Four analog outputs, voltage or current, in a 45 mm slice
The 6AG1232-4HD32-4XB0 is a Siemens SIMATIC S7-1200 analog output module that gives you four individually configurable channels, each selectable for -10 V to +10 V or 0 to 20 mA output. Resolution hits 14 bits for voltage and 13 bits for current, which is enough for most process setpoint and speed reference signals without oversampling. It draws 45 mA from the 24 V DC field supply and 80 mA from the 5 V DC backplane bus, total typical power loss 1.5 W — a light load on the S7-1200 power budget. The module needs a front connector (ordered separately) and snaps into the standard DIN rail footprint at 45 mm wide.
Environmental tolerance: -40 to 70 °C with conformal coating
That temperature range, combined with conformal coating per IPC-CC-830A Class A and resistance to coolants, lubricants, diesel, and oil droplets, makes it a fit for cold storage, outdoor cabinets, and machine-tool environments where standard modules would fail. The module also carries Type 1 protection against fouling per EN 60664-3 and meets ANSI/ISA-71.04 GX group A/B for corrosive gas environments, plus salt-spray and oil resistance. Humidity tolerance is 95% at 25 °C without condensation.
Diagnostics and load drive capability
Built-in diagnostics cover wire-break detection on current outputs, short-circuit protection on voltage outputs, and supply voltage monitoring — all reportable as diagnostic alarms. Status of each output is readable back from the module. Load limits: 600 Ω max for current outputs, 1 kΩ min for voltage outputs. Common-mode voltage between output and AGND is limited to 12 V. Temperature error is ±0.3% of range at 25 °C, rising to ±0.6% at 55 °C.
Active production — sourced per RFQ
Lifecycle status is current production. This is not a legacy or phase-out part — it is the standard SIPLUS extreme variant still in the Siemens catalog.
