SNAP PAC Racks
Description
module security, SNAP PAC racks have provisions for two 4-40
by ½-inch standard machine screws to hold each module in
position.
SNAP PAC I/O mounting racks are designed to hold an
intelligent SNAP I/O processor—a SNAP PAC EB-series or SB-
series brain or a SNAP PAC R-series on-the-rack controller—
and several I/O modules. Both standard wired controllers and
brains and Wired+Wireless models are mounted on these
racks.
All SNAP PAC racks offer panel mounting and the option of
DIN-rail mounting. DIN-rail adapter part numbers are shown in
the table below. For more information, see form 1772, the
SNAP TEX Mounting/Wiring Tools and Spare Parts Data Sheet.
Since SNAP analog, digital, and serial I/O modules all have the
same footprint, customers using SNAP PAC racks can mix all
these modules on the same I/O mounting rack. Field devices
are wired directly to the top-mounted connectors on the
modules plugged into each rack, or through breakout boards
when additional wiring space is required. (See form 1756, the
SNAP TEX Cables and Breakout Boards Data Sheet, for more
information.)
SNAP PAC racks require a 5 VDC power source. One power
supply can usually power the rack, the I/O processor
(controller or brain), and all modules on the rack. See form
1120, the SNAP Power Supplies Data Sheet, to choose a power
supply.
Part Numbers
SNAP PAC racks can accommodate up to 4, 8, 12, or 16 I/O
modules. Part numbers ending in -FM are Factory Mutual
approved.
