Allen-Bradley 1794-OV16 Digital Output Module 16 Sinking

Product Overview

The Allen-Bradley 1794-OV16 is a Flex I/O digital output module. It belongs to the 1794 series. It provides 16 sinking outputs rated at 24 Volts DC. Each channel supports up to 500 mA. The module is open and has an IP20 rating. It mounts on a DIN rail. The part number is 1794-OV16. This module connects field devices to the I/O bus. It allows insertion or removal under power. This saves time and avoids system restarts. The 1794-OV16 uses a terminal base unit like 1794-TB3.

Application Scenarios

This output module suits industrial automation systems. It controls actuators, valves, and indicators. It works in manufacturing, packaging, and material handling. The module communicates via ControlNet, DeviceNet, EtherNet/IP, or Universal Remote I/O. It operates in temperatures from 0 to 55 degrees Celsius. It handles 5 to 95% noncondensing humidity. Extreme environment XT versions are also available.
