Figure 9-10. Dual Output Circuits with a Common Ground
Connecting two output circuits with a single power supply
If two output circuits are connected to a single 702 transmitter with a single power supply, both
CH + and CMN terminals must be connected to each output circuit. The negative power supply
wires must be at the same voltage and connected to both CMN terminals.
Figure 9-11. Dual Output Circuits with One Power Supply
Switching greater currents or voltages
It is important to note that the maximum output switching capacity is 26 volts DC and 100
milliamps. If a greater voltage or current is to be switched, an interposing relay circuit can be
used.
Figure 9-12
shows an example of a circuit to switch higher currents or voltages.
