SNAP B-Series Racks Features Secure mounting for SNAP I/O modules plus a SNAP brain or on-the-rack SNAP controller Analog, digital, and serial modules on the same rack Panel or DIN-rail mounting Modules snap into place SNAP B-Series Racks NOTE: For racks to use with SNAP PAC controllers and brains, see Opto 22 form #1684, the SNAP PAC Racks Data Sheet. All SNAP racks offer panel mounting and the option of DIN-rail mounting. SNAP racks require a 5 VDC power source. NOTE: M-series racks (such as the SNAP-M64), used with SNAP Simple brains and SNAP-UP1-M64 controllers, have been replaced by SNAP PAC racks. See form #1684. SNAP-B4M, SNAP-B8M, SNAP-B12M, SNAP-B16M, and SNAP-D64RS racks are Factory Mutual approved. SNAP B-series mounting racks are designed to hold an intelligent SNAP I/O processor--either a SNAP brain or an onthe-rack controller--and several I/O modules. This rack family includes racks that are compatible with ARCNET and serial SNAP brains, including those using Modbus(R) and Profibus(R) protocols, and with some Ethernetbased SNAP Ultimate I/OTM on-the-rack controllers and SNAP Ethernet I/OTM brains. For specific processor compatibility, see "Specifications" on page 3. Since SNAP analog, digital, and serial I/O modules have the same footprint, customers using most SNAP B-series racks can mix modules on the same I/O mounting rack. However, module types, features, and positions on the rack vary depending on the capabilities of the brain or on-the-rack controller used. See the brain or controller data sheet for details. Field devices are wired directly to the top-mounted removable connectors on the modules plugged into each rack. SNAP Bseries racks can accommodate up to 4, 8, 12, or 16 modules. The module and rack design allows modules to simply "snap" on and off the mounting rack.

MC racks use a fixed terminal strip, while MC-P racks use removable connectors for easy maintenance (see enlarged view on the following page). Part Form 0784-140228 SNAP racks use a retention rail locking system that holds modules securely to the rack. Normally, a hold-down screw is not required. However, for applications that require additional module security, SNAP racks have provisions for two 4-40 by 1/2-inch standard machine screws to hold each module in position.

Most Ethernet-based I/O processors handle all these types of modules; other processors do not. See the processor's data sheet for details. 2 Power requirements shown are for a rack, a processor, and a full load of 2-channel analog modules (for the SNAP-D64RS, a full load of 4-channel digital modules). Power requirements for other SNAP modules are higher. See module data sheets. 3 "I/O Processor" means a SNAP brain or on-the-rack controller. 4 Four-channel SNAP digital modules can be used in positions 0-7 only. 5 Manufacturer's part number (not available through Opto 22).

SNAP B-Series Racks Mounting NOTE: If you are not using hold-down screws, the SNAP rack assembly should be mounted horizontally. Use the following steps to mount racks as shown in the diagrams on the next two pages. Preferred Method: Template (No product on site) Mounting holes are in sets of two, located on lower left and upper right with respect to a center line (CL). 1. Using the diagrams on the next two pages, determine CL1 mounting hole positions. (CL1 is located on the left side of all SNAP rack mounting extrusions.) 2. Use the center-to-center length specification table below to determine the offset between center lines and the number of center line positions for each model. 3. Repeat the process for each center line position.
