Universal Signal Controller
Penta’s SignalLink™ is the single solution to
efficient and economical direct replacement of relay units. The
SignalLink™’s compact design and low cost make it a valuable member of a
Signalman’s toolbox. That means fast, on-site repair of signal systems and
replacement of unreliable relay field units. A variety of codes are
available including 504, 506 and 514. Also SCS128 and
GENISYS serial data formats..
- Single Board Design with Quick On/Off Connectors – Compact
design makes the SignalLink™ easy to transport and install. Terminal
strips permit efficient maintenance and replacement of relay based code
- Code Translator & Serial Port – Code format can be
encoded/decoded via data modem for transmission other than DC current
facilities, e.g. microwave, fiber optics or audio lines.
- PROM-based Attributes – SignalLink™ units can be converted
between various code formats by just changing a PROM
- LCS and PUP Circuitry on Single Board – Both Line Code
Storage (LCS) and additional storage (PUP) circuitry are on the single
board for convenient and universal application.
- Live Disconnect – In the event the SignalLink™ detects a code
line failure, the Tx is disconnected for a predetermined period of time
with automatic retry.
- Microprocessor-Based Software – No calibration/adjustment of
the timing format is required upon installation.
- Field Proven - In service for over 20 years.
Relay Unit Repair: The SignalLink™ is a direct
replacement for most relay based field units, which can mean both short
and long-term maintenance savings. SignalLink™ provides an economical
alternative considering the labor and material cost of repairing
outdated relay units (not even accounting for the loss in signal system
downtime). The SignalLink™ can easily be carried by the signal
maintainer and quickly installed without recalibration of message
timing. Additionally, each individual code’s attributes are located in
an easily- replaceable PROM on the SignalLink™’s single board.
Therefore, the SignalLink™ can be universally applied to a railroad’s
multiple code line systems.
New Installations and Office Units: SignalLink™
is the ideal, least-cost approach to installing new code line systems.
The unit arrives pre-programmed with the required code and its compact
design requires less space than the interface boxes of most relay
units. With the provided serial interface, a CRT Office Unit can be
configured to provide an efficient presentation of code line information
|Penta’s SignalLink™ is a member of the
Penta family of communication and control products. In addition to the
controller, Penta offers a Code Line Test Set for line or field unit testing
and calibration. The test set consists of a PC with Code Line Adapter and
provides on-site testing of field units, convenient testing of code lines
and performs excellently when used as a calibration instrument for repair
