Accessory decoder for connecting four turnouts or signals with twin coil relays, Power supply may be either from a separate transformer or from the track power, Maximum current load of a single output is 0.75 amp continuous, peak 3 amp for maximum 1 second. Maximum total current load (as the sum of all outputs in use) 3.0 amp continuous.
 
Serves to safely divide a digitally operated layout area from a conventional DC operated area. Momentarily breaks the power supply to the conventional side of the layout when the isolation gap between the DC and DCC areas are crossed.
