The NORVI X-R4 is a 4-channel relay output expansion module designed for the NORVI X modular controller platform. It provides electrically isolated relay outputs suitable for industrial control, automation, and power switching applications.

Relay outputs are controlled via an I²C I/O expander (PCA9538), allowing reliable expansion with minimal MCU I/O usage.
