2020年3月10日 · Rockwell Automation announces that as of March 10, 2020, the 1771 16 Point Digital Input Module will be discontinued and no longer available for sale. Customers are encouraged to remove references to the affected product (s).

Important: You can use an AC (120V) Output Module (cat. no. 1771-OAD) to directly drive terminals on an AC/DC (120V) Input Module (cat. no. 1771-IAD) (Figure 2).

The 1771–IAD module is a modular component of the 1771 I/O system requiring a properly installed system chassis. Refer to publication 1771–IN075 for detailed information on acceptable chassis, proper installation and grounding requirements.

digital ac I/O modules interface to ON/OFF devices such as limit switches, pushbuttons, motor starters, pilot lights, and annunciators. These modules are compatible with all current Allen-Bradley programmable controllers. This saves on spare parts, system engineering, inventory, and training costs. . The ac solid-state family of digital.

安装与维护方面 标准接线臂：配备1771-WH接线臂，这种标准化的设计方便了布线和连接，减少了布线错误的可能性，提高了安装效率，同时也便于后期的维护和检修.

This Allen-Bradley 1771-IAD 120V AC/DC Input Module is new from surplus stock and ships with standard documentation in manufacturer's original box. This unit also ships with a Allen-Bradley 1771-WH Wiring Arm.

The Allen-Bradley 1771-IAD is a PLC 5 Digital AC/DC Input Module. It contains information of various input devices such as pushbuttons, limit switches, pilot lights, motor starters, and annunciators to interface with on/off sensors and actuators.
