Protections All the inputs and outputs are protected against spurious undervoltages by clipper circuits. A 75 ohms resistor ensures the protection against the spurious application of 28VDC or 115VAC. This resistor acts as a fuse at each input and output, except on relay contacts. All the analog and discrete inputs are filtered.

Power supply of position transducers. Each COM and MON unit supplies the position transducers that it uses: - +10VDC power for side stick transducers (ANI 1)
-7VAC 1953 Hz power for inductive transducers (ANI 2, ANI 3, ANI 7).

Computer architecture
(Ref. Fig. 005)
Each unit (COM or MON) has the functions below:
-acquisition of digital inputs
-generation of digital outputs
-main processor
-
acquisition of discrete inputs
-
acquisition of analog inputs
-
generation of analog outputs (COM only)
-
generation of discrete outputs
-control of switching relays.
The acquisition of digital inputs and the generation of digital
outputs are performed by specific interfaces and by a specialized
processor located on the CDG and MDG boards.
The main processor (CPU and MPU boards) executes the servoloop
functions and calculates the laws.
It supplies the data required for the calculation of the laws and of
the logic to the slave processor (slave processing board, CSP and MSP
boards).
It communicates with the specialized processor of the digital input/
ouptut boards via a buffer memory.
The main processor directly manages the acquisition of the discrete
inputs.
