The Delta AS16AP11R-A combines eight digital inputs and eight relay outputs, providing a practical interface between field devices and controlled equipment within an AS Series PLC system. The digital inputs can receive 24 VDC signals from common industrial devices such as proximity sensors, photoelectric sensors, push buttons and limit switches. The eight relay outputs provide electrical switching flexibility for compatible AC and DC loads.
One of the main advantages of the AS16AP11R-A is its relay output architecture. Unlike transistor-only output modules intended for specific DC switching arrangements, relay contacts can be used with both AC and DC loads within the specified ratings. Each output supports up to 2 A, while the common circuit is rated up to 8 A. The module also uses a spring-clamp terminal arrangement that helps simplify field wiring and maintenance in control cabinets.
The AS16AP11R-A is suitable for automated machinery, packaging equipment, material-handling systems, production equipment and general industrial control applications where both discrete inputs and relay switching are required. Its 8DI + 8 relay output configuration can help reduce the number of separate I/O modules needed in a PLC panel while maintaining a compact installation. For replacement or system-expansion projects, the AS16AP11R-A should be matched with the existing Delta AS Series controller, field wiring arrangement and connected-load requirements.
