Specification

The Allen-Bradley 1794-OA16 is a high-performance FLEX I/O AC output module engineered for demanding industrial environments. This 16-point discrete output module provides isolated switching for AC loads up to 240V AC, making it ideal for controlling motors, solenoids, relays, and other field devices in manufacturing and process automation. The 1794-OA16 utilizes rugged solid-state triac outputs with built-in surge suppression, ensuring long-term reliability in applications with frequent switching cycles. Each output channel is individually fused and optically isolated from the backplane, protecting the control system from transient voltages. Designed for the FLEX I/O platform, this module snaps onto a terminal base unit (e.g., 1794-TB3 or 1794-TB3S) for quick wiring and removal without disturbing field wiring. It supports both local and remote I/O configurations via ControlNet, DeviceNet, or EtherNet/IP adapters, offering flexibility for distributed control architectures. The 1794-OA16 is certified for global use with CE, UL, and CSA approvals, and operates reliably in temperatures from -20°C to +55°C.
