FAQ

Is this module compatible with the S5-115U PLC system?

No, the 6ES5430-6AA11 is specifically designed for the larger S5-130U, S5-130W, and S5-150U/S/K series PLCs. For the S5-115U, you would need a different series of I/O modules, such as the 6ES5430-4UA12.

What is the input delay time for this module?

The typical input delay for the 6ES5430-6AA11 is approximately 1.5 to 4.5 milliseconds, depending on the specific signal transition (from 0 to 1 or 1 to 0). This is important for applications requiring fast signal processing.

Does this module require an external power supply?

The module itself is powered via the S5 backplane bus. However, the 24V DC for the input signals must be supplied externally to the field devices and connected to the module’s input terminals.
