Ansaldo STS N4519107001 Printed Circuit Board

Ansaldo STS N4519107001 Printed Circuit Board is a cab signal generation module PCB used as a coder output auxiliary within Ansaldo STS signaling systems. Also listed as N4518107001 in some catalogs, this board belongs to the family of plug-in PCBs designed to support coder outputs for track-circuit signaling. The N4519107001 designation identifies a "Coder Output Aux" function, providing dedicated outputs for the cab-signal coder subsystem that drives track-circuit encoders. In legacy signaling deployments, boards from this N-series lineage were used as modular components in signaling cabinets to support coded track circuits and cab-signal signaling, aligning with architectures that rely on coder-generated outputs. This description reflects the part's intended role based on historical Ansaldo STS documentation for the N4519107001/N4518107001 family; for exact pinout, electrical characteristics, and connector standards, refer to the original equipment manufacturer documentation and the system wiring diagram to ensure proper substitution in a legacy installation.
