FAQ

What is the primary function of a Dupline Channel Generator?

Its main role is to provide the necessary power and carrier signal for the 2-wire Dupline fieldbus, enabling communication between all connected modules. It also features a relay for system status monitoring.

This module requires a standard 11-pin circular relay socket, which can be mounted on a DIN rail or directly onto a panel.

While it operates on the fundamental Dupline protocol, it is not directly compatible with the advanced features of the modern 'smart-Dupline' (G3...) generation without a suitable gateway. It is designed for legacy systems.
