Siemens 6ES7288-2DR32-0AA0 SIMATIC S7-200 SMART EM DR32 Digital I/O Module

Sixteen 24 V DC inputs and sixteen 2 A relay outputs combine field feedback and isolated load switching in one expansion module.

Product Overview

Siemens 6ES7288-2DR32-0AA0 is the SIMATIC S7-200 SMART EM DR32 mixed digital I/O expansion module. It combines sixteen 24 V DC sink/source inputs with sixteen relay outputs rated up to 2 A for documented loads. The relay architecture supports projects that require dry-contact switching or mixed load voltages, while the input side gathers machine-state feedback. It is suited to panel expansion, maintenance replacement and machine upgrades. Before ordering, confirm the complete article number, input commons, relay load voltage and inrush current, suppression method, terminal allocation, expansion position and the STEP 7 Micro/WIN SMART project configuration.

Functions and Benefits

• Combines sixteen field inputs and sixteen relay outputs in one expansion position.
• Dry relay contacts support documented AC or DC loads when ratings are observed.
• Status indication supports commissioning and maintenance checks.
• Relay output circuits require load-specific protection and suppression planning.
• A 70 mm housing provides the terminal density required for the 32-point configuration.

Applications

Installation, Wiring and Compatibility

Separate input commons from relay load circuits according to the official terminal plan. Confirm contact voltage, steady-state current and inrush current before assigning each relay output. Use suitable suppression on inductive loads and external protection because short-circuit protection is not integrated.

Revision notice: Confirm the complete suffix, terminal assignment, supply voltage, load category, available mounting space and original equipment label before ordering.

Procurement Checklist

1. Send the complete Siemens article number and required quantity.
2. Provide the controller or interface-module article number and expansion order.
3. State the destination country and requested shipping terms.
4. Provide load voltage, current and inrush information where outputs are involved.
5. Request available-unit and label photos if needed for approval.
