The BMXXBE1000H is an active-production backplane extender for the Modicon M340 platform, built for multi-rack configurations in severe environments. Confirmed ATEX directive 2014/34/EU compliance plus IEC 60079-0 for location G — passes the first checkpoint for Zone 1/Zone 2 installations. Also carries IEC 61131-2, IEC 61010-2-201, UL 61010-2-201, CSA C22.2 No 61010-2-201, IACS, and EN/IEC 61000-6-5 (interface types 1 and 2) as well as EN/IEC 61850-3. That coverage means it is certifiable for both process automation and substation automation panels without additional bridging paperwork.
Lifecycle stage is marked current — this is not an end-of-life or NRND part. No official successor exists; that is expected for an active, non-obsoleted accessory. Full compliance documentation (ATEX declaration, UL recognition, CE marking per 2014/35/EU and 2014/30/EU) is available with the shipment. The conformal coating and -25 to 70 °C operating range confirm the ruggedized designation — this will survive the thermal and condensation cycles of an offshore or desert panel.
Integration Notes
Two female SUB-D 9 connectors handle the rack extension. Current draw is 160 mA at 24 V DC and 22 mA at 3.3 V DC — budget that into the backplane power supply without surprise. Local diagnostics: one green RUN bus LED, one red collision COL rack LED, plus four green LEDs for rack address status. IP20 enclosure with conformal coating; mount inside a minimum IP54 cabinet if deployed in a wet or dusty Zone 2 location. Storage humidity tolerance 10–95 % without condensation. No potential equalization beyond the backplane frame ground is required, but verify the shield continuity on the SUB-D shells in multi-drop configurations.
