Backplane Power Supply Module Bachmann BS212

Product Description
The BS212 is a high-reliability backplane power supply for the Bachmann M1 automation system. It converts a 24 VDC input into stable internal voltages for CPUs, I/O modules, and high-speed communication cards, ensuring uninterrupted operation in industrial environments with fluctuating field power.

Built for rugged industrial use, the BS212 features galvanic isolation, over-/under-voltage protection, short-circuit safeguards, and thermal monitoring. Its fan-free Austrian design reliably operates from -30°C to +60°C, providing a slim 25 mm footprint for efficient cabinet integration.

Product FAQ
Q: Can the BS212 power external field devices?
A: No, it is designed solely for the M1 backplane. External devices require a separate supply like the CPC210.

Q: How can I monitor the power supply health?
A: Front LEDs show real-time status, and the Bachmann SolutionCenter allows programmatic monitoring of voltage and fault conditions.
