Interlock mode in a relay system refers to a safety mechanism that prevents multiple relays from being activated at the same time, typically to avoid conflicting operations. This mode ensures that if one relay is activated, all others are automatically deactivated, enforcing a mutual exclusion among relays.

For example, in a setup controlling multiple devices (like motors or lights), interlock mode would ensure that only one device is powered on at a time. This is especially useful in cases where activating more than one relay simultaneously could cause damage or unsafe conditions, such as in motor control where activating both forward and reverse directions at once could cause a short circuit or mechanical damage.

Cover/roller mode refers to controlling devices like blinds, shades, or shutters. It is commonly used in home automation systems for managing motorized window coverings.
