Features
- Control two servos independently with 3 positions each
- Speed Controllable from very slow to very fast
- Drive circuitry for external LED indicators - common anode OR common cathode
- Inputs for momentary pushbuttons
- Bounce Simulation - blades bounce at end of throw
- Variable Bounce Amplitude
- DCC accessory decoder built in (can be used with JMRI PanelPro)
- Anti-backlash for stub switch center position ensures accurate positioning each time
- Time-delay option - simulates a signal system by turning from red to yellow to green with a time delay.
- Can be used with most signaling systems such as CMRI or Logicrailtech
This is the Mark III version updated in April 2015. It has a more powerful switching voltage regulator and larger easier to wire terminal blocks on the I/Os. The firmware is identical to Mark II.
(Note: not for 3-way turnouts, more properly known as lap turnouts, which are actually two overlapping but independent turnouts. For those use two servos driven by singlets or half of a quad.)
