It operates at 24 V DC rated value, with signal thresholds accepting +11 to +30 V for logic 1 and -30 to +5 V for logic 0 — standard 24 V sourcing (PNP) sensor compatibility. The 15 mm width packs high density into the backplane; depth is 58 mm, height 73 mm, and the module mates with BU type A0 base units. ## Parameterizable filtering and diagnostics Input delay is adjustable from 0.05 ms to 20 ms (min and max), tunable per module via the controller — useful for matching encoder pulse width or suppressing contact bounce. The module supports per-channel diagnostic alarm and group error, plus I&M data for identification up to I&M3. Wire-break detection can be enabled module-by-module using an optional external resistor (25 kΩ to 45 kΩ) wired to the sensor; this avoids nuisance diagnostics on simple mechanical contacts. Power dissipation is 1.7 W typical.","metaTitle":"Siemens 6ES7131-6BH01-2BA0 Digital Input Module, 15mm","metaDescription":"Active production digital input module for SIMATIC ET 200SP. 2-byte inputs, 24 V DC, 15 mm wide, parameterizable delays and diagnostics.
