DC Inputs

DC Input modules are designed to operate with either sinking or sourcing devices. They are typically used with proximity sensors and other solid-state devices. (Figure 36) Input modules may need to be installed relatively close to the sensor location. Refer to DC Input Module Specifications on page 9 for module details.
