The unit has 2 relays and a semi-circular set of 10 contacts with an arm that connects to an incrementing set of contacts with each dc pulse given to the relay. There is another relay for resetting the arm back to "home".  Has 3 wires, one is common, one steps the relay and the third resets back to home.
