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.
 
Provides a simple way to travel through reverse loops in digital operation. Automatic changing of polarity when passing the isolation gaps of the loop, travel through loop without stopping or changing direction, regardless of the direction the loop is traversed, adjustable sensitivity depending on current needs of the layout, maximum current load 3.5 amp.
