The Quad can be used to control 4 turnouts using servos. It has a DCC decoder built in and 8 IO ports for switches to control the turnouts locally and for driving indicator LEDs. An expansion port can be used to add relays for powering frogs or other devices.
Use to control four turnouts using model R/C style servos. Servos are easily mounted under the turnout and provide a reliable and inexpensive method to switch points. the Quad is very versatile, you can move the points by DCC commands from your throttle, use buttons on the fascia, control from a signal system or any combination of the 4. LEDs can be hooked up to indicate the direction of throw.
DCC - The unit can be completely programmed from the buttons and LED indicators on the board or you can use programming on the main to set the CVs. The DCC address is easily programmed by setting a jumper and then issuing the desired accessory address from your throttle. This avoids the confusion of how DCC Accessory addresses are stored in the CVs.
Power - The board has a beefed-up and separate regulator circuit for the servos to eliminate power loss to the microprocessor. The best way to power the board for DCC is to use the specially designed DCC Accessory booster which can power up to 6 Quad-Pics. For DC use any power supply from 7.5-18V AC or DC can be used. It is also possible to supply 5V power directly to the servos. The servos are completely opto-isolated to prevent ground loops.
Expansion - The new design has provisions for adding daughter boards to expand the capabilities. One daughter card has relays for switching the frog power or controlling some other accessory. Another daughter board lets you add on stall-machines (such as the Tortoise™) - you can still use the servos at the same time.
Signals - Inputs for signal systems have been added. An expansion board that provides full opto-isolation of the signals is available soon. Download the Quad Servo Driver Manual
Quad-Pic Auto Programmable Servo Decoder
Quad servo driver and DCC decoder board. Updated version with a 2A switching power supply and auto-alignment of the servo positions.
Qty 3-9 $36.95 USD Qty 10+ $34.95 USD
Fascia Controller for SwitchWright/Quad/QuadLN/Octopus II/Octopus III/Micro Singlet This fully assembled and ready to use controller mounts on the fascia or control panel. Use for manual throwing of your switches and also provides feedback on servo position when used with DCC/signals. Has 2 yellow LEDs. Mounts using a #4 self-tapping screw (included). Comes with a 12" cord attached. 3-wire servo extensions can be used to extend the reach. By using a "Y" cable, two controllers can be added to one port to provide two control points for one turnout. Controller is 0.6 x 0.8 " in size.
FCB010 $2.50 USD
Single Color LED Fascia Controller Kit
Contains PC boards and parts needed to build 4 fascia controllers. The resistors are pre-mounted. An advantage of building from the kit is that you can substitute your own color LEDS (single color only - bicolors will not work in this version). Requires four 3-wire servo extension cords to hook up to the Quad/Octopus main board.
FCB011 $8.00 USD
Bicolor Fascia Controller for SwitchWright/Quad/QuadLN/Octopus II/Octopus III/Micro Singlet This controller is identical to the above controller except that it has two Red/Green Bicolor LEDs instead of the 2 yellow LEDs. Each LED alternates between red and green so both LEDs are lit whereas in the regular yellow LED controller one LED is on at a time. The LED colors in photo are a bit washed out due to the limits of photography. Other than the LEDS it is identical to the single-color Fascia Controller.
Qty 4-7 $4.00
Qty $8+ $3.50
Bi-Color LED Fascia Controller Kit
Contains PC boards and parts needed to build 4 fascia controllers with bi-color LEDs (3-lead type). The resistors and transistors are pre-mounted and the board tested. An advantage of building from the kit is that you can mount the components on a control panel anywhere you wish and then wire them back to the PC board. Requires four 3-wire servo extension cords to hook up to the Quad/Octopus main board.
Programming is done with these buttons and LEDs. All states are clearly indicated - no counting presses and getting confused.
Both servo and controller ports use standard 3-wire servo cables for simple hookup.
Neatly Place Your Fascia Controllers with Laser-Cut Recessed Mounts
Controller Drilling Guide
Recessed mount with a fascia controller in position ready for mounting on the layout.
View of the back showing the recess. Made from 1/8" laser-cut acrylic
Drill a 1/-3/8" hole in the fascia and attach with 4 screws in the corners.
Fascia Controller Mount
Made of precision 1/8" thick laser-cut acrylic, these mounts can be used to neatly mount your fascia controllers. Simply use a 1-3/8" hole saw to place on your fascia. The four included screws hold it securely in place and the recess keeps the button safely out of the way of bellies. The dark plastic makes the LEDs stand out. Comes as a kit that includes the 2 pieces and 4 screws. The pieces can be easily glued together with solvent designed for acrylic such as Weldon 3. (MEK and other styrene glues will NOT work). Just put the pieces together and flow a small amount of solvent on with a brush. Can be spray-painted a different color or used as is. Parts are laser cut by Monster Model Works.
Size 1.5" x 1.5" x 1/4" deep (without parts mounted).
