OBSOLETE SNAP PAC Serial Brain, analog/digital, with high-speed digital functions

Production Specification

NOTE: This product is obsolete and no longer available.

The SNAP-PAC-SB1 brain is an I/O and communications processor for your SNAP PAC System. Designed primarily to work in distributed systems controlled by a SNAP PAC S-series controller, the SNAP-PAC-SB1 provides local intelligence that frees the controller for supervisory tasks.

As an I/O processor, the SNAP PAC brain independently handles functions such as latching, counting, thermocouple linearization, watchdog timers, and PID loop control. These functions continue to work on the brain even if communication with the SNAP PAC controller is lost.

The SNAP-PAC-SB1 brain supports all the SNAP I/O analog and digital input and output modules available on the Opto 22 website. These modules can all be mixed on the same mounting rack and placed in any position on the rack. The brain and modules mount on a SNAP PAC rack, which holds up to 4, 8, 12, or 16 modules.

In addition to I/O processing, the SNAP-PAC-SB1 brain communicates over an RS-485 serial network (2-wire or 4-wire), and multiple SB-series brains can be installed in a multi-drop (daisy-chain) configuration.

The SNAP-PAC-SB1 brain offers high-speed digital functions, including high-speed counting (up to 20 KHz), quadrature counting, pulse generation and measurement, and TPO (time-proportional output). If you do not need high-speed digital functions, choose the SNAP-PAC-SB2 brain instead. For a complete list of features and specifications, see form #1689, the SNAP PAC Brains Data Sheet, under the Documents tab.

SNAP PAC System Specification Guide

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 Brains Data Sheet

NOTE: Due to the unavailability of essential parts, SNAP PAC brains are obsolete and no longer available. Instead of Ethernet-based brains, use a SNAP-PAC-R1 controller/brain; it has all the same features plus additional power (and programmability, if you need it). For serial brain options, contact Opto 22 Product Support. 

SNAP PAC brains are powerful and versatile I/O and network communications processors. Designed primarily to work in distributed systems controlled by a SNAP PAC controller, SNAP PAC Ethernet brains can also be used as intelligent remote I/O for groov EPIC systems and Allen-Bradley Logix-based PLC systems.

SNAP PAC brains provide local intelligence for functions such as latching, counting, thermocouple linearization, watchdog timers, and PID loop control.

This document covers the following SNAP PAC brains:

Firmware for all SNAP PAC products

Firmware for all SNAP PAC products (single download)

See the README document for information on changes and fixes in the current version of this product's firmware.


NOTE: Opto 22 recommends that you always use the most recent release of PAC Manager. Depending on the shipment date or the version number of the firmware currently installed on your SNAP-PAC-R or SNAP-PAC-S controller, older versions of PAC Manager cannot install certain levels of firmware:
  • As of February 22, 2022, some SNAP-PAC-R and SNAP-PAC-S controllers ship with new Ethernet components, along with PAC Firmware R10.4d (or higher) and new bootloader firmware to support the new components. PAC Firmware R10.4d (or higher) will not permit installing firmware lower than R10.4d on these controllers. To update firmware on these controllers, you need PAC Manager R10.4c or higher.
  • Effective April 2, 2018, some SNAP PAC controllers and brains have new flash components. These units shipped with firmware R9.5g (or higher) and new bootloader firmware. PAC firmware versions R9.5f and lower are not compatible with the new component. If you inadvertently install firmware R9.5f or lower on one of these units, you can recover by using the Failsafe Bootloader Mode to install firmware R9.5g or higher.
    • For more information about the new flash component, see KB87213.
    • For details on Failsafe Bootloader Mode, see "Replacing Damaged Firmware" in the PAC Manager User's Guide (form 1704).
  • To install PAC firmware R9.2c or higher on the following controllers only, use PAC Manager R10.4b (or higher), installed by either PAC Project 10.4002 or build 7 of the PAC Manager R10.4b installer. Wireless versions are not affected by this issue:
    • SNAP-PAC-R1
    • SNAP-PAC-R1-B
    • SNAP-PAC-R2
