QuadLN_S Relay Board

QuadLN_S Relay Board


The QuadLN_S Relay Board contains a 5 Volt Relay with DPDT contacts along with drive electronics. The board uses a high sensitivity relay to minimize 5 Volt supply loading and permit many relays boards to be used with a single QuadLN_S. Includes a 12″ cable.


  • Plugs into any QuadLN_S I/O Port or any Signal Board output
  • Provides DPDT contacts rated for 2 Amps @ 24 Volts DC or 1 Amp @ 120 Volts AC.
  • Relay current is just 30mA when activated and this allows multiple Relay Boards to be used with a single QuadLN_S or Signal Board
  • Contacts can easily be wired in parallel with jumpers
  • “Rising cage clamp” screw terminals for reliable connection
  • Includes 12″ cable to connect to I/O Port then add standard servo extension cables as needed
