Non-volatile elements

Description
Non-volatile elements behave like signal conditioners.
The output signals remain after failure of the supply voltage.
If an input signal is pending, the signal conditioner can issue an output
signal according to the chosen signal conditioner type:
• Non-inverting
• Inverting
• Edge rising with memory
• Edge falling with memory.
You can set the output response.
The non-volatile element consists of:
• Two plugs (input and reset)
• One logic component
• One socket.
Overall, the following are available:
– Two non-volatile element s 1 to 2 for BU1
– Four non-volatile element s 1 to 4 for BU2.
