Disclaimer: This posting is a work in progress. I’ve mode this some years ago and was asked to provide some documentation:
I have parts of a SAIA PCDII that I wanted to make use out of. The ourput boards have 6 relais each and 8 of them are connected to a backplane connector. This makes 48 mains voltage (low current) switchable channels.
Confusing what I mean? Have a look at this video
I’ve found some of the pictures I took while working on this and just a few days ago I found the box with the hardware itself.
For now the old pictures.
Unfortunately I just this one picture of the pin out.
- redraw schematic
- Figure out connector type
- sketch pinout of PCD2.A220 board
- sketch pinout backplane
- comment ino file
