Allen-Bradley 1756-OB16E 16-Point Digital Output Module

The Allen-Bradley 1756-OB16E 16-Point Digital Output Module provides sixteen 24V DC sourcing outputs for ControlLogix PLC systems, enabling reliable actuation of solenoids, relays, contactors, and indicator devices in high-performance industrial automation. It is commonly installed in control panels for automotive assembly lines, packaging machinery, conveyors, and process control equipment, and maintenance teams and system integrators use this module for output expansion, system upgrades, panel retrofits, and the replacement of failed digital output modules within ControlLogix-based architectures. Technical specifications include 16 outputs with 24V DC sourcing (PNP) capability, a maximum of 2 A per point, backplane current draw of 250 mA at 5.1 V DC, channel-to-channel isolation, and a typical 1 ms response time; mounting is in a ControlLogix chassis with an operating temperature range of 0°C to 60°C. Common replacements for this module are the Allen-Bradley 1756-OB16D, 1756-OB16I, and 1756-OB32E.
