What this part is and where it lands
The Siemens 6AG1151-1AA05-7AB0 is a SIPLUS variant of the ET 200S IM 151-1 standard interface module, shipped as a spare part with conformal coating and an ambient temperature range from -25°C to 70°C. It replaces the standard 6ES7151-1AA05-0AB0 in environments that demand wider thermal tolerance and protection against moisture, dust, and aggressive atmospheres.
Key ratings and what they mean for fit
The module draws 3.3 W typical power loss from the backplane bus. It supports PROFIBUS DP only — no PROFINET IO stack and no TCP/IP onboard. Dimensions are 45 mm wide, 119.5 mm high, 75 mm deep, matching the standard ET 200S footprint for DIN-rail mounting.
