It sinks 0.5 A per channel at 24 VDC, with a per-group maximum of 4 A and a module total of 8 A — the group limit governs real-world loading when several outputs fire simultaneously. MSO (isochronous mode) is supported, meaning the output update is synchronised to the PROFINET cycle — essential for applications that need deterministic switching, such as high-speed pick-and-place or cam-controlled motion. Short-circuit protection is built in, with a response threshold of 1 A typical per channel. The module also reports diagnostic alarms and channel status via green and red LEDs, so a faulted output is visible at the rack without a handheld tool. ## Switching performance and wiring constraints The output turns on in 100 µs max and off in 500 µs max — fast enough for most sequencing but not for PWM or high-frequency lamp loads (rated 10 Hz max on lamp load). Unshielded cable runs up to 600 m; shielded up to 1 000 m. The load resistance range for signal \"1\" is 48 Ω to 12 kΩ — stay inside that window or the module may not recognise the load as valid. All 16 outputs share a common reference — no channel-to-channel isolation. Firmware version V2.0.0 is factory-loaded. The module supports I&M data (I&M0 to I&M3) and prioritised startup, so it fits into a standard S7-1500 configuration without a firmware update for most projects. ## Panel fit and mechanical integration Width is 35 mm — one standard S7-1500 slot. Depth 129 mm, height 147 mm. The module snaps onto the DIN rail and connects to the backplane bus via the U-connector; no wiring to the backplane itself.","metaTitle":"Siemens 6ES7522-1BH00-0AB0 Digital Output Module, DQ16, MSO","metaDescription":"Siemens 6ES7522-1BH00-0AB0 S7-1500 digital output module, 16 transistor outputs, 24 VDC, 4 A per group, short-circuit protection, MSO support.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Digital Output Modules"],"specifications":{"MSO":"Yes","Depth":"129 mm","Width":"35 mm","title":"6ES7522-1BH00-0AB0","Height":"147 mm","RUN LED":"Yes; green LED","I&M data":"Yes; I&M0 to I&M3","ERROR LED":"Yes; red LED","Fuse blown":"No","Wire-break":"No","Lower Limit":"48 Ω","Upper Limit":"12 kΩ","description":"***Spare part*** SIMATIC S7-1500, Digital output module DQ16xDC 24V/0,5A; 16 channels in groups of 8; 4 A per group; diagnostics; Substitute value","For Uprating":"No","Short-circuit":"Yes","Shielded, Max.":"1 000 m","For Logic Links":"Yes","Weight, approx.":"230 g","lifecycle_stage":"current","\"0\" To \"1\", Max.":"100 µs","\"1\" To \"0\", Max.":"500 µs","Current-sourcing":"Yes","Diagnostic alarm":"Yes","Firmware version":"V2.0.0","Isochronous mode":"Yes","Power loss, typ.":"2 W","Rated value (DC)":"24 V","Unshielded, Max.":"600 m","On Lamp Load, Max.":"10 Hz","Prioritized startup":"Yes","Between The Channels":"No","Diagnostics function":"Yes","For Signal \"1\", Min.":"L+ (-0.8 V)","HW functional status":"E01","Isolation tested with":"707 V DC (type test)","Channel status display":"Yes; green LED","For Module Diagnostics":"Yes; red LED","Type of digital output":"Transistor","Current per group, max.":"4 A; see additional description in the manual","For Channel Diagnostics":"No","Current per module, max.":"8 A; see additional description in the manual","Response threshold, typ.":"1 A","Short-circuit protection":"Yes; Clocked electronically","Current consumption, max.":"30 mA","Current per channel, max.":"0.5 A; see additional description in the manual","Number of digital outputs":"16","With Inductive Load, Max.":"0.5 Hz; According to IEC 60947-5-1, DC-13","With Resistive Load, Max.":"100 Hz","Bus cycle time (TDP), min.":"250 µs","For Signal \"1\" Rated Value":"0.5 A","Controlling a digital input":"Yes","Reverse polarity protection":"Yes; through internal protection with 7 A per group","Monitoring the supply voltage":"Yes","Substitute values connectable":"Yes","Suitable for safety functions":"No","For Redundant Control Of A Load":"Yes","Digital outputs, parameterizable":"Yes","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","For Signal \"1\" Permissible Range, Max.":"0.5 A","PROFIBUS from GSD version/GSD revision":"V1.0 / V5.1","PROFINET from GSD version/GSD revision":"V2.3 / -","Power available from the backplane bus":"1.1 W","Execution and activation time (TCO), min.":"70 µs","Monitoring of the supply voltage (PWR-LED)":"Yes; green LED","Limitation of inductive shutdown voltage to":"L+ (-53 V)","STEP 7 configurable/integrated from version":"V5.5 SP3 / -","STEP 7 TIA Portal configurable/integrated from version":"V12 / V12"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$217.17 – $251.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/06be19e6ae0402e7764a1ac8fecad741.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=497512&mlfb=6ES7522-1BH00-0AB0"},"ai":{"faq":[{"question":"Does 6ES7522-1BH00-0AB0 have short-circuit protection?","answer":"Yes, short-circuit protection is built in, with a typical response threshold of 1 A per channel.
