Adds 16 digital inputs to a supported S7-200 SMART station.
01
Key Information
6ES7288-2DE16-0AA0 is the SIMATIC S7-200 SMART SM DI16 digital input module.
It provides 16 inputs for 24 V DC sink/source signals in four input groups and follows IEC 61131 Type 1 characteristics.
The module is powered from the S7-200 SMART backplane and provides one status LED for each input.
02
Functions
Accepts sink or source field wiring within the published 24 V DC input limits.
Separates the 16 points into four isolated input groups.
Provides per-channel LED indication for commissioning and diagnostics.

Installation
Assign the correct input-group commons before landing sink or source circuits.
Verify field supply polarity and the 20.4 to 28.8 V operating range.
Route standard and high-speed signal wiring according to the approved cabinet plan and cable-length limits.
Check every input LED, process value and diagnostic state after the hardware configuration is downloaded.

FAQ
What wiring detail most often prevents a 6ES7288-2DE16-0AA0 input from changing state?
An incorrect group common or source/sink reference can leave an otherwise healthy channel inactive.
Can all 16 points on 6ES7288-2DE16-0AA0 share one arbitrary common?
Use the documented four-group arrangement; do not bridge groups without the approved electrical design.
What should accompany a 6ES7288-2DE16-0AA0 enquiry?
Send the CPU model, slot, hardware configuration, input list, field voltage, source/sink arrangement and module label.
How should a channel on 6ES7288-2DE16-0AA0 be proved?
Measure the input voltage at the correct common, observe the channel LED and confirm the corresponding process image bit.
What differentiates 6ES7288-2DE16-0AA0 from the DI08 module?
This model has 16 points in four groups; the DI08 has eight points in two groups, so wiring and channel count differ.
