AD-8fx will tolerate a very wide track bus voltage range and offer exceptionally low current draw while static (effectively zero). AD-8fx is designed to connect straight to track power or your accessory power bus.

Because it only permits drive power for the few seconds needed to reliably change a Cobalt Classic or Cobalt iP Analog point motor or other device it is controlling, so it will never take important power away from other operations.

Addressing is so easy that we call it learning rather than programming – there are no CVs to set for addressing – All it needs is the changing of a simple switch to make it ready to teach – once that is done all you need do it act as if you are already changing it at the address you want it to be, return the switch to the run position and its done.


  • Screw connectors means no need to solder.
  • One power input point for all outputs
  • Simple 2-wire output to the device being controlled
  • 3 low power terminals for direct connection of panel LEDs or signal.
  • 3 switch terminals with the option of one or two push-button switches
  • 1 terminal which swings to (+) or (0) voltage for direct connection of position feedback to systems that require it – or any computer IO interface at all.
  • Simple “Learn” / “Operate” 2-position switch for easy addressing.
  • Special “Self centering’ commands to work with Cobalt iP Analog (Using accessory addresses, Command 199 and 198 introduce or cancel self centering).
  • Command 197 (Using an accessory command) will electronically “swap” the change direction of AD-8fx
  • Flat back for easy layout mounting
