(see form 1756, the snap tex cables and breakout boards data sheet , for more information.) snap pac racks can accommodate up to 4, 8, 12, or 16 i/o modules. part numbers ending in -fm are factory mutual approved. the module and rack design allows modules to simply snap on the mounting rack. snap pac racks use a retention ra il locking system that holds modules securely to the rack. normally, a hold-down screw is not required. however, for applic ations that require additional module security, snap pac rack s have provisions for two 4-40 by ?-inch standard machine screws to hold each module in position. 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 . 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. snap-pac-rck8 (8-module position i/o mounting rack) shown with snap-pac-r1 controller and snap modules (all purchased separately) snap pac racks part numbers part description snap-pac-rck4 4-module snap pac rack snap-pac-rck4-fm 4-module snap pac rack, factory mutual approved snap-pac-rck8 8-module snap pac rack snap-pac-rck8-fm 8-module snap pac rack, factory mutual approved snap-pac-rck12 12-module snap pac rack snap-pac-rck12-fm 12-module snap pac rack, factory mutual approved snap-pac-rck16 16-module snap pac rack snap-pac-rck16-fm 16-module snap pac rack, factory mutual approved snap-fuse7.5ab 7.5-amp fuse, 25 pack snap-tex-drc10 snap rack din-rail adapter clip, 10- pack snap-tex-rec10w wide end cap for snap pac racks din-rail assemblies, 10-pack snap-tex-rec10n narrow end cap for snap pac racks din-rail assemblies, 10-pack
