SNAP-B12M Snap B-Series 12 Module Rack, 5.0 to 5.2 VDC at 3.4 Amps Max

The SNAP-B12M rack mounts a compatible SNAP brain (such as the serial B3000 or the SNAP-UP1-ADS) and 12 SNAP I/O modules. Analog, digital, and serial modules can be mixed on the same rack. Four-channel digital modules can be placed in the first eight positions only; 32-channel digital modules can be placed in any position. Field devices are wired directly to the top-mounted removable connectors on the SNAP I/O modules. The rack can be panel mounted or DIN-rail mounted. It requires a 5 VDC power source. 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. This rack family includes racks that are compatible with ARCNET and serial SNAP brains, including those using Modbus and Profibus protocols, and with some Ethernet-based SNAP Ultimate I/O on-the-rack controllers and SNAP Ethernet I/O brains. For specific processor compatibility. 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. 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" standard machine screws to hold each module in position.Underwriters Laboratory, Factory Mutual, IEC 950: 1991-09, 89/336/EEC, 2002/95/EC, Defense Federal Acquisition Regulation Supplement
