Allen-Bradley 1794-OV16 FLEX I/O 16-Point 24VDC Sinking Output Module
The 1794-OV16 is an Allen-Bradley FLEX I/O discrete output module that provides 16 current-sinking channels for 24 VDC industrial automation systems. Housed in an IP20 open-style enclosure designed for DIN rail mounting, it serves as a reliable interface for driving field devices in distributed I/O configurations.
Sinking Output Operations and Load Switching
The module controls up to 16 separate DC loads by sinking current to the DC common return line at a nominal operating voltage of 24 VDC. This configuration is standard for interfacing with industrial field components such as solenoids, pilot lights, small relay coils, and control actuators that draw power from an external supply.
Architecture and Modular Installation
As an integral part of the FLEX I/O system, the module mounts directly onto a compatible terminal base unit. This modular design separates the field wiring connections from the I/O electronics, enabling quick module removal and replacement without requiring wires to be disconnected or re-terminated during maintenance.

Frequently Asked Questions
Q: What is the main difference between the 1794-OV16 and the 1794-OV16P? A: The standard 1794-OV16 relies on external fusing or circuit design for overcurrent protection, whereas the 1794-OV16P includes built-in electronic short-circuit protection.
Q: How is the 1794-OV16 wired to field loads? A: The module snaps onto a standard FLEX I/O terminal base unit, where field wiring is connected directly to the terminal base block rather than to the module body itself.
