PCD2 Series controllers

PCD2 programmable controller

Although now obsolete 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.

The PCD2 series has some crossover with the later PCD3 series and is able to use some PCD3 input / output components.

PCD2.M110/M120/M150

Maximum of eight input/output modules (or sixteen with an additional expansion housing) providing 128 digital I/O (255 with expansion modules). Both PCD2 and PCD3 modules may be used in an expansion housing of the appropriate type.

PCD2.M170

Eight standard input/output modules can be expanded with up to an additional eight PCD2 modules or twenty four PCD3 modules providing 128 digital I/O and up to 510 digital I/O with PCD3 expansion housing.

PCD2.M480

Eight standard input/output modules can be expanded with up to an additional eight PCD2 modules or fifty six PCD3 modules providing 128 digital I/O and up to 1023 digital I/O with PCD3 expansion housing.

The PCD2 can be snapped onto two 35 mm top-hat rails according to DIN EN60715TH35 (formerly DIN EN50022). The PCD2 can also be screwed to any other flat surface with 4 M4 screws; the grooves provided for this purpose can be accessed by lifting off the snap-on cover.
