Product details

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.

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.
