Technical Description
The PCI-32REL and PCI-32REL-B provide four parallel Reed Relay output
ports. The ports are organized as ports 1, 2, 3, and 4. The PCI-32REL comes
with a shielded dual breakout cable to two DB-37 male connectors that have
the same pinouts as the PCI-16REL, allowing the user to double the number
of relays while using only a single PCI slot. The PCI-32REL-B comes with a
different shielded dual breakout cable to two DB-37 female connectors that
have the same pinouts as the ISA 32REL-B. This option has all of the
A-side relays on one DB-37 connector and the B-side relays on the second
DB-37 connector, allowing users that only need the A-side of each relay the
option to buy only a single termination board, providing the B-side is not used
in the application. This also allows a smooth upgrade using the same cabling
for those changing from our ISA DIO32-B to the PCI bus.
Reed Relays
Reed relays provide very high quality, long life, low power, dry contact switch
closures. Reed relays are not suited for high current applications, and can be
destroyed by capacitive or inductive load switching. The relays are normally
open, and close when energized.
