DDC SPECIALTIES PSXX-AR - DCC Solid State Power Shield Auto Reverser / Circuit Breaker / Tortoise Scale = All

DCC Specialties PSXX-AR Power Shield Auto Reverser / Circuit Breaker

• Auto reverser

• Circuit breaker

• Automatically control reverse loop turnouts

• Accessroy decoder for turnout stall motors such as the Circuitron Tortoise

• Block detection

• Network Status Feedback

• Outputs for LED Indicators: Remote LEDs can be added to monitor the input/output power and the status.

• 4 Indicator LEDs on the board: Booster power (green), 2 x Block power (green), Block shorted (red)
  
  
  • LED output DCC power in from booster
  
  
  • LED output DCC power out to track/LED output turnout position/track phase
  
  
  • LED output short circuit
  
  
  • LED output block occupied
  
  
  

• Select Trip current values 1 – 10 in integer steps (1, 2, 3, …., 10) using CV 49

• Jumper Select Current limits of 1, 2, 3, or 4 amperes

• Power On/Off by DCC: Turn on/off output track power with your DCC Throttle!

• Manual or Automatic Reset: Automatic reset: Breaker tries to reset every 2 seconds. Manual reset: Once the breaker trips, it remains off, ensuring complete isolation of the faulty block. The breaker is reset either by a switch or by a DCC command.

• All Solid State Operation: Fast, solid state design with reliable quiet action.

• Adaptive Load Reset: Electronically determines if the overload is a real short or due to excess capacitance in sound decoders or lighted passenger cars.

• Auto Stop with DCC Reset: A photocell can be connected to a PSXX input. Normally, covering the photocell will not cause any action. If the photocell is armed with a DCC command, the PSXX will turn off the next time the photocell is covered. A DCC command can restore the track power when desired.

• Photo Cell Controlled Block Power Off: Stop position control and occupancy detection for hidden tracks.

• Block Detection: Either a photo cell or block current draw can be used to detect a train in a block and to trigger a Block Occupied output. The current trigger level is programmable.

• Block Occupied Trip point can be automatically set to compensate for current flow in unoccupied block

• Very Low Voltage Drop: Total breaker on resistance is less than 0.060 ohms, so the PSXX has a very low voltage drop even at high currents. Better than detectors that use a diode voltage drop.

• Programmable Power Up Status: When power is applied to the layout, the PSXX can be set to always turn on, always remain off [power on as needed by DCC command], or to use the power status present when the layout was last shut down.

• Network Feedback: Isolated outputs designed to provide Block Occupied, Block Shorted, and Power Status to a discrete interface for remote display or computer control.
  
  
  • Will work with Digitrax LocoNet, NCE Cab Bus, ESU ECoS, and Lenz XpressNet interfaces.
  
  
  

• System Reset: CV63=42 sets all CVs and addresses to original factory values.

• Output for Audio Alert: An audible sounder can be added to the PSXX to provide an audible alert if there is a short.

• No Power Supply Needed: The PSXX uses the track DCC power to supply its operating power. Each PSXX draws less than 0.04 amperes.

• Easy to Install: With 4 mounting holes sized for a #6 screw.

• Flash Programmable: The PSXX firmware can be updated by Tony’s Train Exchange as new features become available or if older units need to be matched to a recent purchase.

• Discrete Input allows on/off control of track voltage for yard or other track section isolation. Compatible with any system that has a relay or isolated transistor control output including LCC, WiFi, etc. or can be used with manual toggle switch.

• +5V and Ground Outputs for powering LEDs, no resistors needed
  

• Power On Status can be on, off (yard or staging sections), or status at power down.
