The Carlo Gavazzi G34301149230 is a robust 8-channel relay output module designed for the innovative Dupline® fieldbus system. This module acts as a remote actuator interface, allowing a central controller to command high-power loads—like motors, lights, valves, and heaters—from distances of up to 10 km on a simple two-wire bus. It is an essential component for creating decentralized, cost-effective, and reliable control systems in industrial and building automation.
Key Features & Benefits
8 Form C Relay Outputs: Each channel features a versatile Form C (changeover) relay contact, allowing for flexible wiring configurations (SPDT-NO/NC). Each contact is rated for a robust 5A @ 250V AC.
Long-Distance Control: Leverages the proven Dupline fieldbus technology to transmit control signals over 10 km (6.2 miles) using a single, unshielded twisted-pair cable, eliminating the need for long, expensive individual load wiring.
Simplified Wiring & Cost Savings: The Dupline bus carries both communication and power for the entire network of modules, drastically reducing installation time, conduit size, and overall project cost.
LED Status Indicators: Each channel includes a clear LED to provide instant visual feedback on the relay's energized status, enabling quick diagnostics and troubleshooting on the factory floor or in the control room.
Rugged Industrial Design: Housed in a compact DIN rail-mount enclosure, it operates reliably in harsh environments with a wide temperature range (-25°C to +70°C) and high immunity to electrical noise.
