Total Counter/Time Counter (DIN 72 x 36) H7HP 9
Specifications
■ 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.
