FAQ

Question?
Is this module compatible with a SIMATIC S7 system?

Answer

No, this is a SIMATIC S5 module and is not mechanically or electronically compatible with any SIMATIC S7 racks or processors.

Question?
What is the significance of the "E-Stand 02" on the label?

Answer

The "E-Stand" or "Ausgabestand" refers to the hardware revision of the module. Version 02 is a specific hardware release. When replacing a module, it is generally best to match the E-Stand, although later versions are often backward-compatible.

Question?
Does this module require an external power supply for the outputs?

Answer

Yes. While the module's logic is powered by the S5 backplane, the 24V DC load voltage for the 32 outputs must be supplied externally to the module's front connector terminals.
