Descrição

Overview

The Allen-Bradley 1771-ASB is a PLC-5 series remote I/O adapter module designed to link distributed I/O chassis with programmable controllers across industrial networks. It enables high-reliability communication between remote racks and central PLC systems, supporting scalable automation architectures.

This module acts as a communication bridge for remote I/O configurations, allowing multiple input and output modules to be managed from a central control system over extended distances.

Key Features

  • Remote I/O communication interface for PLC-5 systems

  • Supports long-distance control network integration

  • Flexible addressing modes: 1-slot, 1/2-slot, and 2-slot configurations

  • Integrated field wiring arm for simplified installation

  • Configuration jumpers included for setup flexibility

  • Built-in diagnostic indicators for system monitoring

  • Supports up to 32 I/O points in mixed configurations

  • Designed for leftmost slot installation in I/O chassis

  • Suitable for distributed control and remote rack architectures
