DC Outputs

DC power is typically used for instrumentation or light control circuits. Examples might be solenoid valves, indicator lamps or sinking or sourcing signals to other equipment. These devices are generally two-lead devices as illustrated in Figure 39. Refer to DC Output Module Specifications on page 14 for module details.
