Information About 1794-OB16
The Allen-Bradley 1794-OB16 Flex I/O module provides sixteen 24V DC sourcing digital outputs designed for fast, reliable switching in industrial control systems. Its 1 ms response time makes it suitable for high-speed discrete operations, while its 0.5 A per-channel current rating supports a wide range of loads including solenoids, lamps, and relays. The module mounts on standard Flex I/O terminal bases and integrates seamlessly with FLEXBus architecture, ensuring streamlined installation and modular expansion. Engineered for in-cabinet use, it features open-style construction, screw-terminal connectivity, and robust electrical protection to ensure stable operation in demanding environments.
Key Features:
- Sixteen 24V DC sourcing outputs: supports distributed control architectures requiring high channel density with independent switching capability for each output.
- High current capability per channel: each output drives up to 500 mA with a combined module capacity of 8 A, making it suitable for solenoids, pilot lights, and other industrial loads.
- Fast 1 ms response time: ensures accurate and timely switching for motion systems, machine sequencing, and discrete event control.
- Wide operating voltage range: supports 10–31.2V DC input levels with minimal 0.5V drop to maintain compatibility with diverse field devices.
- Built-in surge and overload handling: each channel supports 2 A surge for 50 ms every 2 seconds, improving durability with inductive loads.
- Low off-state leakage: maximum 0.5 mA leakage prevents unintended activation of sensitive loads.
- Compatible with multiple terminal bases: works with 1794-TB2, TB3, TB3S, TB3K, and TB3SK, providing flexibility in wiring and panel layout.
- FlexBus-powered electronics: consumes only 80 mA from the 5V DC backplane, enabling efficient integration in large Flex I/O systems.
- Robust environmental and certification profile: supports 0–55°C operation and meets major global industrial certifications for wide deployment flexibility.
The 1794-OB16 delivers the reliability and precision required for high-density 24V DC digital output applications across distributed Flex I/O control systems.
