51809 SwitchPilot Adaptor for signals with common cathode, Set of 2 for 8 OutputsOur SwitchPilot decoders cannot only control point mechanisms but also daylight signals. Most modern signals are equipped with LEDs. Usually the anode connections of multi aspect signals are combined in order to reduce the number of wires. Some manufacturers (e. g.: Viessmann) combine the cathodes and for that reason these signals could not be controlled with the SwitchPilot in the past. Our new adapter provides the solution. Simply plug the adapter
