That means no ground loops, no noise pickup from VFD runs, and no common-mode voltage problems on long bus segments — if you've been chasing intermittent BF faults on a copper segment, the FO version is the fix. Rated transmission rate up to 12 Mbit/s with automatic baud detection across all standard PROFIBUS speeds. Data volume is 244 bytes each for inputs and outputs, enough for a full ET 200S station with up to 63 modules. Diagnostics are comprehensive: bus fault (BF) and group error (SF) LEDs plus a full diagnostics function and alarm capability. For an FO-based bus, the BF LED lights up if the FO link is down — check the simplex connectors first. Power draw: 200 mA from 1L+, 700 mA from backplane bus. Power loss 3.3 W typical; mains/voltage failure stored energy time 20 ms. Isolation between the bus and electronics is tested at 57 V DC / 60 V AC — this is a functional isolation, not safe galvanic separation, so treat the FO connectors as referenced to the same circuit ground.","metaTitle":"Siemens 6ES7151-1AB05-0AB0 IM 151-1 FO, 12 Mbit/s","metaDescription":"Siemens 6ES7151-1AB05-0AB0 SIMATIC DP IM 151-1 FO for ET 200S.
