Product details

The 6AG1231-5PF30-2XB0: This S7-1200 analog input module reads eight resistance thermometers across Pt100, Ni100, Cu10, and sixteen other RTD curves per the datasheet. The measurement principle is integrating, with a cold junction compensation accuracy of ±1,5 °C on the reference junction. Diagnostic alarms and wire-break detection are included. Ambient limits span -40 to 70 °C, so the module suits outdoor or unheated enclosures within that range.

Housing and power

The plastic housing measures 70 x 100 x 75 mm, matching the standard S7-1200 footprint. Supply is 24 V DC; typical power draw is 1.5 W. IP20 protection means the module is intended for enclosed control cabinets with no washdown exposure.

Frequently asked questions

What is the operating temperature range?

The module is rated for ambient operation from -40 °C to 70 °C.

Will 6AG1231-5PF30-2XB0 drop into a panel specified for 6AG1231-5PD32-4XB0 without rewiring?

Mechanically yes – both modules share the same 70 x 100 x 75 mm housing and backplane connector. The terminal assignments for common RTDs like Pt100 and Ni100 are identical. However, the hardware identifier in the PLC configuration must be updated to the PF30 model.

What compliance documentation does this brand provide?

The module is CE marked per the spec. No other compliance marks (RoHS, UL) are listed in the product data; Siemens can provide declarations upon request.
