It draws up to 500 mA from the module bus at 24 V DC, with a typical power loss of 0.4 W. Input voltage threshold for signal \"1\" is +11 to +30 V DC; signal \"0\" is -30 to +5 V DC. Typical input current at signal \"1\" is 8 mA per channel. ## Input filter and interrupt timing for takt The input filter is parameterizable: 0.1 / 0.5 / 3 / 15 ms per channel. At the fastest setting (0.1 ms), the minimum on-to-off transition time is 0.05 ms, max 0.15 ms — deterministic enough to catch fast sensor edges on a body-shop weld line without missing a cycle. A parameterizable hardware interrupt is available, so the module can trigger an immediate PLC task on a signal edge instead of waiting for a cyclic poll. ## Physical fit in the ET 200S backplane Unshielded cable runs up to 600 m; shielded up to 1 000 m. The module provides electronic short-circuit protection of outputs to ground, module by module, with a diagnostic function that can be enabled or disabled per channel.","metaTitle":"Siemens 6ES7131-4BB01-0AB0 ET 200S 2DI, 24 V DC","metaDescription":"Siemens 6ES7131-4BB01-0AB0 ET 200S digital input module, 2 channels, 24 V DC, 500 mA rated supply, 15 mm wide.
