The 1769-OW16 is a compact industrial relay output module designed for PLC-based automation systems requiring flexible AC and DC switching capability.
It provides 16 normally open relay output channels, arranged in 2 groups of 8 points, allowing direct switching of both AC and DC loads without requiring external solid-state devices.
This module is widely used in medium-power control applications where electrical isolation, load flexibility, and reliability are critical.
The Compact I/O series allows scalable expansion of input/output modules in a unified PLC system architecture.
The 1769-OW16 uses mechanical relay contacts to switch electrical loads. Unlike transistor or triac outputs, it provides galvanic isolation through physical contacts, making it suitable for mixed-voltage industrial environments.
Each output channel operates as a normally open contact, allowing switching of both AC and DC circuits up to industrial load levels.
It is commonly used in systems requiring robust switching for motors, solenoids, and control circuits.
