Micro Singlet Servo DCC Accessory Decoder

Back in stock - we scored the parts!



Control a turnout using the Micro Singlet, a servo controller with built-in DCC accesory decoder for controlling a single servo.
Skill level: Simple - similar to installing a stall motor switch machine.  For DCC you should understand how to operate accessories with your DCC system.


Singlet Micro DCC Accessory Decoder

Designed exclusively for switching turnouts with a servo
No buzzing! - servo turns off at end of throw
Simpler setup - center the servo and mount - no alignment needed
Switch with DCC or the included fascia controller or both
Teach the DCC address with a the programming jumper on - no CVs to program

The singlet Micro Singlet is a simple servo decoder designed to drive turnouts and only turnouts.  It solves the problem of servo buzzing by turning the servo off at the end of the throw.  Special circuitry and programming has been built in to accomplish this without a large jerk at restart.
  The Micro Singlet works uses a pushbutton for controlling the turnout manually for local control.  The same fascia controller used by my other servo boards can be used.  It will not work with a toggle switch.
  Installation is simple.  It is designed to work with a servo under the table using the geometry of the SwitchWright bracket.  This mounting method provides an over the center spring action that keeps the points in place after the servo turns off.   After years of trying various methods, this method really works the best and avoids the servo buzzing that happens when they are fighting to keep the points in place.  Centering for mounting the servo is done by holding down the fascia controller button until the servo drives to the center.  A tap on the button releases it from centering mode.

Micro Singlet Servo Decoder Board Only
Just the Micro Singlet board.  Requires a servo.  For manual operation a pushbutton or a fascia controller is needed.  If you plan to use DCC you can use a single fascia contoller to initially set up the servo centering while mounting and then remove it. Power is provided from the DCC bus or from 8-24V DC if you just want to use the fascia controller. 
Each unit requires about 0.15 A when moving points and about .025 A when resting.
This is a DCC accessory decoder and uses the switch/accessory keys on your DCC controller.

Micro Singlet Servo Decoder with Fascia Controller

Includes the micro singlet, with a Red/Green Bi-color Fascia Controller.  Power is provided from the DCC bus or from 8-24V DC if you just want to use the fascia controller.
Each unit requires about 0.15 A when moving points and about .025 A when resting.
This is a DCC accessory decoder and uses the switch/accessory keys on your DCC controller.

Miniature Servo (SG90)
Subminiature 9g servo.  These have plenty of power for hinged point turnouts and solid rail point turnouts. If the point rails are hinged then the rail size is not an issue - it has been used up to G scale, otherwise code 100 is max for non-hinged points . Size 1.25" wide (including mounting tabs) x 0.5" deep x 1.125" tall.  Servo lead about 7".  The label on the servo and the lead colors may vary between batches.  Works with all of our boards. Every servo is tested before shipping.

Y extension
The Y extension can be used with the fascia controllers to provide two control points for one switch.  

Y cables can be used to connect more than one fascia controller to a single input.
12" Y-cord
The Y can can also be used with the fascia controllers to provide two control points for one switch (For Octo III the Mntry jumper must be on).  
Y cables can also be used to attach two servos to one output.  Both servos will move in the same manner at the same time.  (Note: some users have had trouble getting this to work with some servo types).  
A third use is to connect a DPDT relay and a fascia controller to the same control input (NOT a servo output) so that a relay and a fascia controller can be used at the same time.

The video (left) shows the Micro Singlet and a servo mounted on a SwitchWright bracket. It also works very nicely with the Micro Switch machine as pictured above.
