Security assembly particularly for electrosensitive protection equipment

A security assembly notably for electrosensitive protection equipment, comprising

• two micro-controllers (MC1, MC2) separately receiving specific and synchronous information (input states) for processing said synchronous information and supplying respective outputs (S1, S2),
• the two micro-controllers (MC1 MC2) being connected through links (C1, C2) to make the running of the programs consistent, processing the two input states in the micro-controllers (MC1, MC2), and
• a comparator (K) receiving the outputs (S1, S2) from the micro-controllers (MC1, MC2) for transmitting a signal in the event of nonconformity between the two outputs (S1, S2), and
• wherein said security assembly comprises
• a re-writable memory respectively associated with each micro-controller (MC1 MC2), and
• an interface (M) common to the two micro-controllers (MC1, MC2) and connected to the two micro-controllers through a common micro-controller MC3 , for entering parameterization data for the functions of the two micro-controllers (MC1, MC2) performed by means of the common micro-controller (MC3).
