GE Vital Logic Controller User Manual

GE

Transportation

Its track-proven technology and years of reliability have made
the GE Vital Logic Controller a rail industry leader in solid state
interlocking control in North America.

The multi-purpose VHLC provides control of power switch
machines and DC lighting of signal lamps. It offers a direct
interface to Electro Code track circuits and the DC track relays
for the plant tracks and provides internal code emulation of
most code system protocols.

The VHLC replaces most vital and non-vital relays at an
interlocking. Its software package, Logic Station (ACE), allows
signal design engineers to program vital signal logic for the
VHLC using relay logic diagrams.

The basic VHLC system consists of the chassis, power supply,
Vital Logic Processor, Auxiliary Communication Processor, and
Site Specific Module. Various configurations for different code
system emulations are available.

Specifications

The VHLC chassis has positions for up to
12 modules. Of these 12 slots, 9 can be
configured with various combinations of
input/output modules as required for a
specific application. Vital serial links allow
up to 3 separate VHLC chassis to be
connected together providing additional
expansion.

Accessories

Electro Code Track Interface

The Electro Code track interface
chassis receives, monitors, and
transmits track signals. It can hold
four Electro Code track interface
circuits. Each VHLC chassis can
interface with two of these chassis
providing eight Electro Code track
circuits.

The following circuit modules are
available:
Track Filter Module (9H)
Regulated Track
Converter Module (2R)
Track Receiver Module (7K)
Line Modules (2L, 7L, and 9L)
Filter Module (214)
Cab Signal Filter Module (CSF-XX-TC)
