It provides 32 digital inputs at 24V DC, expandable by up to 16 additional channels using the TB 16SC terminal block of the SMART CONNECT system. Rated supply is 24V DC, with reverse polarity protection built in. The module draws a maximum of 180 mA from the supply voltage L+ and up to 50 mA per load group from the load voltage L+ (without load). It accepts 2-wire sensors, with a permissible quiescent current up to 1.5 mA. The input signal thresholds are -30 to +5 V for a logic 0 and 13 to 30 V for a logic 1, typical input current at signal 1 is 5 mA. ## Input timing and cabling limits Input delay from 0 to 1 ranges from 2 ms minimum to 4.5 ms maximum. This is the hardware debounce time; the downstream PLC scan must accommodate the worst-case delay for deterministic readback. Maximum cable length is 1 000 m shielded and 600 m unshielded. For PROFIBUS DP communication, the transmission rate is up to 1.5 Mbit/s. This part carries a current lifecycle stage. It is a designated spare part for the ET 200L system, which means it is not the primary production variant but remains available for installed-base support. Sourced to order against the BOM quantity.","metaTitle":"Siemens 6ES7131-1BL12-0XB0 ET 200L 32 DI, 24V DC, spare part","metaDescription":"Siemens 6ES7131-1BL12-0XB0 spare-part electronic block for ET 200L. 32 digital inputs, 24V DC, expandable to 48 channels.
