Product details

The 6AG1531-7NF10-7AB0: This is a current-production S7-1500 AI module, 8 analog inputs configurable for ±20 mA, ±10 V, 0-20 mA, 4-20 mA, 1-5 V, ±5 V, plus wire-break detection on 1-5 V and 4-20 mA ranges. Draws 53 mA from the backplane bus, dissipates 3.4 W. Horizontal mounting handles -40 to 70 °C; vertical derates to 40 °C max.

Sourcing & life cycle

Width 35 mm fits a standard S7-1500 slot; depth 129 mm clears most 200 mm cabinets. Backplane current of 53 mA leaves room in the power budget for additional modules. Jitter max 1 µs supports isochronous mode applications. Diagnostic alarms and limit value alarms (two upper, two lower per channel) reduce field-service time on fault calls.

Frequently asked questions

What is the listed depth and width?

Depth is 129 mm, width is 35 mm, height is 147 mm.

Will 6AG1531-7NF10-7AB0 drop into a panel specified around 6AG1123-2DB03-2AX0 without rewiring?

No. 6AG1123-2DB03-2AX0 is an S7-1200 CPU with a different form factor and backplane bus. This module is for S7-1500 racks only and requires the corresponding backplane connector and power supply.
