Description

Description

Dummy PCB for Track Occupancy Detectors (GBM). Designed for use with real GBMs, this simple circuit board does nothing but adjust the rail voltage to that of real GBMs. The board cannot generate notifications. This version uses Schottky diodes, so the voltage drop is about 0.25 volts. This PCB is intended for SMD components, which when ordered are best assembled immediately by JLCPCB. There is also a similar PCB, but for Through Hole Technology (THT).

 

Dummy-Leiterplatte für Gleis Besetzt Melder (GBM). Diese einfache Platine ist für die Verwendung zusammen mit echten GBMs gedacht und dient lediglich dazu, die Schienenspannung an die von echten GBMs anzupassen. Die Platine kann selber keine Meldungen erzeugen. In dieser Version werden Schottky-Dioden verwendet, so dass der Spannungsabfall etwa 0,25 Volt beträgt. Diese Platine ist für SMD-Bauteile gedacht, die bei Bestellung am besten gleich von JLCPCB bestückt werden. Es gibt auch eine ähnliche Platine, aber für Through Hole Technology (THT).
