Bachmann BS203 00009313-00 Controller Module

FAQ

Q: Is the BS203 the same as the S203?
A: No. The BS203 is an active backplane that interconnects modules electrically. The S203 is a passive DIN rail adapter with no electrical function, used only for mechanical mounting .

Q: What is the difference between the BS203 and a larger backplane like the BS216?
A: The primary difference is the number of module slots supported. The BS203 provides 3 slots, while larger backplanes like the BS216 accommodate more modules (up to 16) for larger system configurations .

Q: Can the BS203 be used for any M200/M1 module?
A: It is designed to host M1/M200 control system hardware (power supply, CPU, I/O). If your module requires backplane power or bus communication, you need a BS-series backplane rather than the S-series adapter .
