The Siemens 6AG1531-7LH00-7AB0 is a SIMATIC analog input module with module-specific interrupt (MSI) enabled. It fits a single 35 mm wide slot and draws 0.75 W typical from the backplane bus. Inputs accept bipolar ranges from ±10 V down to ±1 V, plus unipolar 1 V to 5 V. Wire-break detection is active only on the 1...5 V range. Two upper and two lower limit values per channel can trigger alarms independently. Diagnostic alarm and overflow/underflow reporting are standard. Green RUN LED and red ERROR LED indicate module health; I&M data from I&M0 to I&M3 is supported for asset tracking.
