The relay8 card is a low cost solution
that allows DMX512 to drive up to eight contact closure
circuits. It is provided as an open PCB module to allow
for maximum flexibility in custom installations.
DMX512 Controlled Relay
Eight 500mA Pilot Relays
In use, the
red LED will be lit when power is supplied to the unit.
The green data LED will light if valid data is being
received, and will blink if the address switches are set
to zero, if the start code is not zero, or if the unit
is in 600 test mode. If data are lost, the green LED
will turn off after 1 second and the relay output will
be maintained, or the relays set to zero depending on
the setting of SW1.
data are provided by a single 8 pin .1" header. A mating
connector is the molex/HE14. The relay connections are
by way of two removable eight pin screw clamp style
headers. This allows installed cables to be wired and
tested in advance.
are controlled by a block of 8 addresses starting with
the address set on the address switch.

hundreds BCD switch set to six the unit will enter the
