BMXCRA31210
Schneider Electric
Overview
The BMXCRA31210 is an Ethernet Remote I/O drop adapter (CRA = Remote IO Adapter) in the the Schneider Electric automation portfolio range from Schneider Electric. It delivers stable control power at 24 V DC (via backplane) for the Schneider Electric automation portfolio racks.
Application & Technical Notes
As an ethernet remote i/o drop adapter (cra = remote io adapter), the BMXCRA31210 is intended for deployment in panel-based control cabinets and machine enclosures where the Schneider Electric automation portfolio equipment is installed. It conditions and distributes the low-voltage supply that powers the controller, I/O and communication modules on the same rack.
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. Ensure adequate ventilation and do not overload the supply beyond its published current budget; consider redundancy for critical racks. 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 BMXCRA31210, 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 output voltage and current to the the Schneider Electric automation portfolio load and allow headroom for future expansion. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
