FAQ

Is this module compatible with any Advantys STB base?

Yes, the STB DDI 3725 is designed to work with standard Advantys STB I/O bases, such as the STB XBA series. Ensure your base has sufficient I/O capacity and the correct power distribution module (PDM) is used for the 24VDC supply.

What does ‘sinking’ input mean for wiring?

A ‘sinking’ input module provides the ground (0V) connection. To complete the circuit, your external sensors or switches must be connected to a positive (+) 24V DC supply. When the switch closes, it ‘sources’ the current to the module’s input terminal.

Can I use this module in a hazardous location?

The label indicates certifications for hazardous locations (FOR HAZ. LOC. CL I DIV 2 GP ABCD). However, you must adhere strictly to the installation requirements for such environments, including using an appropriate enclosure and following all local and national electrical codes. The warning “Do Not Disconnect While circuit is Live” is critical in these areas.
