Digital Output Modules | Allen-Bradley 1794-OV16 FLEX I/O

The Allen-Bradley 1794-OV16 is a 16-point discrete output module in the FLEX I/O product family. It provides 24 VDC sinking outputs for PLC-controlled field devices and uses an open-style design for DIN rail mounting. Its IP20 rating identifies the enclosure protection level, while its compact 0.16 kg module weight supports equipment identification and handling.

Technical Specifications

Output Configuration

The 1794-OV16 provides 16 discrete output points for controlling external field devices through a FLEX I/O system. Its sinking output configuration determines the output current path: the module switches the connected load toward the DC common reference when an output is activated.

This configuration must be matched with the field wiring and load arrangement. Confirm the connected device's voltage, polarity, and current requirements before selecting the module for an application.

Installation and Physical Design

The module features an open-style construction and DIN rail mounting. Its IP20 protection rating indicates protection against access to hazardous parts by fingers and against solid foreign objects of 12.5 mm or larger. It is intended for installation within an appropriately designed control enclosure rather than direct exposure to environmental conditions.

Warranty Information

The supplied product information states that the original factory warranty does not apply and that a Radwell 2-year warranty is included. This warranty statement relates to the supplied sales listing and should not be interpreted as an Allen-Bradley manufacturer warranty.
