Product Summary
The Allen-Bradley 1794-OV16P Flex I/O module delivers 16 protected sinking outputs for reliable 24V DC control. Its electronic protection shuts down the module during short-circuit or overload events. The unit automatically recovers once you remove the fault condition. This design prevents unnecessary processor interrupts and boosts system uptime. You can install or remove this module under power without rewiring.
Theme Option A: Product Procurement & Buyer Guide
Selecting the Right Protected Output Module
The 1794-OV16P uses protected (P) outputs to guard against electrical faults. This feature shuts down the module during short-circuits or high temperatures. It automatically recovers when you clear the fault condition. This design does not pass fault status to the processor. It saves time and removes system restart inefficiency.
Understanding Key Electrical Ratings
This module provides 16 current sinking outputs with a nominal 24V DC on-state voltage. It supports an on-state voltage range from 10V to 31.2V DC. Each channel delivers a maximum on-state current of 500mA. The total module output current rating is 8.0A. Its maximum off-state leakage is only 0.5mA.
Power Dissipation and Thermal Management
The module dissipates a maximum power of 4.2W at 31.2V DC. It generates up to 14.3 BTU/hr of thermal dissipation. This low power draw reduces heat buildup inside your control panel. It helps maintain stable operating temperatures for adjacent components.
Communication and Network Compatibility
You can integrate this module with ControlNet, DeviceNet, EtherNet/IP, or Universal Remote I/O networks. It draws only 80mA from the FlexBus backplane. This low current consumption leaves ample power for other modules in the chassis.
Compatible Terminal Base Units
The 1794-OV16P works with the 1794-TB3 and 1794-TB3S terminal base units. The 1794-TB3 provides three screw clamp terminal strips for secure wiring. It supports daisy-chaining power to nearby Flex I/O modules.
Extreme Environment Options
XT versions of this module operate in extreme environments. These variants reduce panel and maintenance costs. They are ideal for applications with high temperatures or vibration.
