Frequently Asked Questions about 1794-OA16
Question: What is the purpose of the 1794-OA16 module?
Date Update:12/06/2025
Answer:

The Allen-Bradley 1794-OA16 is a digital AC output module used in FLEX I/O systems to control field devices such as relays, contactors, pilot lights, and alarms. It is designed to operate AC loads within a voltage range of 74 to 132 VAC, making it suitable for typical 120V AC industrial devices. It is widely used in distributed control systems where multiple remote outputs need to be switched. Its compact size and compatibility with various terminal bases allow flexible installation. This module enhances the scalability and modularity of industrial control architectures.

Question: What voltage and current ranges does it support?
Date Update:12/06/2025
Answer:

Each channel of the 1794-OA16 supports an ON-state voltage range of 74 to 132 VAC at 47–63 Hz. The minimum ON-state current per output is 5 mA, while the maximum continuous current is 0.5 A. The total module current rating is 4 A. The ON-state voltage drop is a maximum of 1.5V at 0.5 A, and the off-state leakage current is up to 2.25 mA. This makes the module suitable for standard AC control circuits.

Question: What environment is it rated for?
Date Update:12/06/2025
Answer:

The module operates in temperatures from 0 to 55°C (32 to 131°F) and can be stored between -40 to 85°C (-40 to 185°F). It supports relative humidity of 5–95%, non-condensing. Its shock rating is 30G (operating) and 50G (non-operating), with vibration resistance of 5g at 10–500 Hz. It must be installed in a clean, dry control cabinet due to its open-type enclosure.

Question: How is the module mounted?
Date Update:12/06/2025
Answer:

The 1794-OA16 is DIN rail mountable and requires a terminal base for connection. Supported bases include 1794-TBN, TBNF, TB2, TB3, TB3S, TBKD, TBNK, and others. These bases provide wiring access and define wire size limits. The module snaps into the terminal base, which simplifies both installation and removal. This modular design is intended for quick deployment in field cabinets.

Question: Is the module still being manufactured?
Date Update:12/06/2025
Answer:

Yes, as of now, the 1794-OA16 is still an active product in the Rockwell Automation catalog. It remains a common component in distributed I/O systems using the Flex I/O platform. However, availability should always be confirmed through official channels. Its popularity stems from its reliability and broad compatibility with terminal bases and adapters.
