Analog input & digital expansion card for Micro PC The 5710 card provides a versatile platform for mixed analog/digital environments. With 16 analog input chan- nels 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 Octagon products are designed and per–channel basis. The analog output also has manufactured under the supervision of an ISO 9001–2000 certified adjustable ranges, from –5V to +10V. Strict isolation quality management system. 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 The 5710 will withstand high shock and vibration, and counter/timer operation. An example of one of these operates in temperature ranges from –40° to +85° C. modes is autoconvert, which is a method of starting a This rugged expansion card will provide years of reli- conversion at a regular interval.

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 programma- Features ble and must be initialized by the control program.

You can use 12 to 22 gauge solid ORDERING INFORMATION or stranded wire to connect equipment to the screw ter- #3181 5710 analog & digital I/O card minals. 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 inter- face. Medium–voltage logic, up to 28V, is used to con- vert 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 provid- ing 4000V of isolation between the high–voltage sys- tems and the 5710. 33 6510 W. 91st Avenue • Westminster CO 80031 • 303–430–1500 6510 W. 91st Avenue • Westminster CO 80031 • 303–430–1500 www.octagonsystems.com www.octagonsystems.com
