Ratings
Note: 1.
Contains 20% ripple (p-p) max.
2.
Only a non-voltage input (NPN transistor) is possible for the key protection input. The key protection input will be a non-voltage input even
if the NPN/PNP input mode is set to PNP. Key protection is used to prohibit operating the Reset Key. The reset input terminals will still be
functional.
