5710

5710
Analog input & digital expansion
card for Micro PC
The 5710 card provides a versatile platform for mixed
analog/digital environments. With 16 analog input channels and 19 digital I/O channels, it can monitor and
control a wide variety of conditions simultaneously.
Two D/A output channels control the most sensitive
equipment.
The analog input channels provide 12–bit resolution for
up to 70,000 samples per second. Adjustable full–scale
readings allow measurements from ±50 mV to ±5V, on a
per–channel basis. The analog output also has
adjustable ranges, from –5V to +10V. Strict isolation
ensures that spurious noise does not interfere with the
signals. 19 TTL digital I/O lines complete the package of
I/O in this compact card.
An 82C54 counter timer chip provides six modes of
counter/timer operation. An example of one of these
modes is autoconvert, which is a method of starting a
conversion at a regular interval. The control program
must read the data after the conversion is complete and
change channels if necessary. CTC0 and CTC1 are used
to generate a timed interval for the autoconvert feature.
CTC0 divides a 4 MHz oscillator output. The divide
ratio and countdown function are software programmable and must be initialized by the control program.
Micro PC cards plug into any ISA expansion slot or
Micro PC card cage. The Octagon family of Micro PC
controllers, expansion cards, and card cages provide a
complete solution for applications in transportation,
security, military, communications, distributed control,
point–of–sale, ticketing machines, weighing equipment,
and other similar applications.

Octagon products are designed and
manufactured under the supervision
of an ISO 9001–2000 certified
quality management system.
The 5710 will withstand high shock and vibration, and
operates in temperature ranges from –40° to +85° C.
This rugged expansion card will provide years of reliable service in the most challenging environments.

Typical Configurations
Several terminal boards are available for a 5710 analog
I/O expansion card. The 5B analog module rack is an
industry–standard rack with the capability of measuring
thermocouples, strain gauges, voltage, and currents with
up to 1500V of isolation. You can also control current
output with a 5B module.
The ATB–20 analog terminal board provides a connection for field wiring. You can use 12 to 22 gauge solid
or stranded wire to connect equipment to the screw terminals. The screw terminals bring the lines from the
5710 card out to the terminal board. Connection from
the 5710 to the ATB–20 is one to one.
For applications requiring medium voltage inputs or
outputs, the ITB–8/16 or ITB–16/8 level conversion
board provides a medium–voltage, high–current interface. Medium–voltage logic, up to 28V, is used to convert these voltage levels to TTL levels used by the 5710.
You can connect lamps, small solenoids and relays.
An STB–20 or STB–26 is a terminal board for the digital
I/O lines. When heavy–duty loads and inputs (up to 3A
and 260V AC or DC) are required, the 5710 digital I/O
lines can interface with the MPB series opto module
racks. The opto modules have the advantage of providing 4000V of isolation between the high–voltage systems and the 5710.
