PCA-80:
Lighting controller board. PCA stands for Power supply, Clock signal
generation and Address line control to it's self and any PBZ-08 expansion boards
connected to make a desired system.
For an eight channel system, the PCA-80 logic controller contains the first eight outputs.

|

|
PBZ-08 - the 8channel expansion board plugs into a PCA-80 or
another PBZ-08. Each addition of a PBZ-08 adds eight more parallel channels to the
controllers configuration.
|
Assembled logic system:
Add up all the parallel channels needed and snap them together - shown is a 24 channel
controller. |

Easy
mounting:
Circuit board dimensions designed for easy mounting using Augat's Snap Track board
mounting products. Snap Track mounts like din rail. |
Heat sink:
Gold iridite aluminum heat sink - usually 8-1/4" wide - and for the length - (the
number of channels used / 4) * 1.8") + another 5/8" so relays aren't so
close to the edge. A 32 channel system would be 15 inches long. Once the
heat sink is cut, an aluminum flange is attached. |

Assembled lighting controller:
This system shown here uses one PCA-80 board to drive 24 solid state relays. Each of
the PCA-80's outputs are connected to 3 solid state relays. Notice that dual SSR's
are used saving space. The relays and the logic board are mounted to a large heat sink
with a flange mounted around the outside. This design is intended to be easily
installed in an existing or new electrical enclosure back, side or door. - keeping the
enclosure sealed. |
Cooling:
The view from the other side shows the mounting flange, heat sink and fan that are exposed
outside of an enclosure. This compact unit can be mounted in the back, side or door of an
electrical enclosure.
Other configurations are also easily integrated into custom applications - since this is
designed to be a highly customizable product. |
