Product Overview
The Allen-Bradley 1771-ASB is a remote I/O adapter module from the 1771 series. This module acts as a communication interface between a programmable controller and remote I/O chassis. It allows the controller to access I/O modules located at a distance. The 1771-ASB supports a single remote I/O link. It is designed for use with Allen-Bradley PLC-5 and SLC 500 families. This adapter module is a passive device that passes data to and from the controller. It does not perform logic processing. It is a key component for distributed control architectures. This module is a new original unit in stock.
Application Scenarios
The primary application is distributed I/O in industrial automation. It is used where I/O modules must be placed far from the main controller. Common scenarios include large manufacturing plants and material handling systems. It is also used in process control environments. The module is ideal for applications requiring I/O consolidation. It reduces wiring costs by placing I/O near sensors and actuators. It supports standard industrial warehouse storage conditions. The module is suitable for use in control cabinets with proper ventilation.

Installation & Maintenance Guide
Install the module into any slot of a 1771 I/O chassis. Ensure the chassis backplane provides adequate power. Connect the remote I/O link cable to the module's front connector. Set the module's address switches to match the controller configuration. Use twisted-pair cable for the remote I/O link. Maximum cable length depends on baud rate and cable type. Use standard industrial wiring practices. No routine maintenance is required beyond periodic cleaning. Keep the module free of dust and debris. Always follow safety procedures before handling.
Frequently Asked Questions (FAQ)
What is the primary function of 1771-ASB?
The primary function is to act as a remote I/O adapter. It interfaces a programmable controller with remote I/O chassis. It allows the controller to read inputs and write outputs at a distance.
Which controllers are compatible with the module?
The module is compatible with Allen-Bradley PLC-5 and SLC 500 families. It can also work with other processors that support the remote I/O protocol.
What is the maximum cable length for the remote I/O link?
The maximum cable length depends on the baud rate and cable type. For standard twisted-pair cable at 57.6 kbaud, the maximum length is 3048 meters.
Does this module require external power?
No, the module receives power from the chassis backplane. It requires 5V DC at a specific current draw. Check the chassis power supply capacity.
What is the typical operating environment for the module?
The module operates in temperatures from 0 to 60 degrees Celsius. It can be stored in temperatures from -40 to 85 degrees Celsius. Humidity range is 5 to 95% non-condensing.
