As a vital component of the 1762 MicroLogix Expansion I\/O series, this module offers 16 discrete output points, providing engineers with the flexibility to interface control logic with a wide array of field-level electrical loads. By utilizing mechanical relay outputs, the 1762-OW16 ensures complete galvanic isolation between the controller’s logic circuitry and high-voltage field devices, which is essential for protecting the integrity of the control system in harsh industrial environments.\u003c\/p\u003e\n\u003cp\u003eThis module is designed for versatility, supporting both AC and DC switching voltages across a range of 5V to 265V AC or 5V to 125V DC. With two isolated groups of eight outputs each, it allows for the simultaneous management of disparate voltage domains on a single module—a common requirement in complex machine control applications. Whether you are driving contactors, solenoid valves, pilot indicators, or intermediate relays, the 1762-OW16 delivers reliable performance and robust signal switching. Its compact design and DIN-rail or panel-mount capability make it an optimal choice for space-constrained industrial cabinets where reliability and long-term durability are not optional.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr
