PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-OV16P is a FLEX I/O Sink Output Module providing 16 protected current-sinking DC outputs. It operates at 24V DC nominal voltage and delivers up to 500mA per channel. Total aggregate module current reaches 8.0A across all channels. Electronic protection automatically shuts down a channel during short-circuit, overload, or thermal fault conditions. Normal operation resumes automatically once the fault condition clears.
This module mounts directly onto compatible terminal base units including the 1794-TB3 and 1794-TB3S. Modular terminal base construction allows removal and insertion under power without disturbing field wiring. Sixteen yellow LED indicators give immediate visual verification of individual output channel states. FLEX I/O adapters support communication across EtherNet/IP, ControlNet, DeviceNet, and Universal Remote I/O networks.
