English | SNAP-PAC-RCK4 SNAP PAC 4-Module Mounting Rack |
  |
special-purpose SNAP I/O modules. The SNAP-PAC-RCK4 can be DIN-rail or panel mounted.
This rack works with all SNAP I/O modules on the Opto 22 website. Analog, digital, and serial modules can be mixed on
the rack and placed in any position. (Some serial modules are limited to a maximum of eight on one rack. See module
data sheets for limitations and power requirements.)
Together with I/O modules and a brain or rack-mounted controller, this rack forms an I/O unit that provides distributed
control in a SNAP PAC System. The I/O unit can also be used for PC-based control or as intelligent remote I/O for an
Allen-Bradley MicroLogix PLC or other RSLogix-based system, such as ControlLogix or CompactLogix.
If you need Factory Mutual approval, see the SNAP-PAC-RCK4-FM instead.
Other SNAP PAC racks available:
SNAP-PAC-RCK8 for 8 modules
SNAP-PAC-RCK12 for 12 modules
SNAP-PAC-RCK16 for 16 modules
NOTE: This rack replaces part number SNAP-M16. All brains that mount on a SNAP-M16 can also be mounted on this
rack.
