Description

Siemens SB 1231 AI 4x14-bit signal board adds four high‑resolution analog inputs to SIMATIC S7-1200 G2 CPUs without increasing the overall module width. Each channel can be configured for voltage ranges of ±10 V, ±5 V or ±2.5 V, or current ranges of 0–20 mA and 4–20 mA, with 14‑bit resolution. The compact 15 × 62 × 63 mm board plugs directly onto the front of the CPU, providing a space‑saving way to acquire precise process values from transmitters and sensors.
