It is a source-input (PNP) module, accepting 2-wire sensors with a permissible quiescent current up to 1.5 mA. Signal thresholds are defined for a \"0\" signal from -5 to +30 V and for a \"1\" signal from -15 to -30 V, with a typical input current of 6 mA at 24 V. Response times from 0 to 1 and 1 to 0 are both between 2 ms and 4.5 ms. The module is not parameterizable and has no diagnostics function — it is a fixed-configuration input block, deterministic for the cycle. Reverse polarity protection is included on the supply, and isolation between channels and the backplane bus is tested at 500 V DC. Power loss is 1.2 W typical. The module supports unshielded cable runs up to 600 m and shielded runs up to 1,000 m, which covers most field wiring distances in a production cell. The module is a standard catalog item for the ET 200S platform, so lead times are typical for Siemens I/O components. ## Integration Note Status indicators are provided per channel (green LED). No group error SF LED is present — fault isolation is at the channel level only. The module occupies 3 bytes in the I/O map.","metaTitle":"Siemens 6ES7131-4BF50-0AA0 ET 200S 8 DI, 24 V DC, 15 mm","metaDescription":"Siemens 6ES7131-4BF50-0AA0 electronics module for ET 200S, 8 digital inputs 24 V DC, 15 mm width, 1.2 W power loss.
