Switched Terminals
The YardMaster contains a latching DPDT relay which can switch
up tp 6 AMPS of track power.
When the “Switch A” sensor is tripped, the two Switch Common terminals will
connect to the “Switch A terminals”. Conversely when the “Switch B” sensor is
tripped the Switch Common terminals will connect to the “Switch B terminals”.
Since this is a simple relay there are no polarity or voltage restrictions.
(AC, DC or DCC can be switched).
Terminal #1 connects to either #18 or #20
Terminal #2 connects to either #17 or #19.
