SNAP-PAC-RCK4-FM

Availability: Obsolete
OBSOLETE SNAP PAC 4-Module Mounting Rack

Production Specification

*** NOTE: This part is OBSOLETE and no longer available. ***
Please consider SNAP-PAC-RCK4 or contact Opto 22 Pre-Sales engineers for more information.

The SNAP-PAC-RCK4-FM mounts one SNAP PAC brain or on-the-rack controller and up to 4 analog, digital, serial, and special-purpose SNAP I/O modules. The SNAP-PAC-RCK4-FM 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.

Other SNAP PAC racks available: Build your system in the SNAP I/O Configurator.
