It reads Pt100, Pt200, Pt500, and Pt1000 sensors, plus resistance ranges 0–150 Ω, 0–300 Ω, and 0–600 Ω. The module includes wire-break detection and diagnostic alarms that can be read out over the backplane. Power draw is 0.5 W from the 24 V DC backplane supply. Width is 38 mm, depth 21 mm, height 62 mm — it occupies one slot on the S7-1200 rail. The module is plastic-housed and rated for a 0.3 m drop five times in its package. Maximum shielded cable length is 100 m using twisted-pair. ## Approvals & Compliance Carries cULus, CE, FM, KC, UL, CSA, Marine, and RCM (formerly C-TICK) approvals. No thermocouple or current measurement capability — this is a pure RTD/resistance input block.","metaTitle":"Siemens 6ES7231-5PA30-0XB0 RTD Module, -40 to 70 °C","metaDescription":"Siemens 6ES7231-5PA30-0XB0 RTD input module for S7-1200.
