this is the air or gas controller card from a computer controller frame that has all std buss connected cards. Main winsystems computer mainboard. THIS CARD containsEight BURR-BROWN INA128 precision op amps for strain guage applications. best i can tell is that they are pressure transducers for each of the 8 pneumatic outputs so the action of each of 4 valves can be regulated. Card is a 980-2300 series per silkscreen. Also marked P/N 681-0181-009 Probably a P-E number. Input and output tubing manifold is included connects to 1/16 ID tube. Operating elements of card are 2 LM339 quad comparators , eight pots and leds that interconnect to those lm339's, One octal tri state buffer that i believe is used to drive the card from the digital input commands from the buss, the eight other pots by the op amps are preset to null out the pressure transducers. More info may be available from robitech by writing them. If interested in any of the other cards you can contact me for what you may want. it was for a setup using a laser to fire on selected areas of targets and change the parts as they were completed. It does have a large amount of high precision analog to digital converter chips and other ttl/cmos items as well as a processor board. board was used with 24 volt supply and the IMS drivers have a rating of 48 volt 3 amp i
