Model of Circuits Used to Operate Motors

The signals sent from the DAQ are collected by 2 different circuits that each operate a motor. These circuits each include a SPST (single pole, single switch) relay and a DPDT (double pole, double throw) relay. The output signal from the DAQ triggers the transistor on each relay and switch the relay. Please see the figure below for more detail. For every relay coil seen on the right has connections as seen on the left in figure 20.
