Module profile
SIPLUS variant of the S7-1200 analog input, this 6AG1231-5ND32-4XB0 gives you 4 current or voltage differential inputs in a 45 mm wide package. It handles 4 to 20 mA, 0 to 20 mA, ±10 V, ±5 V, ±2.5 V, ±1.25 V ranges, plus resistance measurement and wire-break detection. Diagnostics and alarms are built in. Runs on 24 VDC, draws 65 mA typical, and dissipates 1.8 W. Spec'd for -40 °C to 70 °C ambient, so it's the one to grab for a cold warehouse or a hot cabinet.
