That means a 24 V nominal sensor with a 10% droop still registers as a clean \"1\" — no false-off from voltage drop on a long cable run. The module accepts 2-wire, 3-wire, and 4-wire sensors. For 3-wire sensors you need the BU type A0 BaseUnit with AUX terminals or a potential distributor module; 4-wire sensors require the BaseUnit plus a potential distributor module. Plan the BaseUnit order alongside this module — the I/O module itself does not carry the terminal blocks. Input filtering is parameterizable with adjustable debounce times from 0.05 ms up to 20 ms for both rising and falling edges. The minimum 0.05 ms setting suits high-speed counting or fast sensor pulses; the 20 ms maximum filters out contact bounce from mechanical switches. The module does not support isochronous mode or oversampling. ## DIN-rail footprint and wiring constraints Maximum cable length is 1 000 m shielded or 600 m unshielded. For most in-panel wiring (under 30 m) unshielded cable is fine; run shielded if the cable leaves the panel or passes near VFD output cables. Power dissipation is 1.6 W typical when all 8 inputs are supplied via encoder supply at 24 V. ## Diagnostics and I&M data for commissioning and maintenance The module supports I&M data from I&M0 through I&M3, meaning you can write a plant-specific location identifier, installation date, and maintenance annotation into the module's non-volatile memory. This is read out via the engineering station — useful for asset tracking in a large line. A group error diagnostic alarm is available. If any input channel detects a wire break (not supported for this module) or a supply fault, the module sends a diagnostic interrupt to the controller. The diagnostic alarm is enabled by default and can be parameterized per module. Firmware version is V0.0, and firmware updates are not possible. The module ships with fixed firmware; no field upgrade path exists.","metaTitle":"6ES7131-6BF01-0AA0 Siemens ET 200SP DI Module, 8 Inputs 24 V","metaDescription":"6ES7131-6BF01-0AA0 Siemens ET 200SP digital input module, 8 inputs 24 V DC, 15 mm wide, active production.
