Melsec Q55B extension base
Use extension base units (also known as extension racks) in systems that require more modules than can be accommodated on the base unit. Extension base units are available with a slot for an additional power supply (Q6xB) or without (Q5xB). Use Q6xB extension bases in systems where the current supplied by the base unit power supply is insufficient for the whole system. Up to 7 extension base units may be connected to the base unit, allowing a total of 8 bases. The 8 base units may be extended over a distance of up to 13.2 m (43.28 ft). The maximum number of installed modules is 64. If your system requires more modules or greater distances, consider using a network to link the system together.
