That temperature floor and ceiling are the main reason you'd reach for this variant over a standard S7-1200 analog module — the standard line tops out at 60 °C and bottoms at 0 °C. If your panel lives in a refrigerated warehouse, a freezer tunnel, or a desert cabinet, this is the part that stays within spec. Four differential inputs accept ±10 V, ±5 V, ±2.5 V, 0–20 mA, or 4–20 mA — no thermocouple or RTD onboard, so those transducer types need their own signal conditioners. The two outputs mirror the same ranges, handy for driving a recorder or a setpoint valve without an extra AO module. Diagnostics include wire-break and short-circuit detection on the inputs, plus a diagnostic alarm that can be parameterized. The module draws 60 mA from the 24 V DC backplane bus, dissipating 2 W typical — well within the S7-1200 CPU power budget. Maximum common-mode voltage is 12 V. Differential inputs reject ground loops up to that limit; above it you'll need isolation on the field wiring. IP20 enclosure means it's for a clean, dry cabinet — no washdown.","metaTitle":"Siemens 6AG1234-4HE32-4XB0 SIPLUS S7-1200 AI 4/AO 2, -40..70","metaDescription":"Current-production SIPLUS S7-1200 analog module, 4 inputs (current/voltage differential) and 2 outputs, rated -40 to 70°C.
