Block Watcher |
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.
