The module is parameterizable, with diagnostic alarms configurable per channel for wire-break or underrange, and a typical power draw of 1.5 W from the 24 VDC backplane. Keep it on the shelf as a critical spare if the line runs — the wide temperature range makes it a drop-in for many builds. Sits on the S7-1200 rail; width 45 mm leaves room for adjacent modules. Height 100 mm, depth 75 mm — check panel clearance if mounted near gland plates or door-mounted HMIs. CE, FM, and RCM approvals apply. Fall height max 0.3 m in package.","metaTitle":"Siemens 6ES7231-4HF30-0XB0 SM 1231, 8AI, -40..70°C","metaDescription":"Active Siemens S7-1200 analog input module. 8 differential inputs, 0-20 mA / ±10 V, -40 to 70 °C.
