8-Channel Multi-Function Relay Control Module This industrial-grade relay module features 8 independent input and output channels, each configurable with up to 20 preset functions for versatile control applications. It supports a wide DC input voltage range of 8V–36V, includes reverse-polarity protection to prevent damage from incorrect wiring, and features LED indicators for power status and relay activation. The module offers precise timing functionality with adjustable delays starting from 1 second, maintaining accuracy within ±1%. An automatic power-saving mode helps reduce energy consumption during idle operation. All user settings are retained after power loss. Input trigger modes (high-level or low-level pulse) are selectable via the COM terminal.
