It reads Pt100 or Ni100 over a configurable 0-600 Ohm range, with 16-bit resolution feeding the AS-i network. The unit is rated IP67, takes an auxiliary supply of 24-30 V via M12, and draws up to 500 mA from the AS-i bus when powering sensors. Mounts on standard rail or wall via the K60 mounting plate. The 2-channel module uses 4-wire connection internally for better accuracy; the field wiring is M12 screw terminals. Three LEDs on the front panel: green for AS-Interface communication, green for auxiliary power, and a red FAULT LED tied to a Severity 3 alarm classification — this indicates a system-level condition rather than a module failure, so plan for diagnostic checking at the master.","metaTitle":"Siemens 6AG1207-3BQ40-7AA3 AS-i Analog Input Module, 2 Pt100","metaDescription":"Sourcing the 6AG1207-3BQ40-7AA3?
