FAQ

What is the difference between a 'sourcing' and 'sinking' output module?

A sourcing output module, like this STB DDO 3705, provides (sources) a positive voltage (V+) to the load. The load is connected between the output terminal and the common ground (0V). A sinking module connects the load to ground (sinks current), and the load is powered by an external positive voltage source.

No, the STB DDO 3705 is a distributed I/O module and requires a network interface module (like an STB NIP for Ethernet/IP or STB NDP for Profibus-DP) and a base to function. It cannot operate as a standalone device.

OCP stands for Over Current Protection. This means each of the 16 outputs is protected against currents exceeding 0.5 Amperes. This feature helps prevent damage to the module and the connected device in case of a short circuit or overload.
