製品紹介
The Allen-Bradley 1771-IAD AC/DC Input Module is a digital input module designed for the 1771 series PLC-5 automation systems from Allen-Bradley. This module provides reliable interface capability between field devices and the PLC processor, allowing the controller to monitor digital signals from industrial equipment such as sensors, switches, and other input devices.
The 1771-IAD supports both AC and DC input voltages, making it versatile for a wide range / industrial control applications. With 16 input channels, the module can handle multiple discrete input points, converting field signals into data that the PLC can process for monitoring, control, or automation logic.
Installed directly into a 1771 I/O chassis, the module receives power from the backplane and communicates with the PLC processor through the internal bus. Its robust design ensures reliable operation in factory environments, supporting voltage variations and maintaining signal integrity even under industrial electrical noise.
The 1771-IAD is widely used in automated manufacturing systems, process control facilities, and machine automation applications where reliable digital input monitoring is required.
