Siemens 6ES7288-2QT16-0AA0 SIMATIC S7-200 SMART EM QT16 Transistor Output Module

Sixteen 24 V DC sourcing transistor outputs provide responsive switching for documented field loads in S7-200 SMART expansion systems.

Product Overview

Siemens 6ES7288-2QT16-0AA0 is the SIMATIC S7-200 SMART EM QT16 digital output expansion module. It adds sixteen sourcing transistor outputs for 24 V DC load circuits and does not add digital inputs. The module is suited to output expansion, maintenance replacement and control-panel projects that require semiconductor switching within the official electrical ratings. Before ordering, confirm the full article number, load voltage, steady-state and inrush current, output commons, external protection, suppression method, available expansion position and the controller project configuration.

Functions and Benefits

• Adds sixteen transistor outputs without introducing unused input channels.
• Sourcing semiconductor outputs support responsive 24 V DC switching.
• Channel status indication assists commissioning and fault isolation.
• Compact expansion width supports space-conscious control-panel layouts.
• Correct external protection and suppression help protect module and field circuits.

Applications

Installation, Wiring and Compatibility

Verify the output-common arrangement, 24 V DC load supply, polarity, per-channel current, group current and protective-device coordination before wiring. Apply suitable suppression to inductive loads and isolate power before installation or removal. Confirm the supported S7-200 SMART expansion position and update the controller project with the exact module configuration. Compare the original equipment label and terminal drawing before replacement.
