Product Summary
The Allen-Bradley 1794-OB16 delivers sixteen reliable 24VDC sourcing outputs for distributed control. This module controls actuators and indicators with precision. Its robust design withstands harsh industrial environments and high vibration. Engineers trust this module for consistent performance.
Product Procurement & Buyer Guide
Procurement managers must verify the 1794-OB16 matches their system voltage. This module requires a nominal 24VDC supply. It accepts a range from 10VDC to 31.2VDC. Each of the sixteen channels sources up to 500mA. The total output current rating reaches 8.0A. This module works with terminal bases like the 1794-TB3. The 1794-TB3 provides three screw clamp terminal strips. It supports daisy-chaining for power distribution. You can install up to eight modules in one rack. This allows for 128 total outputs in a single system.
Application engineers should note the module’s electrical isolation. The 1794-OB16 provides 50V continuous isolation between channels. It also passes a 850VDC dielectric test for one second. This protects your system from voltage transients. The module draws only 80mA from the 5VDC FlexBus. Its maximum power dissipation is 5.3W at full load. This low heat output simplifies cabinet cooling requirements. The module carries global certifications including CE, c-UL-us, and TÜV. This ensures compliance with international safety standards.
Expert Technical Evaluation & Performance Review
The 1794-OB16 delivers fast and clean signal switching. The off-to-on delay is just 0.5 milliseconds. The on-to-off delay takes only 1.0 millisecond. This speed is critical for precise machine control sequences. The module’s on-state voltage drop stays below 0.5VDC. This minimizes power loss and heat generation. The off-state leakage current is a mere 0.5mA. This prevents false triggering of sensitive loads.
Environmental tolerances are a key strength of this module. It operates reliably from 0 to 55 °C. You can store it from -40 to 85 °C. The module handles 30g of operational shock. It withstands 5g of vibration from 10 to 500 Hz. These ratings make it suitable for mobile equipment and heavy machinery. The module features sixteen yellow LED indicators. These provide immediate visual status for each output channel. This simplifies troubleshooting and reduces downtime. The module uses a keyswitch position 2 for physical alignment. This prevents incorrect module installation in the rack.
