The Allen-Bradley 1760-L12DWD-ND is a 12-volt DC Pico controller from the Rockwell Automation 1760 Pico Controllers series, designed for compact and efficient industrial control applications. It features eight DC inputs, four relay outputs, and a real-time clock, without an integrated display screen. The controller has a nominal power dissipation of 2 watts and a nominal current rating of 140 milliamps at 12 volts DC. Its inputs are electrically isolated from the outputs but not from the power supply or from each other, ensuring safe and reliable operation within automation systems.
