This guide is a comprehensive introduction to the SNAP PAC System. The guide describes the system's components (software, controllers, I/O processors, 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 mount one SNAP PAC brain or on-the-rack controller, plus up to 4, 8, 12, or 16 SNAP input/output (I/O) modules.
I/O modules may be analog, digital, or serial modules. All module types can be mixed together on the same rack in any position.
This data sheet covers the following part numbers:
