Specification

SEODescription

The GRT8-A2 AC220V Relay Module is a robust industrial control component designed for AC220V power systems, featuring 8 input channels and 8 relay output contacts (NO/NC) to directly drive loads up to 10A. This AC220V Relay Module supports modular expansion, allowing cascading with up to 16 additional modules via its integrated RS-485 communication interface (Modbus RTU protocol). Operating within a wide voltage range of AC 176-264V and a temperature range of -20°C to +60°C, the GRT8-A2 Relay excels in harsh environments. Ideal for factory automation, energy management, and building control systems, it offers high isolation (4kV) and LED status indication. While its AC220V-specific design ensures stable performance in grid-powered applications, it lacks compatibility with low-voltage DC systems. Compact DIN-rail mounting and screw terminal connections enhance installation efficiency.
