PRODUCT DESCRIPTION
Combined digital input and transistor output expansion
The Siemens 6ES7288-2DT32-0AA0 EM DT32 combines sixteen 24 V DC sink/source inputs and sixteen sourcing MOSFET outputs. Its transistor outputs operate from 20.4 to 28.8 V DC, distinguishing this S7-200 SMART expansion module from the relay-output EM DR32.
Input filtering is selected in groups of four from 0.2 to 12.8 ms. Outputs are rated up to 0.75 A per point across three isolation groups. No built-in overload protection is provided, so load limits, external protection and common-terminal wiring require review.

DIGITAL I/O EXPANSION
Combine discrete inputs and DC switching with the correct common groups
The DT32 adds separate input and output process connections through the S7-200 SMART expansion bus. Start with the host CPU capability and the available logic-power budget: Siemens lists 185 mA on the SM bus for this module, with additional field-side current associated with active inputs and connected output loads.
Its 24 V DC inputs can be arranged for sink/source wiring and use grouped input filters. The output circuits are sourcing MOSFETs, not potential-free relay contacts. Evaluate both the 0.75 A point rating and the 6 A common limit, and provide external protection because the output table specifies no overload protection.
The connector mapping deserves a separate check before commissioning. Output terminals span three isolation groups, and the common marked 4L+/4M is associated with terminals identified by the original table footnote. Keep that table with the wiring drawing, verify configured STOP values, and retain the manufacturer safety and inductive-load guidance.
Features:
- Separate input/output field circuits
- Grouped filtering and three output groups
- Point and common loading checks
The Siemens 6ES7288-2DT32-0AA0 requires the documented hardware configuration, installation conditions and interface arrangement to be verified before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Identify 6ES7288-2DT32-0AA0 on the installed module and compare it with the replacement record. The similarly sized DR32 is a different relay-output design. Preserve the original module order, orientation and address assignment, and retain the project configuration before disconnecting any wiring.
Compare the field circuits with the DT32 pin table rather than transplanting a relay-module connection pattern. Review supply polarity, the three output common groups, loading and any external protection. The preserved input-filter and STOP-output settings should be checked against the existing application requirements.
Siemens requires power removal from the CPU and related equipment before installing or removing the module. After secure mechanical and bus connection, complete the installation checks in the applicable project procedure. A matching channel count alone does not establish electrical equivalence or authorize an energized replacement.
Features:
- Exact DT32 identity
- Common-group and protection review
- Power-off replacement procedure
The Siemens 6ES7288-2DT32-0AA0 requires replacement verification based on its complete order number, installed hardware, signal configuration and project documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 6ES7288-2DT32-0AA0
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Is DT32 a relay-output module?
No. This exact DT32 article provides sourcing MOSFET outputs. The neighboring EM DR32 article uses relay dry contacts and must not be treated as the same electrical interface. -
How many input and output points does it add?
It provides 16 digital inputs and 16 digital outputs. Both sets belong to this expansion module; this is not a specification for the connected CPU onboard I/O. -
Can every output be loaded independently to its maximum?
Each output has a 0.75 A limit, but the 6 A common-group limit must also be respected. Use the exact DT32 connector allocation rather than assuming all terminals share one common. -
How are short input changes filtered?
The input filter offers seven settings between 0.2 and 12.8 ms, selected in groups of four inputs. Match filtering to the application rather than assuming each input has an independent filter. -
Does the module protect outputs against overload?
The technical table states that overload protection is not provided. The complete installation must include suitable circuit protection and follow Siemens wiring and inductive-load guidance. -
What should be checked when replacing a DT32?
Match the full article, its position and orientation, the wiring of the three output isolation groups, filter settings and STOP values. Remove power from the CPU and connected equipment before replacement. -
Do compact S7-200 SMART CPUs support it?
The manual explicitly excludes CR20s, CR30s, CR40s and CR60s from expansion-module support. Check the actual CPU and its power budget instead of assuming all SMART CPUs can use this module.
