Description

The Allen-Bradley 8500-1746I is a specialized adapter interface module designed for the 8500 series. This module serves as a high-speed communication bridge, enabling Bulletin 1746 SLC I/O modules to be deployed in remote locations, physically separated from the main controller. Acting as a dedicated microcomputer, the module manages the exchange of control data between the SLC-500 PLC and distributed field devices, providing the flexibility required for complex industrial system architectures.

Features

  • Facilitates remote I/O communication for SLC-500 systems.
  • Utilizes the I/O RING protocol for high-speed, reliable data transmission.
  • Enables local processing of I/O signals to reduce latency in distributed applications.
  • Designed for integration with Bulletin 1746 I/O hardware.

Applications

This module is ideal for large-scale industrial environments where sensors, actuators, and other field devices are located at a significant distance from the main electrical cabinet. It is commonly used in distributed control systems where centralized processing is required but physical I/O distribution is necessary for cabling efficiency.

  • Verify that the module is securely seated in the chassis slot to ensure proper backplane connection.
  • Follow standard ESD (Electrostatic Discharge) handling procedures when touching internal components.
  • Ensure adequate ventilation in the cabinet to maintain operating temperatures below 60 degC.
  • Route communication cables away from high-voltage lines and sources of electromagnetic interference (EMI) to maintain signal integrity.

FAQ

What is the primary function of the 8500-1746I?

The 8500-1746I acts as a communication adapter that allows SLC-500 I/O modules to operate in remote locations, effectively extending the reach of the PLC system using the I/O RING protocol.

Can this module be used with standard SLC-500 processors?

Yes, it is designed to bridge communication between the SLC-500 PLC and distributed 1746 I/O modules.
