It fits BU type A0 base units, which handle 1-wire through 4-wire connections depending on whether AUX terminals or a potential distributor module is used. ## Wire-break diagnostics and input filtering Wire-break diagnostics are configurable channel by channel, with an optional protective circuit using 25 kOhm to 45 kOhm resistors to suppress false diagnostics on simple encoder contacts. Input delay is parameterizable from 0.05 ms to 20 ms, and the module supports edge evaluation (rising, falling, or change) with a pulse extension down to 4 µs.","metaTitle":"Siemens 6ES7131-6BF00-2CA0 Digital Input Module, 24 V","metaDescription":"Siemens 6ES7131-6BF00-2CA0 digital input module for ET 200SP. 8 inputs at 24 V DC, wire-break diagnostics, 8 µs jitter.
