It passes cyclic and acyclic data between the segments without acting as a master or slave itself — pure isolation and forwarding. Rated 0 °C to 60 °C, so it fits standard control cabinets with basic HVAC. Draws 90 mA at 24 V DC (20.4 to 28.8 V range) and dissipates 2 W typ. That power loss is low enough for a crowded backplane — no forced cooling needed at this heat load. Includes status indicators and diagnostics function, which helps during commissioning when a bus segment refuses to link. Physical footprint is 40 mm wide, 127 mm high, 117 mm deep, IP20. Fits a standard DIN-rail slot alongside other PROFIBUS components. The redundant infeed means it can accept power from either side — useful when the coupler sits between two panels with separate supplies. ## How it compares to a PROFIBUS DP slave Unlike the 6ES7155-5BA00-0AB0 DP slave, the 6ES7158-0AD01-0XA0 is not an I/O station — it has no inputs, outputs, or isochronous capability. The slave draws up to 1.2 A and dissipates 4 W typ, twice the coupler's 2 W. The coupler's 90 mA consumption is driven solely by its bridge logic and infeed circuits. If your panel needs to couple two DP lines (e.g., separating a safety CPU from a standard one), the coupler is the correct device. The slave would not perform that function; it can only attach to one bus. No cross-functional substitution exists between these two SIMATIC DP products.","metaTitle":"Siemens 6ES7158-0AD01-0XA0 DP/DP Coupler, PROFIBUS DP, 60°C","metaDescription":"Active Siemens DP/DP coupler for connecting two PROFIBUS DP networks.
