SST 5136-RE-VME Remote I/O VME Interface Card

The SST 5136-RE-VME is a VMEbus interface card that provides Allen-Bradley Remote I/O (RIO) connectivity for VME-based industrial control systems. This card enables VME systems to communicate directly with Allen-Bradley RIO networks, integrating VME processors with the widely deployed RIO fieldbus used in manufacturing automation.

Technical Specifications

The card implements the full Allen-Bradley Remote I/O protocol, supporting block transfers for intelligent devices. The physical interface provides galvanic isolation between the RIO network and the VMEbus, protecting the host system from electrical noise. The card is compatible with both 57.6 kbps and 115.2 kbps RIO network speeds.

• Bus Interface: VMEbus (A16/A24, D08/D16/D32)

• Network Protocol: Allen-Bradley Remote I/O (RIO)

• Supported Baud Rates: 57.6 kbps, 115.2 kbps

• Maximum Adapters (Scanner Mode): 32 RIO adapters

• Block Transfer Support: Full block transfer capability

• Isolation: Galvanic isolation between RIO and VMEbus

• Form Factor: 6U VME (single slot)

• Operating Temperature: 0°C to +55°C

Integration Features

The 5136-RE-VME includes a comprehensive API that simplifies integration with VME-based applications. The API handles all RIO protocol details, presenting the user with a simple read/write interface to I/O data and block transfer operations. This allows developers to focus on application functionality rather than network protocol implementation.

Application Environments

This interface card is ideal for VME-based systems that need to interface with Allen-Bradley PLCs and RIO I/O infrastructure. It is commonly used in manufacturing facilities where VME-based controllers or test systems must exchange data with PLC-controlled equipment, or in retrofit applications where VME processors replace existing PLCs while maintaining connectivity to RIO networks.
