Expandable Sequential Controller Unit

This expandable unit allows for sequential control of 8 relays, expandable up to 256. Relays will turn on for a user selectable time, (all relays share a time) and cycle to the next relay after a user-defined pause. The unit can also be set for manual control where two contacts will allow you to cycle “Forward” or “Backward” through the relays.
