OPTO 22 SNAP-PAC-RCK4 输入/输出模块
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. Since SNAP analog, digital, and serial I/O modules 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 removable 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 Datasheet, 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 and off the mounting rack.
