製品紹介
The Allen-Bradley 1746-OA8 is an AC Digital Input Module designed for the SLC 500 programmable controller platform. It provides reliable control / AC-powered field devices in industrial automation systems where robust switching performance and electrical isolation are required.
This module /fers eight independent AC output channels, operating in a current sourcing configuration, making it suitable for driving loads such as contactors, solenoid valves, indicator lamps, and alarms. Each channel is designed to switch AC loads within a wide voltage range, allowing flexible integration into different industrial power environments.
Engineered for dependable operation in control cabinets, the 1746-OA8 emphasizes electrical robustness, predictable switching behavior, and seamless compatibility with SLC 500 processors. It is commonly used in legacy systems, retr/it projects, and standard machine control applications where AC outputs remain the preferred choice for field actuation.
