Simultaneous Analog Input Configuration

The signal source for each GPIC simultaneous analog input is selected with a series of DIP switches. Because all input signals are differential, a pair of contacts should be closed to select one signal source. Refer to the following table for information about selecting simultaneous sampled analog input signal source.

Notice Only one signal source should be connected to each GPIC analog input at one time. Connecting two signal sources in parallel can produce unexpected results.

Analog inputs from inverters are shared between the half-bridge modules and the full-bridge modules. For proper operation, each analog line should be driven by only one inverter. Refer to Inverter Signals for more information.
