Final answer:
A counter contact that will be closed (pass power) only in the counting condition would be identified as option D. OXO.
Step-by-step explanation:
A counter contact that will be closed (pass power) only in the counting condition would be identified as option D. OXO.
In electronics, a counter is a digital circuit used to count the occurrence of a specific event. The contact symbols O and X represent open and closed contacts, respectively. When the counter is in the counting condition (e.g., when counting a specific number of pulses), the contact will close and pass power, represented by OXO.
For example, if the counter is set to count up to 5 pulses, the contact will only close on the 5th pulse. Before and after the 5th pulse, the contact will be open (O). So, the correct identification for a counter contact that is closed only in the counting condition is option OXO.
