BMECRA31210
Schneider Electric
Overview
The BMECRA31210 is an Ethernet Remote I/O Drop Adapter (NOT a CANopen master) in the Modicon M340 or M580 range from Schneider Electric. It extends Modicon M340 or M580 connectivity through its onboard communication interface.
Application & Technical Notes
As an ethernet remote i/o drop adapter (not a canopen master), the BMECRA31210 is intended for deployment in panel-based control cabinets and machine enclosures where Modicon M340 or M580 equipment is installed. It bridges the controller to higher-level networks, HMIs, SCADA and peer devices, carrying configuration, process data and diagnostics.
Key published characteristics include a 24 V DC (via backplane) rating, an operating temperature range of 0°C to +60°C. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Respect the published operating temperature window (0°C to +60°C); do not exceed it during commissioning or in enclosed panels without airflow. For storage and transit, keep the unit within -25°C to +70°C. Avoid condensation — the rated humidity is 5% to 95% (non-condensing); store and operate the module in a dry, pollution-degree-appropriate enclosure. Confirm network addressing, baud/rate and topology match the rest of the system; keep firmware consistent across the cell. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the BMECRA31210, distinguish three supply tiers: (1) genuine Schneider Electric stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Match the protocol, connector and topology to the rest of the Modicon M340 or M580 network and to the peer devices already installed. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
