What's in the box — 16 relay outputs on PROFIBUS
The 6ES7132-1JH00-0XB0: Diagnostics are built in — the module flags bus faults via a red BF LED and reports channel-level faults. The SYNC capability means it can be used for time-critical output updates across the network.
Derating that matters — current vs. temperature
Output current per channel is 1 A up to 40 °C, but drops to 1 000 mA at 60 °C in horizontal mounting. If you're stacking modules in a warm cabinet, budget that derating into your load calculations. The module measures 191 mm wide, 85.5 mm deep, 61 mm tall — not tiny, so check your DIN rail real estate. The usable terminal block is a TB 16L AC, and the module plugs into the ET 200S rail. Max transmit rate of 6 Mbit/s means it fits fast segments, but keep unshielded cable runs under 600 m and shielded under 1 000 m.
