Relay Output Expansion Module

Supports NORVI Controllers

The Relay Output Expansion module is designed to extend control capabilities for industrial and IoT systems. Featuring normally open (NO) relays rated for up to 5A at 30VDC or 250VAC, this module offers robust switching for high-load applications.

Powered by the MCP23008 port expander, it provides programmable relay control via I²C. The DIP switch configurable address allows easy integration of multiple modules, making it an ideal solution for developers and system integrators building scalable automation systems.

Key Features of the Relay Output Expansion

Normally Open (NO) relay outputs Handles up to 5A @ 30VDC / 250VAC (resistive) MCP23008 I²C Port Expander DIP switch address configuration
