When a Packaging Line Stalls, Every Minute Counts
A plant engineer calls at 6 a.m. A MicroLogix-controlled packaging line has stopped because an output module failed. Production is down, and the replacement must arrive before the next shift. That scenario is exactly why the Allen-Bradley 1762-OW16 matters. This MicroLogix expansion module adds sixteen AC/DC relay output channels to MicroLogix 1100, 1200, and 1400 controllers, letting one PLC drive more loads without a full system redesign.
Oil AutoTech stocks spares like this for oil, gas, and industrial automation teams that cannot wait. Fast dispatch, worldwide.
What the 1762-OW16 Actually Does
The 1762-OW16 is a relay output expansion module in the MicroLogix series. It energizes and de-energizes electrical loads through sixteen relay contact outputs. Two isolated groups of eight channels each keep wiring organized: Group 0 covers outputs 0–7, and Group 1 covers outputs 8–15. Each point handles up to 2.5 A continuous current, with 8 A per common and 16 A per module. A 10 ms signal delay applies to both ON-to-OFF and OFF-to-ON transitions.

Where This Module Earns Its Place
In oil and gas terminals, the 1762-OW16 switches pilot valves, alarms, and indicator lamps across wide voltage ranges. Its AC/DC relay contacts handle mixed loads on one module, which simplifies panel design. In water treatment and packaging, the sixteen channels consolidate motor starters, solenoids, and signal beacons into a single expansion slot. For retrofit projects, the wide 5–265 V AC and 5–125 V DC operating range means the same module works across legacy and modern control voltages.
Installation and Integration Notes
The module mounts on DIN rail or directly to a panel, depending on the base controller. When paired with a MicroLogix 1100, up to four modules are supported; a MicroLogix 1200 accepts up to six; a MicroLogix 1500 accepts seven. Install surge suppressors across inductive loads to protect relay contacts from high inrush current and extend service life. Follow Allen-Bradley wiring guidelines, and guard against electrostatic discharge, which can damage the module’s semiconductors.
Selection Checklist Before You Order
Confirm your controller model and available expansion slots first. Verify the load voltage falls within the 5–265 V AC or 5–125 V DC range, and check that per-point current stays at or below 2.5 A. For inductive loads, plan surge suppression at the load. If you need hands-on selection help, the Oil AutoTech team can match the 1762-OW16 to your existing MicroLogix setup.
