6ES7288-2DR32-0AA0

A SIMATIC S7-200 SMART digital expansion module providing 16 digital inputs and 16 relay outputs. The inputs are designed for 24 V DC signals, while the relay outputs are rated for switching applications up to 2 A.

Core Specifications

Typical System Role

Used as a digital expansion point within S7-200 SMART control architectures for additional field-level I/O.

When Replacement Is Considered

Engineers may identify this part when digital inputs or relay outputs stop responding, field signals are lost, or an existing SM DR32 requires replacement.

Downtime Consideration

Loss of required digital I/O can interrupt machine sequences, actuator commands or field feedback, potentially preventing normal production operation until the affected I/O function is restored.

It is an SM DR32 digital I/O expansion module for the SIMATIC S7-200 SMART system, combining 16 digital inputs with 16 relay outputs.

The digital inputs are rated at 24 V DC. A signal below 5 V DC is recognized as “0”, while +15 to +30 V is recognized as “1”.

The SM DR32 provides 16 relay outputs. The specified switching capacity for resistive loads is up to 2 A.

Siemens specifies a typical current consumption of 165 mA for the 24 V DC input power.

The module is approximately 70 mm wide, 100 mm high and 81 mm deep.

The Siemens specification lists an IP20 degree of protection for the module.
