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. ## Production status Listed as current production. You can source this module against an RFQ with no lifecycle concerns. ## Installation notes Mounts on the S7-1200 rail. Requires the front connector (sold separately). Diagnostics are parameterizable. Cycle time all channels 625 µs.","metaTitle":"Siemens 6AG1231-5ND32-4XB0 SIPLUS S7-1200 4AI, -40-70°C","metaDescription":"SIPLUS ruggedized 4-channel analog input for S7-1200.
