The Siemens 6ES7288-2DE08-0AA0 is a SIMATIC S7-200 SMART digital input expansion module with 8 digital inputs for 24 V DC applications and sink/source input configuration.
The 6ES7288-2DE08-0AA0 expands the digital input capacity of the SIMATIC S7-200 SMART platform. Its eight 24 V DC inputs are intended for discrete field signals that need to be acquired by the control system.
The module supports sink/source wiring and provides input-status indication, making it suitable for machine control signals, switches, sensors and other discrete 24 V DC field devices.
Typical search situations include loss of discrete input status, abnormal input indication or a failed expansion channel affecting machine sequence logic.
If required digital field states are no longer detected, interlocks, sequence steps or machine operating conditions may not be satisfied, potentially extending troubleshooting and equipment downtime.
For urgent replacement requirements, provide the exact part number and application details so our team can identify the appropriate supply option quickly.
