The program and database information stored in the
Open Processor RAM memory is battery-backed.
This eliminates the need for time-consuming
program and database re-entry in the event of an
extended power failure. When battery replacement
is necessary, the Open Processor illuminates a
“battery low” status LED and can send an alarm
message to selected printers or terminals.
The firmware including the operating system is
stored in non-volatile flash memory. Flash is easily
updateable at the job site. This provides for ease of
upgrade as new firmware updates are made
available.
Brownout protection and power recovery circuitry
protects the Open Processor from power
fluctuations.
Power Open Processors
The Power Open Processor is an updated version of
the Open Processor. It employs state-of-the-art
technology to offer exceptional performance and
memory capacity. It has support for peer-to-peer
communications over industry standard TCP/IP
networks through a direct connection to 10/100
BaseT.
Point Termination Modules
The Point Termination Modules (refer to table)
support one, two, or four points. Modules are
available for analog input or output and digital input
or output point types. Any custom mixture of the
Point Termination Modules can be installed in the
enclosures.
The Point Termination Module consists of two
pieces: the electronic point module and the
termination block, which provides wire or pneumatic
tubing connections. Designed for phased
installation, the electrician wires to all the
termination blocks. The system technician installs
the module electronics during start-up, thereby
protecting electronics from harsh job site conditions.
These modules quickly and easily snap into place
without tools, and without having to re-terminate
wires for fast servicing. Modules can be snapped in
and out without powering down the field panel to
minimize any system downtime.
Each module is supplied with a label insert that is
customized to reflect the actual device connected to
the module. Address keys provide addressing of the
Point Termination Module to the processor and
corresponds to the point address in the database.
