Uhlenbrock 67810 Servo-decoder with switching output 67810 Fiche De Données

For the “track”, “Trafo” and the relay contacts, 16 small 
push-on covers are included in the contents. The wires are 
stripped approx. 5mm, held into the slot from the underside 
and fixed with a push-on cover. The slot in the push-on 
cover points toward the wire‘s isolation. 

The “track” connections are connected with the track 
connector of a DCC or Motorola digital center. In this 
instance the decoder is powered via the track. 

Note: Since most Servos move uncontrolled when supply 
voltage is switched on (this is a servo characteristic and is 
not produced by the servo decoder), we recommend, to 
connect the “Trafo” terminals to a 16V model railway 
transformer. This will ensure that the uncontrolled 
movements of the Servos will only occur when the entire 
layout is switched on. 

Each servo decoder has four 3-pin headers for connecting a maximum of four 
Servos. The Servo’s plugs are plugged onto the appropriate header so the earth 
wire (usually black or brown) is at the front edge of the circuit board.
