads within the constraints mentioned in the article. Updated PCB artwork files are available under "Downloads".
