DCC Specialties Block Watcher

$27.95

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

This detector puts the power of a microprocessor to work analyzing the current feed to the rails. This detector has been designed to eliminate many of the installation problems associated with the installation of signal 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 signaling 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 signaling 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 signaling system using less than 30 Volts and will switch up to 1 A of current.

MSRP is $31.95.
