Backplane for severe environments
The BMEXBP0400H: Four bus X slots with one Ethernet position. Current draw 49 mA at 3.3 V DC and 118 mA at 24 V DC. Power consumption 162 mW and 2.8 W respectively. MTBF 1588025 H.
Mounting and connection
Three fixing options: DIN-rail clip on 35 mm symmetrical rail, bolt-on with four M6 screws, or panel mount through four holes (4.32–6.35 mm diameter). The single expansion connector (XBE) handles daisy-chaining to additional racks. The IP20 enclosure is open-frame for panel interiors; no gland plate needed. Operational temperature spans -25 to 70 °C with 5–95% non-condensing humidity. The rack holds its full spec in that band without derating for high ambient or humidity.
