Note the following.
(1.) The 6924 relay boards in addition to inhibiting burn-out also provides the ability for logical power routing through dead spots in switch track circuits. You would have to add the DZ 1008 relays to DZ 1000's for this function.
(2.) 6924 board installation requires installation of automatic non-derail wiring, which IMO, is much better than the spring-loaded non derail provided by Atlas.
(3.) Atlas 6931 dwarf signals, or other signals, can be added from the relay board. There are (2) sets of NC/C/NO contacts on the board.
