FAQ

Question?
What is the function of the Over Current Protection (OCP) on the STB DDO 3705?

The OCP feature automatically shuts down an individual output channel if the current exceeds the 0.5A limit, protecting both the module and the connected device from damage due to short circuits or overloads.

Yes, but it requires an Advantys STB network interface module (NIM), such as the STBNIP2212 (Ethernet) or STBNDP2212 (Profibus DP), to connect the STB island to the PLC's communication bus.

A source output (also known as PNP) provides a positive voltage (24VDC) to the load. When the output is activated, current flows from the module, through the load, and to the common ground (0V).
