Bridge completion
circuits
Each of the four I/O option card slots on the I/O Carrier module
provides support for up to three bridge completion resistors as well as
a shunt calibration resistor. The bridge completion resistors can be
installed into sockets on the I/O Carrier printed wiring board. The
shunt calibration resistor sockets are accessible from the I/O Carrier
front panel.
The following figures show three typical bridge configurations for a
DC conditioner installed on an I/O Carrier module.
