Product details

The Siemens 6ES7288-3AE08-0AA0 is an 8-channel analog input module for the S7-200 SMART family. It accepts 0-10V, 0-5V, ±5V, ±2.5V, or 0/4-20 mA signals and digitizes them to 12-bit resolution (11 bits plus sign). The module draws 61 mA typical from the 5 VDC backplane and consumes 2 W total. Supply must be 24 VDC within -15 / +20 % (20.4 to 28.8 V).

Key ratings in sourcing terms

No thermocouple or RTD functionality — this module handles voltage/current only. If you need direct temperature input, this isn't the part.

Frequently asked questions

What power supply does this module need?

24 VDC at 20.4 to 28.8 V (-15 / +20 %). It also draws up to 0.08 A from the S7-200 SMART 5 VDC backplane.
