Rated for 24 V DC, it draws a maximum of 180 mA from the supply voltage L+ and 50 mA from the load voltage L+ per load group, with a typical power loss of 4 W. ## Input characteristics and sensor compatibility The module accepts 2-wire sensors and defines signal \"1\" from 13 to 30 V with a typical current draw of 5 mA, while signal \"0\" ranges from -30 to +5 V — the permissible quiescent current for a 2-wire sensor is 1.5 mA maximum, which means the sensor's off-state leakage must stay below that threshold to avoid a false-on reading. Input filtering yields a transition time from \"0\" to \"1\" between 2 ms and 4.5 ms, and the module supports SYNC and FREEZE capabilities for coordinated acquisition across the ET 200L station. ## Diagnostics and isolation Diagnostics are available, with a bus fault BF (red) LED and a green status indicator per digital input, plus a green LED monitoring the 24 V supply voltage. Channel-to-channel isolation is not provided, but isolation between the channels and the PROFIBUS DP bus is tested at 500 V DC — the module also includes reverse polarity protection on the supply. ## Cable lengths and transmission rate Maximum cable length is 1,000 m shielded or 600 m unshielded, and the PROFIBUS DP interface runs at up to 1.5 Mbit/s. The usable terminal block is the TB 16L, and the module holds a mains/voltage failure stored energy time of 20 ms.","metaTitle":"Siemens 6ES7131-1BH12-0XB0 ET 200L 16 DI, 24 V DC","metaDescription":"Siemens 6ES7131-1BH12-0XB0 spare-part electronic block for ET 200L, 16 digital inputs at 24 V DC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC Communication Modules"],"specifications":{"title":"6ES7131-1BH12-0XB0","Alarms":"No","description":"*** SPARE PART*** SIMATIC DP, ELECTRONIC BLOCK FOR ET 200L, DIGITAL, 16 DI, 24V DC, EXPANDABLE WITH MAX. 16 CHANNELS WITH TERM.
