Equipped with 12 module slots and dual expansion interfaces, the hardware establishes high-speed power and data connections for local I\/O modules, power supplies, and communication units. The base plate supports distributed I\/O topologies across up to 6 substations via daisy-chain CAT7 cabling, providing deterministic real-time data transfers across the system bus.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eBS212\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eBachmann\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eAustria\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.0 kg (Typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard M1 12-Slot Backplane Dimensions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-30 to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003ePassive bus distribution (17 W nominal on BES212\/N variant)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Slots\u003c\/td\u003e\n\u003ctd\u003e12 Module Slots\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterfaces\u003c\/td\u003e\n\u003ctd\u003e2 x Bus Expansion Interfaces (RJ45, CAT7 cable up to 3 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Latency\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 1.5 us access time delay\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Expansion\u003c\/td\u003e\n\u003ctd\u003eUp to 6 substations (max 15 M200\/M1 modules per station)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eSnap-on EN 60715 DIN Rail or Panel Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication Velocity \u0026amp; I\/O Density Scaling\u003c\/h3\u003e\n\u003cp\u003eThe Bachmann BS212 optimizes backplane bus communication velocity across distributed racks by utilizing point-to-point hardware expansion links with minimal propagation delays under 1.5 us. High-density I\/O routing scales across multiple stations without needing protocol conversion gateways or specialized network software routines. The module backplane retains strict firmware flash compatibility across all connected digital, analog, and communication cards, ensuring synchronized memory access cycles during high-speed PLC scan executions.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What grounding requirements must be met when operating the BS212 with non-SELV voltage modules?\u003c\/p\u003e\n\u003cp\u003eA: The backplane chassis features a dedicated protective conductor tab. Installers must bond this tab directly to the cabinet earth bus using a short, high-strand copper strap to satisfy Class 1 protection requirements for non-SELV circuits.\u003c\/p\u003e\n\u003cp\u003eQ: How does the integrated power supply function on the BES212\/N hardware variant?\u003c\/p\u003e\n\u003cp\u003eA: The BES212\/N variant accepts an 18-34 VDC input (1.2 A at 24 VDC) and outputs regulated internal backplane voltages of +5 VDC (2 A), +15 VDC (250 mA), and -15 VDC (200 mA) to power remote I\/O slots.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eSnap the BS212 base plate securely onto an EN 60715 DIN rail or bolt it directly to the cabinet backpanel. Connect the protective earth conductor to the integrated grounding tab prior to installing active hardware cards. Mount active modules vertically into their assigned slots, ensuring multi-pin backplane connectors align fully before tightening the upper and lower retaining screws.\u003c\/p\u003e\n\u003cp\u003eFor multi-rack expansion, connect CAT7 cables with shielded RJ45 connectors between the dual expansion ports, limiting station-to-station runs to a maximum of 3 m. Keep communication lines separated from high-voltage AC power wiring inside wireways by at least 300 mm to prevent signal interference.\u003c\/p\u003e","brand":"BACHMANN","offers":[{"title":"Default Title","offer_id":52890657718584,"sku":"BS212","price":185.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/246.jpg?v=1788256736","url":"https:\/\/www.automodulexpert.com\/products\/automation-12-slot-backplane-base-board-bachmann-bs212-m1","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
