Allen-Bradley 1762-OB16 DC Source Output Module

The Allen-Bradley 1762-OB16 is a 16-point 24 VDC source output module that provides discrete sourcing outputs for driving field devices such as lights, relays, solenoids, and actuators from MicroLogix and SLC-500 PLC racks. It offers 16 positive-switching (sourcing) outputs that source current from a 24 V DC load supply to field devices via backplane connection to the PLC rack, enabling reliable actuation in automation panels. This module is designed for rack or panel mounting and is commonly used for I/O expansions, retrofit upgrades, or replacing failed output modules in control cabinets. Typical applications include manufacturing lines, conveyors, packaging machinery, water and wastewater facilities, HVAC control panels, and material handling systems where discrete output signaling is essential.
