DESCRIPTION
The OM5-BP-16-MUX-C 16 channel backpanel (Figure 5) can accept any
of the OM5 analog modules in any mixture.  It can be mounted on the
OMX-1363-C 19-inch metal rack.  The OM5-BP-16-MUX-C has two
analog buses; one for analog input and one for analog output.  This two-
bus configuration takes advantage of the switch controlled outputs on the
input modules and the track-and-hold inputs on the output modules.  A
temperature sensor is mounted on each channel to provide cold junction
compensation for thermocouple input modules (See Figure 6 for
schematic). Field connections are terminated with four screw terminals at
each module site.  Up to four OM5-BP-16-MUX-C backpanels may be
daisy-chained. Use OMX-CAB-01-C cable for daisy chaining and OMX-
1315-XX-C cable for connecting to host computer.
