PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-OV16 is a FLEX I/O digital output module designed for distributed industrial control. It mounts directly onto a compatible terminal base unit without requiring direct field wiring on the module itself. This design enables removal and insertion under power during operational maintenance routines.
The module provides 16 current sinking output channels rated for 24 Volts DC nominal operation. It supports an operating voltage range from 10 to 31.2 Volts DC for diverse field loads. Individual channel status indicators display operational feedback for maintenance monitoring across the terminal bus.
