Multiple mods on Power armor?

I noticed some power armor mod cards look different than others, such as the Sensor Array which looks like a power armor card. It gives +1 PER and quick action shots dont suffer a -2 penalty. Other power armor mods such as Boosted Servos look like all other armor mods and adds +1 STR. Are these considered “different” mods and can be used on one set of power armor? Or can power armor only have one mod?

Only one mod. Table on page 57

Mods are modifications to Weapons, Armor
and Power Armor which improve their
capabilities. Up to one Mod card can be
attached to an item which is of the same type,
i.e. Rifles can only be fitted with Mods showing
the Rifle weapon type icon.Mods cannot be
fitted or changed during a battle.
