It drops into a 35 mm slot on the S7-1500 DIN rail, measuring 147 mm tall and 129 mm deep — the standard ET 200MP / S7-1500 module envelope, so it lines up with adjacent digital and analog siblings without special panel prep. ## Measurement ranges and where the diagnostics fire Four voltage spans are supported: 1 V to 5 V, -1 V to +1 V, -5 V to +5 V, and -10 V to +10 V. Wire-break detection is enabled, but only on the 1 V to 5 V range — circuits working in ±1 V, ±5 V, or ±10 V do not raise a wire-break diagnostic, so an open transducer must be caught by the limit-alarm path instead. Resolution is selectable: low, medium, high, and none, which lets the integrator trade noise against conversion time per channel. Each channel reports overflow and underflow, and the module emits a diagnostic alarm plus two upper and two lower limit alarms per channel — enough to bracket a process window and catch out-of-range excursions without leaning on the CPU. ## Field wiring constraints Shielded cable runs top out at 200 m — the integrator plans the conduit path against that ceiling, not the headline sensor range. Front-panel status is RUN (green) and ERROR (red); there is no MAINT LED, so a planned-replacement workflow is signalled through the firmware, not the bezel. Identification and maintenance data I&M0 through I&M3 is stored on the module, which keeps the asset tag, plant designation, and install date queryable from the controller for plant-bookkeeping hooks. ## Power and service Typical power dissipation is 0.75 W, which leaves headroom on the S7-1500 backplane budget when several AI modules are stacked in one station. Firmware ships at V1.0.0 and is field-updatable, so feature additions or bug fixes can be pushed without a swap.","metaTitle":"Siemens 6ES7531-7LH00-0AB0 AI Module, 35 mm, 1–5 V","metaDescription":"Siemens 6ES7531-7LH00-0AB0 SIMATIC AI 4xU/I 16-bit module: lifecycle current, ±10 V / ±5 V / ±1 V / 1–5 V ranges, 35 mm slot, 200 m shielded.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog Input Modules"],"specifications":{"MSI":"Yes","Depth":"129 mm","Width":"35 mm","title":"6ES7531-7LH00-0AB0","Height":"147 mm","RUN LED":"Yes;
