NOTE: This rack is not suitable for SNAP PAC brains and rack-mounted controllers; see the SNAP-PAC-RCK4.
The SNAP-B4M rack mounts a compatible SNAP brain (such as the serial B3000 or the SNAP-UP1-ADS) and four SNAP I/O modules. Analog, digital, and serial modules can be mixed on the same rack. 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 and requires a 5 VDC power source.
