Schneider BMECRA31210 Ethernet RIO Adapter

BMECRA31210 Modicon M580 X80 RIO Adapter

Product Introduction

The BMECRA31210 belongs to the Schneider Electric Modicon M580 platform. This module works as an Ethernet Remote I/O drop adapter, often called a CRA adapter. Therefore, it connects a remote X80 rack to the main controller over an Ethernet network. Furthermore, it carries two built-in RJ45 ports that run at 10/100 Mbps. These ports form an integrated switch, so engineers can daisy-chain several drops without extra hardware. In addition, the adapter speaks both Modbus TCP/IP and EtherNet/IP. As a result, it fits mixed automation environments where different protocols coexist.

Technical Specifications

Communication Features

The BMECRA31210 adapter provides two Ethernet RJ45 ports with 10/100 Mbps speed. These ports operate as an integrated switch, which simplifies network wiring. Meanwhile, the module supports EtherNet/IP and Modbus TCP/IP protocols. Consequently, it exchanges I/O data with M580 CPUs and other compatible masters. Besides, the adapter is not a CANopen master, so it serves Ethernet-based architectures only.

Electrical Data

Supply voltage for this adapter is 24 V DC, delivered through the backplane. Power consumption reaches 5.5 W during normal operation. Additionally, bus current draw is 500 mA at 24 V DC. Therefore, engineers should confirm that the rack power budget covers this load. The module occupies one slot on a BMEXBP Ethernet backplane.

Mechanical and Environmental Parameters

Dimensions of the BMECRA31210 are 100 × 28 × 93 mm (H×W×D). The unit weighs only 0.15 kg, so it adds little mechanical stress to the rack. Its protection rating is IP20, which suits clean control cabinets. Operating temperature ranges from 0°C to +60°C. Meanwhile, storage temperature spans -25°C to +70°C. Relative humidity must stay between 5% and 95%, without condensation.

Installation Guide

First, mount the BMEXBP Ethernet backplane inside the control cabinet. Next, insert the BMECRA31210 adapter into one free slot. Then, push the module gently until it locks onto the backplane connector. After that, connect the Ethernet cables to the two RJ45 ports. Specifically, use shielded cables for noisy industrial areas. Finally, verify the 24 V DC supply and check the front LEDs. If the LEDs show normal status, the drop is ready for configuration in the M580 project.
