What I/O configuration does the Siemens 6ES7323-1BH01-0AA0 provide?

The SM 323 module provides 8 digital inputs and 8 digital outputs, allowing discrete signal acquisition and actuator control within one S7-300 module.

What supply level and output rating apply to the 6ES7323-1BH01-0AA0?

The module uses 24 V DC digital I/O, with a rated output current of 0.5 A and a permitted output range of 5 mA to 0.6 A.

How quickly does the 6ES7323-1BH01-0AA0 respond to digital input changes?

Siemens specifies an input delay of 1.2 ms to 4.8 ms for both the 0-to-1 and 1-to-0 transitions.

Is the output stage of the Siemens 6ES7323-1BH01-0AA0 protected against short circuits?

Yes. The digital output stage uses electronic short-circuit protection, with a typical response threshold of approximately 1 A.

What should be checked when replacing a Siemens 6ES7323-1BH01-0AA0 in an existing S7-300 installation?

Confirm the exact order number, 8 DI / 8 DO configuration, 24 V DC operation, connector arrangement and the electrical requirements of the connected field devices before replacement.
