Productivity3000 discrete DC I/O modules monitor ON/OFF signals or control devices that switch DC power (12-24 or 24VDC), such as discrete sensors, and small loads such as solenoid valves or lights. Modules are available in input and output models with up to 64 points.
Many applications rely on digital or discrete control devices that transmit and receive ON/OFF signals using DC voltage, such as limit switches and proximity sensors. These devices are used extensively in industrial applications, especially in package handling and conveying systems. For a Productivity3000 PLC CPU to process DC discrete inputs such as these and control devices that require DC ON/OFF signals light stacklights, a DC I/O module is needed.
