DATA SHEET Form 0784-190731 PAGE 1 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 Rack DESCRIPTION NOTE: For racks to use with SNAP PAC controllers and brains, see Opto 22 form #1684, the SNAP PAC Racks Data Sheet. NOTE: M-series racks (such as the SNAP-M64), used with SNAP Simple brains and SNAP-UP1-M64 controllers, have been replaced by SNAP PAC racks.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 B-series mounting racks are designed to hold an intelligent SNAP I/O processor--either a SNAP brain or an on-the-rack controller--and several I/O modules. All SNAP racks offer panel mounting and the option of DIN-rail mounting. SNAP racks require a 5 VDC power source. SNAP-B4M, SNAP-B8M, SNAP-B12M, SNAP-B16M, and SNAP-D64RS racks are Factory Mutual approved. Part Numbers 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 Ethernet-based 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 B-series 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. 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. MC and MC-P model racks provide an auxiliary screw-type terminal strip for field wiring common connections such as loop power distribution. MC racks use a fixed terminal strip, while MC-P racks use removable connectors for easy maintenance (see enlarged view on the following page).

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).

DATA SHEET Form 0784-190731 PAGE 9 MOUNTING NOTE: If you are not using hold-down screws, the SNAP rack assembly should be mounted horizontally. Alternate Method: Prefabrication of Panels Use the following steps to mount racks as shown in the diagrams on the next two pages. 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. Preferred Method: Template (Product on site) 1. Use SNAP rack mounting extrusion as template. 2. Be sure to use the diagrams on the next two pages to determine required product and option clearances.

More about Opto 22 PRODUCTS * Opto 22 develops and manufactures reliable, easy-to-use, open standards-based hardware and software products. Industrial automation, process control, building automation, industrial refrigeration, remote monitoring, data acquisition, and industrial internet of things (IIoT) applications worldwide all rely on Opto 22. groov EPIC(R) System Opto 22's groov Edge Programmable Industrial Controller (EPIC) system is the culmination of over 40 years of experience in designing products for the automation industry. groov EPIC gives you an industrially hardened system with guaranteed-for-life I/O, a flexible Linux(R)-based controller with gateway functions, and software for your IIoT application or any application. groov EPIC I/O Ignition Edge(R) from Inductive Automation(R), with OPC-UA drivers to Allen-Bradley(R), Siemens(R), and other control systems, and MQTT/Sparkplug communications for efficient IIoT data transfer groov Edge Appliance Visualization, data handling, and connectivity in a compact, industrial box: that's the groov Edge Appliance. Included are: * groov View for building and viewing operator interfaces on PCs and mobile * Node-RED for building simple logic flows * Ignition Edge from Inductive Automation, for OPC-UA drivers and MQTT/Sparkplug IIoT communications Older products From solid state relays (our first products) to world-famous G4 and SNAP I/O, to SNAP PAC controllers, Opto 22 products last a long time. You can count on us to give you the reliability and service you expect. I/O provides the local connection to sensors and equipment. groov I/O offers up to 24 channels on each I/O module, with a spring-clamp terminal strip, integrated wireway, and swingaway cover. QUALITY Founded in 1974, Opto 22 has established a worldwide reputation for high-quality products. All are made in the U.S.A. at our manufacturing facility in Temecula, California. Opto 22 I/O is so reliable, we can afford to guarantee it for life. groov I/O is hot swappable, UL Hazardous Locations approved, and ATEX compliant. Because we test each product twice before it leaves our factory rather than testing a sample of each batch, we can guarantee most solid-state relays and optically isolated I/O modules for life. groov EPIC Controller The heart of the system is the groov EPIC controller. It handles a wide range of digital, analog, and serial functions for data collection, remote monitoring, process control, and discrete and hybrid manufacturing. In addition, the EPIC provides secure data communications among physical assets, control systems, software applications, online services, and more, both on premises and in the cloud. Configuring and troubleshooting I/O and networking is easier with the EPIC's integrated high-resolution touchscreen. Authorized users can see your groov View HMI locally on the touchscreen or on a monitor connected via the HDMI or USB ports. groov EPIC Software Software includes: * Flowchart-based PAC Control for control programming, or build your own custom application with optional secure shell access * groov View for building and viewing your own deviceindependent HMI * Node-RED for creating simple logic flows from pre-built nodes OPTO 22 * www.opto22.com 43044 Business Park Dr. Temecula, CA 92590-3614 FREE PRODUCT SUPPORT Opto 22's California-based Product Support Group offers free, comprehensive technical support for Opto 22 products from engineers with decades of training and experience.
