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.
Quad-Pic Servo DCC Accesory Decoder
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.
Fascia Controller for use with Quad/Octopus II 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.

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 use with Quad/Octopus II 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.
FCB012 $3.25 USD
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.

4 Relay Daughter Board Add this board to the Quad-Pic by plugging it into the expansion port and you have 4 relays for switching power (1 Amp per relay) to the turnout frogs. Or use it as a general purpose relay to switch power to another accessory using DCC or the manual controllers. Comes with 4 connectors with a 3-wire cable for connecting up to the frog and track.
QDB001 $12.00 USD
New - Remote Relay Daughter Boards
Put your relay closer to the turnout.
DPDT - add both a signal and a frog.
Remote DPDT Relay Board This remote relay plugs in to the breakout daughter board (below) and gives you two circuits for powering frogs, signals and so forth. Board has a 12V, 1A hi-sensitivity relay that draws just 13 mA, relay drive circuitry, and a terminal block for easy wiring. Can also be used without the Quad - red wire, 12V, black wire, ground, white wire, signal (0V = OFF, greater than 1.4V is ON). Comes with a 12" extension cord - extra length can be added with servo extensions.
RDR001 $7.00 USD Qty 8+ $6.00 USD
Remote Relay Daughter Board Add this board to the Quad-Pic by plugging it into the expansion port and you have 4 ports for plugging in the remote relay board above.
RDB001 $2.00 USD
4 Stall Motor Driver Daughter Board Add this board to the Quad-Pic by plugging it into the expansion port and you have can drive 4 stall motors (i.e. TortoiseTM). There is a small pot that is used to change the drive voltage (~4.5V to 10V) in order to change the speed for the motors. The servo ports are not affected by this add-on and can be used at the same time.
