The TS-15110 is a 4-channel analog output module. Each channel of the TS-15110 has an AO terminal and a common terminal (COM). COM terminals are internally connected to the isolated ground reference of the module. You can connect a load to each channel of the TS-15110. Connect the positive lead of the load to the AO terminal, and the ground of the load to the corresponding COM terminal. Refer to the following figure for an illustration of connecting a load to the TS-15110.

Each channel has a digital-to-analog converter (DAC) that produces a voltage signal. Each channel also has overvoltage and short-circuit protection. Refer to the module specifications for more information about the overvoltage and short-circuit protection. Refer to the following figure for an illustration of the output circuitry for one channel of the TS-15110.

When the module powers on, the channels output the startup voltage. Refer to the module specifications for more information about startup voltage. Refer to the NI-DAQmx Help for information about configuring startup output states in software.
