It carries 8 digital outputs (DQ) rated 24 V DC, 1.4 A max per output, with the total encoder supply current capped at 0.7 A per load voltage group — the two load groups isolate 8 outputs each, so a short on group 1 doesn't pull down group 2. The M8, 4-pin, shielded ET-Connection handles the field wiring; unshielded cable runs up to 30 m are allowed, but for the encoder signals keep it under 30 m to avoid noise coupling into the 32-bit counter. ## What the integrated counter and DI mean for the line This module packs 2 digital inputs (DI) and a 32-bit counter that counts up to 4 kHz on the encoder supply (48 Ω to 4 kΩ load range) — it's designed for a single-axis incremental encoder feedback directly on the remote I/O slice, saving a separate counter module. The DI thresholds are -3 to +5 V for signal \"0\" and +11 to +30 V for signal \"1\", with a typical 3 mA draw at signal \"1\" — it works with standard 24 V proximity sensors (2-wire supported) and the 0.05 ms min switching time catches fast edges from a bottle sensor or encoder pulse train. For lamp loads, the max switching frequency is 1 Hz — don't use this to strobe indicator lamps; the 20 ms max transition time (0-to-1 and 1-to-0) is fine for solenoid valves and contactor coils on a filling line.","metaTitle":"Siemens 6ES7143-5AH00-0BA0 ET 200AL Digital Output Module","metaDescription":"Siemens 6ES7143-5AH00-0BA0 ET 200AL digital output module, 8 outputs, 24 V DC, 1.4 A, with integrated counter and encoder supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Digital Output Modules"],"specifications":{"DI":"Yes","DQ":"Yes","Max.":"55 °C","Min.":"-30 °C","Depth":"40 mm","Width":"45 mm","title":"6ES7143-5AH00-0BA0","Height":"159 mm","Counter":"Yes","I&M data":"Yes; I&M0 to I&M3","Lower Limit":"48 Ω","Upper Limit":"4 kΩ","description":"SIMATIC ET 200AL, DIQ 16x24 V DC/0.5 A, 8xM12, Degree of protection IP67","In Groups Of":"8; 2 load groups for 8 outputs each","Number, max.":"4","2-Wire Sensor":"Yes","ET-Connection":"M8, 4-pin, shielded","Short-circuit":"Yes; Outputs to M; encoder supply to M; module by module","Counting width":"32 bit; Incl. sign","For Signal \"0\"":"-3 to +5V","For Signal \"1\"":"+11 to +30V","Parameterizable":"Yes","Weight, approx.":"195 g","lifecycle_stage":"current","Diagnostic alarm":"Yes; Parameterizable","Firmware version":"V1.2.x","Power loss, typ.":"4 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.":"16","At \"0\" To \"1\", Max.":"20 ms","At \"0\" To \"1\", Min.":"0.05 ms; 1.6 ms for channels 8 through 15","At \"1\" To \"0\", Max.":"20 ms","At \"1\" To \"0\", Min.":"0.05 ms; 1.6 ms for channels 8 through 15","For Signal \"1\", Min.":"L+ (-0.8 V)","For Signal \"1\", Typ.":"3 mA","HW functional status":"FS03","Output current, max.":"1.4 A; Total current of all encoders, max. 0.7 A per load voltage","Isolation tested with":"707 V DC (type test)","Channel status display":"Yes; green LED","For Module Diagnostics":"Yes; green/red LED","Current per group, max.":"4 A","IP degree of protection":"IP65/67","Counting frequency, max.":"2 kHz","Number of digital inputs":"16; Parameterizable as DIQ","Response threshold, typ.":"0.7 A","Short-circuit protection":"Yes; per channel, electronic","Between The Load Voltages":"Yes","Number of digital outputs":"16; Parameterizable as DIQ","With Inductive Load, Max.":"0.5 Hz","With Resistive Load, Max.":"100 Hz","Counting direction up/down":"Yes","For Signal \"1\" Rated Value":"0.5 A","For load voltage monitoring":"Yes; green LED","Freely usable digital input":"Yes","Reverse polarity protection":"Yes; Against destruction; encoder power supply outputs applied with reversed polarity, loads pick up","from load voltage 2L+, max.":"4 A; Maximum value","Freely usable digital output":"Yes","Substitute values connectable":"Yes; channel by channel, parameterizable","Current consumption (rated value)":"75 mA; without load","Between The Channels, In Groups Of":"8","permissible range, lower limit (DC)":"20.4 V","permissible range, upper limit (DC)":"28.8 V","For Signal \"0\" Residual Current, Max.":"0.5 mA","Between The Channels And Backplane Bus":"Yes","PROFIBUS from GSD version/GSD revision":"GSD as of Revision 5","PROFINET from GSD version/GSD revision":"GSDML V2.3.1","Switching tripped by comparison values":"Yes","from load voltage 1L+ (unswitched voltage)":"4 A; Maximum value","Limitation of inductive shutdown voltage to":"L+ (-53 V)","STEP 7 configurable/integrated from version":"V5.5 SP4 Hotfix 7 or higher","power supply according to NEC Class 2 required":"No","Design of electrical connection for supply voltage":"M8, 4-pole","Permissible Quiescent Current (2-Wire Sensor), Max.":"1.5 mA","STEP 7 TIA Portal configurable/integrated from version":"STEP 7 V14 or higher","Design of electrical connection for the inputs and outputs":"M12, 5-pole","Between The Channels And The Power Supply Of The Electronics":"No; 8 channels are non-isolated and 8 channels are isolated from supply voltage 1L+"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$125.73","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/599b454b0ca713179ffc9e6cd058c1dc.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=762829&mlfb=6ES7143-5AH00-0BA0"},"ai":{"faq":[{"question":"Can 6ES7143-5AH00-0BA0 be used with Siemens S7-1500 or S7-1200?","answer":"The module is part of the ET 200AL remote I/O family, which connects to any PROFINET controller — including S7-1500 and S7-1200 CPUs with a PROFINET port.
