The Block Watcher™ is a new concept in block detection.

This detector puts the power of a microprocessor to work analysing the power feed to the rails. The detector has been designed to eliminate many of the installation problems associated with the installation of signalling systems.

The Block Watcher comes ready to install, all you have to do is to connect it between the DCC booster or circuit breaker and the rails. Then connect the detector output switch to your signal system.

The Block Watcher™ has many uses and applications.

It can not only be used as the basis of signalling systems, but can also be used to indicate occupied blocks or triggers for Stop-On-DCC decoders. The Block Watcher is powered from the DCC input power and eliminates the need for an added external power supply. The output is optically isolated so the signalling system can be separate from the DCC signal and thus minimize the interference with operation of the signal circuits. The detector will handle up to 20 Amps of DCC current. An automatic adjustment for leakage current up to 130 mA is provided. Detection output terminals are available for a switched output and remote LED block detect indication. The bi-polar output can be used with any signalling system using less than 30 Volts and will switch up to 1 A of current.

Here are the special features:

  • All Solid State Operation: Fast, all solid-state design with reliable quiet electronics.
  • No Power Supply Needed:  Develops power from the DCC input connections.
  • Very Low Voltage Drop: The resistance is less than 0.060 Ohms, very small voltage drop.
  • Adaptive Block Leakage Detection: Electronically determines the amount of leakage current in the block when power is turned on. The current can also be set with a CV value up to about 130 mA.
  • Stabilised Setting for Current Trip Level: This prevents the block detection from fluttering on and off when the current is near the trip level.
  • Block Detection Option: Block detection can be turned on with an Accessory Command for testing signals even with nothing in the block. This feature can also be used to turn the signals red to protect a crossing.
  • Block Detection Output Isolated from Track Power: The output switch is totally isolated from the track power. This eliminates many wiring problems when combining signal circuits and track power.
  • Outputs for LED Indicator: A single LED output can be used for a remote location.
