FAQ
Q1: What is the Bachmann BES212/N used for?
It is a bus expansion slave module with an integrated power supply, used with the BEM211 master to extend the M1/M200 controller backplane to distributed I/O substations up to 3 meters away .
Q2: What is the difference between BES212 and BES212/N?
The BES212 (00012847-00) is the standard slave module without an integrated power supply. The BES212/N (00012848-00) includes an integrated 24 V power supply (18–34 VDC, 17 W nominal) for the substation .
Q3: How many substations can be connected?
Up to 6 distributed substations in a daisy-chain topology, each supporting up to 15 M200 standard modules .
Q4: What cable is used for the bus expansion?
CAT7 special cable with RJ45 connectors, with a maximum length of 3 meters between stations .
Q5: What are the power supply specifications?
Input range 18–34 VDC, max. 1.2 A at 24 V, nominal power 17 W. Outputs: +5 V (2 A), +15 V (250 mA), -15 V (200 mA), with reverse polarity protection .
Q6: What is the access time for the expanded I/O?
Less than 1.5 µs, ensuring the expanded I/O behaves as if it were local to the controller .
Q7: Does the BES212/N have an integrated watchdog?
Yes, the slave modules include an integrated watchdog for monitoring module operation .
Q8: What are the environmental ratings?
Operating temperature -30 °C to +60 °C, storage -40 °C to +85 °C. Certifications: CE, UKCA, cULus (older datasheets may also list CCC) .
