AutoSignal - Colour light signal controller
Introduction
This AutoSignal can control any combination of 2, 3 or 4 aspect
colour light signals with the following features:
User selectable 2, 3 or 4 aspects.
Switchable feather with divergent route display.
Relay driver (
can operate ABC braking or track section power
on danger signal
).
Configurable flashing with 3 aspect signal (
four aspects with
three lamps
).
Automatic detection of a diverging route with 4 or 3 aspect
(
flashing, double flashing)
when feather set.
Automatic occupancy sensing using either infra-red
(analogue) or current sense (
DCC
) detectors.
Adjustable timers to simulate successive blocks at end of
scenic sections.
Automatic communication between upstream and
downstream signals and divergent path.
Uses jumpers to set personality.
Built in power distribution for upstream and downstream
signals.
Designed for 12 Volt LEDs.
Available in common cathode (
common negative
) and
common anode (
common positive
) versions.
On board test lamps for easy setup and testing.
Built in power supply for infra-red sensors.
Powered from 12 V regulated power source.
Personality is set per AutoSignal, you can mix two, three and four aspect signals as
necessary.
MegaPoints Controllers use
static sensitive components
that must be handled with
care.
Avoid
touching
any
components or the circuit
printed on the bottom of
the board.
Avoid placing the board on
any
metallic
surfaces
including track.
DO NOT connect any part
of the AutoSignal directly to
track.
You
must
use
appropriate
sensors
or
switches
to
provide
electrical isolation.
