Carlo Gavazzi GS38300143230: 16-Channel Digital Input Module for Dupline Fieldbus System

The Carlo Gavazzi GS38300143230 is a high-density, 16-channel digital input module designed for the innovative Dupline® fieldbus system. This module serves as a remote I/O node, enabling the efficient connection of up to 16 discrete digital signals (like switches, push-buttons, or proximity sensors) to a central control system over a simple, two-wire cable.

Engineered for reliability in demanding environments, this module is a perfect solution for industrial automation, building management systems (BMS), and extensive monitoring applications where reducing wiring complexity and cost is a priority.

Key Features and Benefits
High Channel Density: Integrates 16 discrete inputs into a single, compact module, maximizing space efficiency on the DIN rail and reducing the number of modules required for large-scale applications.

Universal 24V DC Digital Inputs: Each channel can be configured via a DIP switch to accept either a Wet Contact (sourcing 24V DC input) or a Dry Contact (volt-free contact, mechanical relay, or switch).

Long-Distance Communication: Leverages the Dupline fieldbus protocol to transmit data over remarkable distances—up to 10 km (6 miles)—on a single, unshielded twisted-pair cable.

Simplified Wiring and Cost Savings: The Dupline bus uses one pair of wires for both data communication and power delivery to all modules on the network, drastically cutting installation time, material costs, and complexity.

LED Status Indicators: Each channel features a bright LED to provide instant visual feedback on the input status (ON/OFF), facilitating quick troubleshooting and system diagnostics.

Rugged Industrial Design: Built to operate reliably in harsh conditions with a wide operating temperature range (-25°C to +70°C) and high immunity to electrical noise.
