"safety valve" control cuts down the gas supply in case of a mis-communication or error.
I Think some EN298 certification...I am not very sure abt whether this is the regulation or not.The above mentioned "I believe" also applicable for this.
The intrinsic safety issues are already taken into account I believe.
But I will narrow down the ploblem..
Suppose a microcontroller is used to drive a safety valve may be through some optocoupler logic. This controller is powered through a 7805.
Can I use the same 7805 to power another...
Dear all,
Is it possible to supply 5V from a single 7805, to multiple number of ICs, some of which are safety critical?
I have one PCB having ICs meant for the safety critical applications.
And also have another PCB for the Human interface.
Can I directly get the 5V from the first PCB...
