The 1769-OW16 (Part Number: 1769-OW16) is a high-density digital relay output module designed for the Allen-Bradley CompactLogix and MicroLogix 1500 systems. This module provides sixteen normally open (N.O.) relay contacts, organized into two isolated groups of eight points each. By utilizing mechanical relay outputs, the 1769-OW16 offers the versatility to switch both AC and DC loads, making it an ideal interface for controlling solenoids, motor starters, and indicators across diverse voltage ranges.
Engineered for industrial reliability, this module features zero off-state leakage current and a robust thermal design. It is compatible with local controller chassis or can be used as distributed I/O through 1769-AENTR or 1769-ADN adapters. To ensure system stability, the module includes a power supply distance rating of eight, meaning it must be located within eight slots of a compatible 1769 power supply.

The 1769-OW16 is widely used in:
Material handling
HVAC control
General factory automation
Its ability to handle up to 240V AC makes it particularly suitable for:
Interposing relay logic
Controlling high-wattage signaling devices
Can this module switch different voltages on the same module?
Yes. Because the module is divided into two isolated groups of eight, you can switch one voltage (e.g., 24V DC) on the first group and a different voltage (e.g., 120V AC) on the second group.
Does the 1769-OW16 require a separate power supply?
When used in a CompactLogix or expansion bank, it must be powered by a 1769-series power supply. However, if it is connected directly to a MicroLogix 1500 base unit, it can draw power through the base connector.
