Product Description P/N: 1771-A1B
Description
The Allen-Bradley 1771-A1B is a PLC-5 I/O chassis designed to house up to four I/O or communication modules along with a processor or adapter module in the leftmost slot. It supports a maximum backplane current of 16 A at 5.25 VDC and is intended for backpanel mounting in industrial control enclosures. The 1771-A1B provides the mechanical structure and backplane communication pathway essential for PLC-5 system operation.

Information About 1771-A1B
The 1771-A1B chassis is part of the Allen-Bradley PLC-5 platform and serves as the structural and electrical backbone for local I/O or controller configurations. Its four-slot design includes a dedicated left slot for a processor or I/O adapter, while the remaining slots accommodate communication interfaces or discrete/analog modules. The chassis distributes backplane power and coordinates data exchange among all installed modules, ensuring synchronized PLC-5 system operation. Designed for panel mounting, it features an open-style enclosure, grounding studs for proper EMC installation, and jumper settings for selecting internal or external power sources. Compatible power supplies include the 1771-P1, P2, P7, and PS7, making the chassis suitable for a wide range of PLC-5 configurations.
Key Features:
- Four-Slot PLC-5 Chassis: Provides space for a processor/adapter plus three additional modules.
- 16 A Backplane Capacity: Supports multiple high-load I/O or communication modules.
- Dedicated Controller Slot: Leftmost slot reserved for PLC-5 processor or adapter modules.
- Flexible Power Options: Jumper-configurable for internal or external power supplies.
- Panel-Mounted Design: Open-style frame suitable for industrial control cabinets.
- Rugged Construction: Rated for shock, vibration, and demanding industrial environments.
- Wide Power Supply Compatibility: Works with 1771-P1, -P2, -P7, and -PS7 supplies.
The 1771-A1B delivers the reliability and precision required for robust PLC-5 system expansion and modular control architectures.
