SNAP PAC Brains

Description

SNAP PAC brains are powerful and versatile I/O and network

communications processors for your SNAP PAC System

brains are designed primarily to work in distributed systems

controlled by a SNAP PAC programmable automation controller, but

SNAP PAC Ethernet brains can also be used as intelligent remote I/O

in an Allen-Bradley

All SNAP PAC brains provide local intelligence that frees the

controller for supervisory tasks. For example, each 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 controller is lost.

SNAP PAC brains can also be used independently for standalone I/O

processing and communication.

SNAP PAC brains use either Ethernet or serial networks.

EB Series Brains

SNAP PAC Ethernet Brains include the SNAP-PAC-EB1 and the

SNAP-PAC-EB2, both with Factory Mutual versions available

(indicated by -FM at the end of the part number). These brains are

identical in their functions and features except that the SNAP-PAC-

EB1 provides high-speed digital functions for use with 4-channel

digital I/O. The SNAP-PAC-EB2 does not offer high-speed digital

functions. For a complete list of brain features, see

Each SNAP PAC EB brain is equipped with two switched Ethernet

network interfaces. Because these interfaces share a single IP

address and act just like an Ethernet switch, SNAP PAC brains can be

installed not only in a standard star configuration, but optionally in

Features

SNAP PAC EB brains communicate over a standard

10/100 Mbps Ethernet network.

SNAP PAC SB brains communicate over an RS-485 serial net-

work, 2-wire or 4-wire, using a binary protocol.

SB Series Brains

The two SNAP PAC Serial Brains are the SNAP-PAC-SB1 and the

SNAP-PAC-SB2. Like the EB brains, the two SB brains are identical

except that the SNAP-PAC-SB1 provides high-speed digital

functions for use with 4-channel digital I/O. The SNAP-PAC-SB2

does not offer high-speed digital functions. See

comparison of brain features.
