Schneider Electric BMXCRA31210 Modicon X80 Ethernet Remote IO Drop Adaptor

Configured for Ethernet remote input/output data collection and deterministic routing in Modicon M580 and M340 networks, the Schneider Electric BMXCRA31210 (BMXCRA31210 Ethernet Remote IO Drop Adaptor) provides direct physical/electrical execution. The module gathers input data from local X80 modules, publishes it to the remote I/O head adapter, and updates output modules via three RJ45 communication ports operating at 10/100 Mbit/s over IPv4 network topologies.

EtherNet/IP Deterministic Network Performance

This module executes real-time data transmission across EtherNet/IP deterministic networks utilizing a Rapid Spanning Tree Protocol (RSTP) ring topology. The internal hardware processes up to 1024 discrete channels and 256 analog channels with fixed 10 ms time-stamping intervals. Network routing and determinism are sustained through dual dedicated RIO ports alongside a single insulated service port configuration, preventing message collision and ensuring uniform backplane bus throughput to the connected PAC.

Frequently Asked Questions

Q: Does the module support Configuration Change On the Fly (CCOTF)?

A: Yes, the hardware architecture permits configuration modifications and module extensions during active runtime execution without interrupting the existing backplane bus state.

Q: What is the designated power source for this adaptor?

A: The module operates on an internal current draw of 1200 mA at a regulated input voltage of 3.3 VDC derived directly from the Modicon X80 rack backplane.

Field Installation Guidelines

  • Secure the module onto the Modicon X80 backplane slot using the integrated mechanical chassis screws to maintain structural stability and continuous grounding.
  • Utilize shielded twisted pair (STP) RJ45 cables for all Ethernet network connections to limit electromagnetic field interference.
  • Maintain unobstructed vertical clearances around the rack enclosure to facilitate natural thermal dissipation and ensure the surrounding air does not exceed 60 deg C.
