It communicates over PROFIBUS DP at up to 1.5 Mbit/s, making it a direct-fit slice for existing ET 200S stations in process or factory lines. Rated IP20, it sits inside a cabinet, not on the machine face. Input filtering is fixed: signal transitions take 2–4.5 ms (both rising and falling), so this module suits applications where a few milliseconds of debounce are acceptable — think pushbuttons, limit switches, or proximity sensors on conveyor zones. For encoder counting or fast cam signals, you would want a higher-speed input slice. Power draw is modest — 2.2 W typical from the backplane, with a max 70 mA from the L+ supply. The module includes reverse-polarity protection and galvanic isolation between channels and the PROFIBUS DP bus, tested at 500 V DC. That isolation simplifies wiring in mixed-voltage panels. ## Mounting and environment notes Physical footprint: 145 mm wide, 60 mm high, 60.5 mm deep. It uses the ET 200S terminal block TB 16L, which is ordered separately. Operating temperature range is 0–60 °C horizontally mounted; derate to 40 °C for other orientations. Humidity tolerance is 5–95 % RH (class 2 per IEC 1131-2). Altitude range is 795–1080 hPa. ## Input characteristics and diagnostics Signal thresholds: logic '0' is –30 to +5 V, logic '1' is 13–30 V. Typical input current at '1' is 5 mA. The module supports 2-wire sensors (no external power needed for the sensor loop). It also offers FREEZE capability (snapshot inputs on a bus command) and diagnostic functions including a bus fault LED (red) and per-channel green status indicators. Maximum cable length: 1000 m shielded, 600 m unshielded. Power-failure hold-up time is 20 ms, enough to ride through brief dips without losing input state.","metaTitle":"Siemens 6ES7131-1BH01-0XB0 ET 200S 16DI PROFIBUS DP, 24 V DC","metaDescription":"Siemens 6ES7131-1BH01-0XB0 ET 200S digital input module, 16 inputs, 24 V DC, PROFIBUS DP, 2.2 W, IP20, active lifecycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Digital Input Modules"],"specifications":{"Depth":"60.5 mm","Width":"145 mm","title":"6ES7131-1BH01-0XB0","Alarms":"No","Height":"60 mm","description":"***Spare part*** SIMATIC DP, electronic module for ET 200L 16 DI, 24 V DC","2-Wire Sensor":"Yes","For Signal \"0\"":"-30 to +5 V","For Signal \"1\"":"13 to 30V","Shielded, Max.":"1 000 m","Operation, max.":"95 %; RH class 2 in accordance with IEC 1131-2","Operation, min.":"5 %","Weight, approx.":"130 g","lifecycle_stage":"current","Power loss, typ.":"2.2 W","Rated value (DC)":"24 V","Unshielded, Max.":"600 m","FREEZE capability":"Yes","Bus fault BF (red)":"Yes","At \"0\" To \"1\", Max.":"4.5 ms","At \"0\" To \"1\", Min.":"2 ms","At \"1\" To \"0\", Max.":"4.5 ms","At \"1\" To \"0\", Min.":"2 ms","Between The Channels":"No","Diagnostics function":"Yes","For Signal \"1\", Typ.":"5 mA","Isolation tested with":"500 V DC","Usable terminal block":"TB 16L","IP degree of protection":"IP20","Transmission rate, max.":"1.5 Mbit/s","Number of digital inputs":"16","Reverse polarity protection":"Yes","from supply voltage L+, max.":"70 mA; L4+ / L5+","Horizontal Installation, Max.":"60 °C; 40°C for other mountings","Horizontal Installation, Min.":"0 °C","Permissible Range, Lower Limit":"795 hPa","Permissible Range, Upper Limit":"1 080 hPa","Bus protocol/transmission protocol":"PROFIBUS DP","tested according to IEC 60068-2-27":"Yes; IEC 68, Part 2-27; half-sine, 15 g, 11 ms","between the channels and PROFIBUS DP":"Yes","Status indicator digital input (green)":"Yes","Mains/voltage failure stored energy time":"20 ms","Monitoring 24 V voltage supply ON (green)":"Yes","from load voltage L+ (without load), max.":"50 mA; Per load group (L1+ or L2+ / L3+)","Operation, tested according to IEC 60068-2-6":"Yes; IEC 68, Part 2-6; 10 to 57 Hz; (constant amplitude 0.075 mm); 57 to 150 Hz; (constant acceleration 1 g)","Direct data exchange (slave-to-slave communication)":"Yes; Transmitter (for digital outputs and hybrid modules ET 200L: not for L-SC or IM-SC)","For Signal \"0\", Max.
