Rail signal device

EABS

Electronic Automatic Block System

The Electronic Automatic Block System is a device that transmits train operation information within the block section through optical communication between block devices and controls the block signal during train operation based on train tracking logic and the Fail-Safe principle.

Feature

  • Type Approved EABS
  • Station Equipment(sil4 certification)
  • Real-time Comparison of Dual Relay Systems
  • Dual optical network
  • CBI and interface can be implemented via relay I/O, identical to the existing equipment.
  • Safety system implemented with dual relays in two-position system
  • Implementation of fail-safe output operation using a system safety relay
  • Dual redundant rectifiers with load-sharing functionality
  • Safety functions equivalent to CBI
