PROFIBUS DP runs up to 12 Mbit/s on this module; the segment baud rate is set by the DP master, not by the station. ## Channel-side ratings Each digital output is rated 2 A on the '1' signal, with group-error indication via the red SF LED. Outputs are short-circuit protected but are NOT reverse-polarity protected — wire the field 24 V with the correct polarity. Switching speed is what governs the load mix: 100 Hz maximum on a resistive load, 1 Hz maximum on a lamp load, and 0.5 Hz maximum on an inductive load per IEC 60947-5-1, DC-13. Channel transition times are 3 ms typical in both directions, and the outputs are not isolated channel-to-channel. ## Power and thermal Station power is 24 V DC with 0.75 A rated value and a 0.75 A summation current up to 55 °C, so the upstream feeder and the power module both have to clear that budget across all eight outputs loaded together. Typical power loss is 5 W, which the IP65/67 housing has to dissipate without active airflow. Channel-level fault response is set at 4 A per channel, and per-socket current carrying is 4 A on each of sockets X1, X3, X5, X7 and 4 A on each of X2, X4, X6, X8 — the cable current-carrying capacity is the next bottleneck downstream of that. ## Mechanical and field environment The housing is 60 mm wide x 210 mm high x 28 mm deep, IP65/67 sealed, designed for cabinet-free mounting close to the sensors and actuators rather than back in the control panel. Unshielded cable runs are specified up to 30 m — beyond that, plan for shielded cable and verify EMC behavior in the field environment. Isolation is tested at 500 V DC, with 75 V DC / 60 V AC permitted between different circuits, which is the figure to check when the module sits adjacent to a higher-voltage field segment. ## Diagnostics and parameterization A red group-error SF LED is provided for module-level fault visibility; no channel-level alarms are reported back to the master from this variant. The module can also be used to control a digital input from the higher-level controller side, which is useful for handshake simulation during commissioning.","metaTitle":"Siemens 6ES7143-3BH00-0XA0 ET200S I/O, PROFIBUS DP, 8 DI/8 D","metaDescription":"Siemens 6ES7143-3BH00-0XA0 ET200S distributed I/O, PROFIBUS DP up to 12 Mbit/s, 8 digital inputs / 8 digital outputs, 24 V DC, IP65/67, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Digital Output Modules"],"specifications":{"Depth":"28 mm","Width":"60 mm","title":"6ES7143-3BH00-0XA0","Alarms":"No","Height":"210 mm","Lower Limit":"12 Ω","PROFIBUS DP":"Yes","Rated value":"0.75 A; up to 55°C max. 0.75 A (summation current)","Upper Limit":"4 kΩ","description":"SIMATIC DP, Basic module BM 143 ET 200ECO: 8 DI/8 DO, 2A; 8xM12, Duplicate assignment, Degree of protection IP65/67; Connection block 6ES7194-3AA00-0.A0 separately order","For Uprating":"No","2-Wire Sensor":"Yes","For Signal \"0\"":"-3 to +5V","For Signal \"1\"":"13 to 30V","Weight, approx.":"210 g","lifecycle_stage":"current","Power loss, typ.":"5 W","Rated value (DC)":"24 V","Unshielded, Max.":"30 m","Number of outputs":"8","On Lamp Load, Max.":"1 Hz","up to 55 °C, max.":"4 A; 4 A each for sockets X1, X3, X5, X7 and 4 A each for sockets X2, X4, X6, X8; note the current carrying capacity of the cable","At \"0\" To \"1\", Max.":"3 ms; Typical","At \"1\" To \"0\", Max.":"3 ms; Typical","Between The Channels":"No","For Signal \"1\", Min.":"2L+ (-0,8 V)","For Signal \"1\", Typ.":"7 mA","Group error SF (red)":"Yes","Isolation tested with":"500 V DC","Type of output voltage":"24 V DC","IP degree of protection":"IP65/67","Transmission rate, max.":"12 Mbit/s; 9,6 / 19,2 / 45,45 / 93,75 / 187,5 / 500 kbit/s; 1,5 / 3 / 6 / 12 Mbit/s","Number of digital inputs":"8","Response threshold, typ.":"4 A; Per channel","Short-circuit protection":"Yes","Number of digital outputs":"8","With Inductive Load, Max.":"0.5 Hz; According to IEC 60947-5-1, DC-13","With Resistive Load, Max.":"100 Hz","Between Different Circuits":"75 V DC/60 V AC","For Signal \"1\" Rated Value":"2 A","Controlling a digital input":"Yes","Reverse polarity protection":"No","from supply voltage 1L+, max.":"70 mA; Typical","Channel fault indicator F (red)":"No","Design of electrical connection":"4/5-pin M12 circular connectors","Diagnostic information readable":"Yes","For Redundant Control Of A Load":"Yes","For Signal \"0\" Residual Current, Max.":"0.5 mA","Status indicator digital input (green)":"Yes","Status indicator digital output (green)":"Yes","from load voltage 2L+ (without load), max.":"60 mA; Typical","Limitation of inductive shutdown voltage to":"2L+ (-44 V)","Permissible Quiescent Current (2-Wire Sensor), Max.":"1.5 mA","between PROFIBUS DP and all other circuit components":"Yes","for signal \"1\" permissible range for 0 to 55 °C, max.":"2.4 A","for signal \"1\" permissible range for 0 to 55 °C, min.":"5 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$444.50 – $847.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/eaa2d09cb181f4f534f179bc0da588d0.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=214510&mlfb=6ES7143-3BH00-0XA0"},"ai":{"faq":[{"question":"What is the listed depth of 6ES7143-3BH00-0XA0?","answer":"28 mm, as part of the 60 x 210 x 28 mm housing envelope that lets the module mount in tight field cabinets or on machine frames next to the I/O it serves."},{"question":"What is the listed width of 6ES7143-3BH00-0XA0?","answer":"60 mm.
