TrolMaster Hydro-X Expander Station 4 - 4RS-1

TrolMaster Hydro-X Expander Station 4 - 4RS-1 is a universal power expansion module for expanding the number of devices controlled by the Hydro-X in a clean, centralized layout.

Built for growers who want more controlled outlets without clutter, this expander station keeps your device power management organized while staying focused on reliability. It’s designed around a trigger cable signal that mirrors the on/off call from a control module, so multiple devices can follow the same switching action without turning your control area into a patchwork of separate timers and plugs.

To support smoother startups, the 4RS-1 includes a time delay for reducing start-up surges. That staged startup behavior minimizes high start-up surges and supports inrush current reduction, which can help keep demanding equipment from hitting all at once. The result is steadier device start behavior and less stress on the power side of a busy room.

Inside, the design uses an individual power relay approach for each outlet, helping keep switching consistent and dependable across the station. Three wire terminals are built into the unit for a straightforward, tidy power feed, supporting a cleaner, more professional control install without unnecessary complexity.

This power expansion module is a strong fit for growers scaling a Hydro-X room who want orderly expansion, clearer power organization, and a more stable startup behavior for multiple devices. When your environment control build grows, the 4RS-1 helps keep device control structured, predictable, and easy to manage.
