Allen-Bradley 1756-OB16E Digital Output Module

The Allen-Bradley 1756-OB16E is a 16-point digital output module for ControlLogix that provides 24V DC sourcing outputs for discrete automation tasks. It delivers 16 sourcing (PNP) outputs with up to 2 A per point, features channel-to-channel isolation, and draws 250 mA from the backplane at 5.1 V; typical response time is 1 ms. Mount it in a ControlLogix chassis and operate it from 0°C to 60°C for fast actuation of field devices like solenoids, relays, and indicator lights. Common applications include automotive assembly lines, packaging machines, material handling systems, conveyors, robotic cells, bottling lines, and manufacturing process equipment requiring reliable DC output control; common replacements are 1756-OB16D and 1756-OB16I.
