MTL4763Pac FOR STRAIN-GAUGE BRIDGES.

The MTL4763Pac is a triple 2-channel barrier designed for strain-gauge bridge applications with IIC gas groups, for which function it combines the circuits of one MTL766Pac and two MTL761Pac units. Channels 1 and 2 (equivalent to the MTL766Pac) supply power to the bridge while channels 3 and 4 (equivalent to one MTL761Pac) interface with the sensing circuit and channels 5 and 6 (equivalent to the other MTL761Pac) interface with the pick-off circuit. As channels 3 to 6 are identical in specification, the functions of channel pairs 3 and 4 and 5 and 6 are interchangeable; ie. channels 3 and 4 can be used for the output, while channels 5 and 6 can be used to sense the supply. 

The MTL4763Pac is normally intended to be used on general-purpose backplanes. If used on a bussed-power backplane, channels 5 and 6 cannot be used, because, on this type of backplane, module base connections pins 13 and 14 are not accessible.
