PCD1 Series controllers

PCD1 programmable controller

PCD1.Mxx5 ranges are supported by SAIA as a repair service until 2018 and they will also provide support on the complete range but no sales of these PLC's. Some spares and replacement processors are still available either directly from MACOL or from another source that we may be able to help you locate.

For customers wishing to update to a modern controller we are able to reverse engineer undocumented software and re-write it for the replacement system. This is often the most cost-effective solution offering like-for-like functionality with minimum downtime.

The manual for the PCD1 and PCD2 series is available for download as a ZIP file here.
