SNAP-PAC-RCK4

Production Specification

The SNAP-PAC-RCK4 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 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.

Need an enclosure with this 4 position rack? See the SNAP-IT-WM4 which includes an I/O mounting rack and a power supply, already wired. You add the I/O processor and the SNAP input and output (I/O) modules needed for your application. This wall-mounted polycarbonate enclosure makes it easy to install Opto 22 I/O where you need it, providing convenience and protection for your SNAP PAC System. Learn more about the SNAP-IT-WM4.

Other SNAP PAC racks available: NOTE: This rack replaces part number SNAP-M16. All brains that mount on a SNAP-M16 can also be mounted on this rack.

Build your system in the SNAP I/O Configurator.

1 Power requirements shown are for a rack, a processor, and a full load of analog modules. Power requirements for SNAP serial and high-density modules are higher. See module data sheets.

2 “I/O Processor” means a SNAP PAC brain or SNAP PAC on-the-rack controller. For compatibility with legacy Opto 22 products, see form #1693, Legacy and Current Product Comparison and Compatibility Charts.

SNAP PAC System Specification Guide

This guide is a comprehensive introduction to the SNAP PAC System. The guide describes the system's four components (software, controllers, brains, and I/O); shows how to build a basic system and how to expand it; and includes installation instructions, wiring diagrams, dimensional drawings, and specifications for parts.

SNAP PAC Racks Data Sheet

SNAP PAC racks mount one SNAP PAC brain or on-the-rack controller, plus up to 4, 8, 12, or 16 SNAP input/output (I/O) modules. Both standard wired controllers and brains and Wired+Wireless models are mounted on these racks.

I/O modules may be analog, digital, or serial modules. All module types can be mixed together on the same rack in any position.
