Product details

Siemens 6ES7231-5PF30-0XB0 RTD/resistance input module reads Pt100, Ni100, and Cu10 sensors, plus direct resistance up to 600 Ω, with -40 to 70 °C operating range, 1.5 W, diagnostic alarms and wire-break detection.

The closest functional sibling is the SIPLUS variant 6AG1231-5PD32-4XB0, which uses the same signal chain and connector pinout. The standard 6ES7231-5PF30-0XB0 covers ambient temperatures from -40 to 70 °C and lacks the conformal coating of the SIPLUS line. If the panel needs extended temperature range (down to -40 °C is already matched), or resistance to condensation and corrosive gases, the SIPLUS part is the correct choice. For clean indoor cabinets, this standard module drops right in without rewiring.

Frequently asked questions

What is the closest functional second-source for this module?

The SIPLUS variant 6AG1231-5PD32-4XB0 is mechanically and electrically identical, but with wider environmental ratings and conformal coating. Use the 6AG1231 if the installation requires extended temperature or protection against condensation and aggressive gases. For standard indoor use, the 6ES7231-5PF30-0XB0 is the correct part.

What are the temperature limits for this RTD module?

The module is rated for an operating ambient temperature of -40 °C to 70 °C.

Will 6ES7231-5PF30-0XB0 drop into a panel originally wired for the SIPLUS 6AG1231-5PD32-4XB0?

Yes, it will. The two modules share the same dimensions, backplane connector, and terminal assignments. The only difference is environmental protection; electrical function is identical.

What compliance markings does this module carry?

The module has CE, FM, and RCM (formerly C-TICK) approvals.
