Key Technical Specifications

• Brand and Model: Allen-Bradley 1794-OV16P Flex I/O Digital Sinking Output Module with protection.
• Output Configuration: 16 protected sinking outputs with 24V DC nominal voltage (operating range 10-31.2V DC).
• Current Ratings: 8.0A total per module; 500mA maximum per channel with electronic current limiting.
• Electrical Characteristics: 0.2V DC max on-state voltage drop; 0.5mA max off-state leakage.
• Switching Speed: 0.5 ms max off-to-on delay; 1.0 ms max on-to-off delay.
• Power & Isolation: Draws 80mA from FlexBus @ 5V DC; dissipates 4.2W (14.3 BTU/hr) max at 31.2V DC.
• Environmental Tolerance: Operates at 0 to 55 °C (32-131 °F) with 5-95% noncondensing humidity.
• Protection Features: Automatic shutdown on short-circuit, overload, or overtemperature; auto-recovery after fault removal.
• Status Indication: 16 yellow LEDs clearly show channel output states for easy diagnostics.

Frequently Asked Questions (FAQ)

• What makes the 1794-OV16P different from the standard 1794-OV16?
  The 1794-OV16P includes electronic output protection that automatically shuts down channels during short-circuit, overload, or overtemperature conditions and recovers automatically when you remove the fault.
• What is the maximum on-state voltage drop for the 1794-OV16P?
  The maximum on-state voltage drop is only 0.2V DC at full load, ensuring efficient operation and minimal heat generation.
• Can I use this module with 12V DC systems?
  Yes, the 1794-OV16P operates from 10 to 31.2V DC, so it works perfectly with both 12V and 24V DC control voltages.
• What network adapters are compatible with the 1794-OV16P?
  You can connect it to any 1794-series Flex I/O adapter, including those for EtherNet/IP, ControlNet, DeviceNet, and Universal Remote I/O.
• Does the module automatically reset after a fault?
  Yes, the 1794-OV16P automatically recovers normal operation once you remove the overload or short-circuit condition, without requiring processor intervention.
• Does the module come with a terminal base?
  The package includes only the 1794-OV16P module. You need to order the terminal base (e.g., 1794-TB3) separately.
• How fast do you ship the 1794-OV16P?
  We dispatch within 5 working days via FedEx, UPS, or DHL, depending on your location.
