Product details

What's in the box

The Siemens 6ES7231-5PD32-0XB0 is an eight-channel RTD input module for the S7-1200 controller, supporting Pt100, Ni100, Cu10, and resistance measurement up to 600 ohms with wire-break detection and diagnostic alarm. Certified cULus, CE, FM, KC, UL, CSA, and Marine — one module that covers the approval sheet for machinery export or maritime use.

Panel fit

No parameterizable settings (fixed function), but diagnostic alarm and wire-break are enabled out of the box. No thermocouple or voltage/current inputs — this module is strictly RTD and resistance measurement across three ranges: 0–150 Ω, 0–300 Ω, 0–600 Ω.
