Does anyone know the atlas #6924 non-derail circuit board power schematics?
Replies sorted oldest to newest
You can see the various schematics here, just scroll down to the 6924 section.
Here is a link to the Atlas website, 6924 relay board, non-derail/power routing wiring diagram.
Also a very good thread when the #57 Push button switches were first available. There are three pages of information via this thread. Click to link.
Thanks Mike
This helped, but I am still trying to understand how the board actually works
Here is a post from early this year indicating what each wire and terminal are used for.
6924 relay boards installed. Here is a link to a very good thread we did August 2011 on the 6924 relay boards. And the #57 controller. Three pages of detail. Click on the underlined phrase to link. You need to change the tread title to include Atlas 6924 boards. Best wishes with your project, Mike.
Relay #18 Combination cross over set. (There are two Atlas O54 switches controlled simultaneously from this relay). Note that JP jumper must be removed for this multiple relay power routing application.
Left side wiring.
Green (In A) Through Input, note the small grey twist connector, combining an isolated track input, and an IC controls ASC 3000 switch controller input.
Red (In B) Out Input, note the small grey twist connector, combining an isolated track input and an IC controls ASC 3000 switch controller input.
Black. (SW PWR In) Switch motor power from fuse blocks pictured to the left. (3 amp maximum) (Second picture).
White (not shown) (Switch motor common) not wired through the 6924 relay board.
These wires are connected to a common buss bar pictures above the grey wire tray. (Top Third picture).
White (COM 1) (fused 3 amps) Track power center rail from the Atlas switch location back to the relay board. Note white wire fuse block right marked #18
Red (C1(1)) Power routing, Through throw. Connected to the curved short dead rail, center of the switch.
Green (C2(1)) Power routing, Out throw. Connected to the straight short dead rail, center of the switch.
Right side wiring.
Green (OUT A) Switch motor through, intermittent, (timed out) power.
Red (OUT B) Switch motor out, intermittent, (timed out) power.
Yellow (COM 2) (fused 3 amps) Track power from the switch location. Horizontal fuse block above the relay board.
Brown (C1 (2)) Power routing Through. Connected to the curved short dead rail, center of the switch.
Blue (C2 (2)) Power routing Out. Connected to the straight short dead rail, center of the switch.
White/Red Brown thermostat cable is relay board power daisy chain to all 21 relay board. Red is Aux power and White is Aux common.
thank you mike
i am very new to this and i am trying to connect cobalt turnout motors to the non derail board. your help will get me in right direction, will post when (if) i am successful.
Thanks
