SNAP-PAC-SB2

Production Specification

The SNAP-PAC-SB2 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-SB2 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-SB2 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-SB2 brain does not offer high-speed digital functions; if you need high-speed counting (up to 20 KHz), quadrature counting, pulse measurement, and frequency and period measurement, choose the SNAP-PAC-SB1 brain instead. For a complete list of features and specifications, see form #1689, the SNAP PAC Brains Data Sheet, under the Docs & Downloads tab.

See a comparison chart for SNAP PAC controllers and brains.

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 Brains Data Sheet

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 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.
