GRENTON Relay Output Module (4 Outputs) INRUSH - DIN Rail Mounting, TF-Bus

The GRENTON Relay Output Module (4 Outputs) INRUSH is a high-performance DIN rail mounting device designed for professional building automation. Featuring four potential-free relay outputs with inrush current capability up to 80 A, this module is ideal for controlling resistive loads such as lighting, heating, and motorized devices. It communicates via the Grenton TF-Bus protocol and is powered directly from the bus, ensuring easy integration into existing Grenton systems.

Advantages

This relay module offers bistable (latching) relays that maintain their state even in case of power loss, enhancing reliability. The inrush current capability allows switching of loads with high starting currents without damage. LED indicators for each relay provide clear status feedback, and the compact 3-module DIN design saves space in the electrical cabinet.
