It accepts 120/230 V AC signals directly — no external signal conditioner needed — and communicates over PROFIBUS DP at up to 12 Mbit/s. The module reads a '0' signal from 0 to 40 V and a '1' signal from 79 to 264 V AC. The 40 V deadband between 40 V and 79 V prevents noise on long unshielded runs (up to 600 m) from causing false triggers. Input transition from 0-to-1 takes 0 to 25 ms — the 0 ms minimum means a fast PLC cycle can catch the leading edge, while the 25 ms maximum filters contact bounce on pushbuttons or relay outputs. ## Power draw and isolation — planning the backplane budget Typical current draw from the ET 200B backplane is 60 mA. Power loss runs 6 W at 230 V AC input and 4.5 W at 120 V AC — this is dissipated as heat inside the enclosure, so factor it into the panel thermal calculation when populating adjacent slots. Optocoupler isolation between the field inputs and the PROFIBUS DP logic is rated at 500 V DC to logic and 1500 V AC to the connecting terminals, meaning a short on the AC side won't propagate to the bus. ## Physical fit — the 235 mm wide block The submodule measures 235 mm wide by 130 mm high by 60 mm deep, including the electronic block and terminal base. It uses the TB6/AC terminal block with screw-type or spring-loaded connections for 3- and 4-wire sensors. The 16 inputs are grouped in fours with channel-to-channel isolation between groups — handy when mixing phases on adjacent inputs.","metaTitle":"Siemens 6ES7131-0HF00-0XB0 Digital Input Module","metaDescription":"Siemens 6ES7131-0HF00-0XB0 SIMATIC DP digital input module for ET 200B. 16 inputs, 120/230 V AC, PROFIBUS DP.
