Modular automation device

Automation device comprising a modular assembly to be used with a hardware element and including a primary group (10A) of modules located on a common frame associated with a primary zone of the hardware element. The primary group includes a control unit (20) capable of carrying the command-control signals, a feeder unit (21) capable of distributing feeder power (Uin, Uout) for the automated units at a minimum, a number of functional modules (22), with, between the modules, a first link (SB) to carry control signals and, at a minimum, feeder power for the modules, and a second link (PB) to carry the feeder power for the automated units, and a terminating module (30),

• characterized by the fact that:
• the device includes at least one secondary group of modules (10B) in the hardware element's secondary zone with both a lead module (24), and first and second links (SB, PB) extending those of the primary group (10A),
• a linking cable (C) associated with the first connection (SB) and constructed to carry shielded control-command signals and power at a feeder voltage (V1) for the modules. The cable is connected to the terminating module (30) of the primary group and the lead module (24) of the secondary group (10b).
