Product details

Siemens 6ES7231-4HA30-0XB0 is an S7-1200 analog input module that handles 0-20 mA and ±10V, ±5V, ±2.5V signals. Rated for -40 to 70 °C ambient, draws 0.4 W from the backplane. Approvals include cULus, CE, FM, KC, UL, CSA, Marine — covers most plant-floor compliance needs.

Temperature range and environment

The -40 °C minimum means it lives in cold storage areas or outdoor enclosures without a heater. The 70 °C maximum handles summer panel temps in a NEMA 4X box. No derating curve needed within that span for this module.
