OPT-SNAP-PAC-EB1-FM

SNAP-PAC-EB1-FM SNAP PAC Ethernet Brain, analog/digital/serial, with high-speed digital functions, Factory Mutual approved

The SNAP-PAC-EB1-FM brain is an I/O and communications processor for your control system. Designed primarily to
work in distributed systems controlled by a SNAP PAC S-series or R-series controller, the SNAP-PAC-EB1-FM can also be
used as intelligent remote I/O with Allen-Bradley industrial PLC systems. The SNAP-PAC-EB1-FM provides local
intelligence that frees the controller (PAC or PLC) for supervisory tasks.
 
NOTE: The SNAP-PAC-EB1-FM offers the same functions as the SNAP-PAC-EB1 brain but is Factory Mutual approved
(U.S. and Canada). If you do not need FM approval, see the SNAP-PAC-EB1.
 
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 controller is lost.
 
The SNAP-PAC-EB1-FM brain supports all the SNAP I/O analog, digital, and serial 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 brain communicates over a standard 10/100 Mbps Ethernet network. The
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 in a multi-drop (daisy-chain) configuration,
extending the control network without the added expense of additional Ethernet network hardware. SNAP PAC brains
can also be installed in a star configuration using standard, off-the-shelf Ethernet network components.
 
The SNAP-PAC-EB1-FM brain supports communication using multiple protocols running simultaneously over Ethernet.
Most customers use the PAC Project software suite for control, monitoring, and data acquisition. At the same time, you
can communicate using other methods, including EtherNet/IP, Modbus/TCP, SNMP, SMTP, FTP, and OptoMMP.
Communication with OPC 2.0-compliant clients is available through OptoOPCServer.
 
The SNAP-PAC-EB1-FM brain offers high-speed digital functions, including high-speed counting (up to 20 KHz, depending
on the module), quadrature counting, pulse generation and measurement, and TPO (time-proportional output). Pulse
generation and measurement require PAC Control and a SNAP PAC controller, or using the brain with Allen-Bradley PLC
systems.
 
If you do not need high-speed digital functions, choose the SNAP-PAC-EB2-FM brain instead.
