This document compares features of SNAP PAC hardware controllers (SNAP PAC S-series and R-series) and SNAP PAC brains, all part of the SNAP PAC System.

NOTE: Due to the unavailability of essential parts, all SNAP PAC brains are obsolete and no longer available. Use rack-mounted controllers instead of Ethernet-based brains. For serial brain options, contact Opto 22 Product Support.
