The module also supports limit-value alarms (two upper, two lower per channel) and overflow/underflow detection. Isolation is tested at 707 V DC between channels and backplane; good for industrial environments with mixed-voltage wiring. The RUN LED is green, ERROR is red, and there's a separate red LED for both module diagnostics and channel diagnostics. No MAINT LED, no oversampling, no isochronous mode—this is a straightforward integrating analog input.","metaTitle":"Siemens 6AG1531-7MH00-7AB0 Analog Input, 16 Ch, MSI","metaDescription":"Active-production 16-channel analog input module for current measurement (0/4-20 mA) with wire-break detection, MSI, and automation-sourced to order.","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":"6AG1531-7MH00-7AB0","Height":"147 mm","RUN LED":"Yes; green LED","I&M data":"Yes; I&M0 to I&M3","ERROR LED":"Yes; red LED","MAINT LED":"No","Step: low":"Yes","0 to 20 mA":"Yes","Step: High":"Yes","Step: None":"Yes","Wire-break":"Yes; Only for 4 ... 20 mA","Group error":"No","description":"SIPLUS S7-1500 AI 16xI BA based on 6ES7531-7MH00-0AB0 with conformal coating -40...+70 °C. analog input module, AI 16xI BA, 16-bit resolution accuracy 0.5%, 16 channels in groups of 16, common mode voltage 4 V DC, diagnostics, hardware interrupts; delivery including infeed element, shielding bracket and shield terminal: front connector (screw terminals or push-in) to be ordered separately","Oversampling":"No","Step: Medium":"Yes","4 mA to 20 mA":"Yes","Short-circuit":"No","Shielded, Max.":"800 m","Parameterizable":"Yes","Weight, approx.":"250 g","lifecycle_stage":"current","-20 mA to +20 mA":"Yes","Diagnostic alarm":"Yes","Isochronous mode":"No","Power loss, typ.":"1.2 W","Limit value alarm":"Yes; two upper and two lower limit values in each case","FW update possible":"Yes","Overflow/underflow":"Yes","Prioritized startup":"No","Between The Channels":"No","Diagnostics function":"Yes","Integration time (ms)":"2,5 / 16,67 / 20 / 100 ms","Isolation tested with":"707 V DC (type test)","Measurement principle":"integrating","Channel status display":"Yes; green LED","For Module Diagnostics":"Yes; red LED","For Channel Diagnostics":"Yes; red LED","For Voltage Measurement":"No","For current measurement":"16","Number of analog inputs":"16","Measuring range scalable":"No","Scalable measured values":"No","between the inputs (UCM)":"8 V DC","Common mode voltage, max.":"4 V","Calibration possible in RUN":"No","Vertical Installation, Max.":"40 °C; = Tmax","Vertical Installation, Min.":"-40 °C; = Tmin (incl. condensation/frost)","Adjustment of measuring range":"No","Horizontal Installation, Max.":"70 °C; = Tmax","Horizontal Installation, Min.":"-40 °C; = Tmin (incl. condensation/frost)","Input resistance (0 to 20 mA)":"25 Ω; Plus approx. 42 ohms for overvoltage protection by PTC","Monitoring the supply voltage":"No","Common mode interference, min.":"60 dB","Input resistance (4 mA to 20 mA)":"25 Ω; Plus approx. 42 ohms for overvoltage protection by PTC","Between the inputs and MANA (UCM)":"4 V DC","Integration time, parameterizable":"Yes","Between The Channels, In Groups Of":"16","Crosstalk between the inputs, max.":"-50 dB","Reparameterization possible in RUN":"Yes","Input resistance (-20 mA to +20 mA)":"25 Ω; Plus approx. 42 ohms for overvoltage protection by PTC","Between The Channels And Backplane Bus":"Yes","Power available from the backplane bus":"0.85 W","Current, relative to input range, (+/-)":"0.3 %","Monitoring of the supply voltage (PWR-LED)":"No","Installation altitude above sea level, max.":"5 000 m","For Current Measurement As 2-Wire Transducer":"Yes; with external supply","For Current Measurement As 4-Wire Transducer":"Yes","Protection against fouling acc. to EN 60664-3":"Yes; Type 1 protection","Linearity error (relative to input range), (+/-)":"0.1 %","Temperature error (relative to input range), (+/-)":"0.008 %/K","For Resistance Measurement With Two-Wire Connection":"No","Ambient air temperature-barometric pressure-altitude":"Tmin ...
