Carlo Gavazzi Dupline Single-Channel Input Module G50101106 – Specifications and Technical Overview

The Carlo Gavazzi Dupline Single-Channel Input Module G50101106 provides a reliable and precise solution for acquiring signals from distributed sensors and switch devices within industrial automation networks. Since modern facilities increasingly demand efficient, noise-immune signal collection, this module allows engineers to integrate field devices seamlessly into Dupline® systems. Moreover, it delivers consistent performance, reduces wiring complexity, and supports real-time monitoring, which enhances control system reliability across manufacturing, utilities, and building automation applications.

Functional Overview

The G50101106 serves as a single digital input module, capturing one independent signal and transmitting it to the Dupline bus. Because industrial environments often feature numerous sensors, switches, and contact devices, using single-channel modules allows engineers to deploy the exact number of inputs required without unnecessary over-provisioning. Consequently, the module provides flexibility in network planning and simplifies channel management.

With the module installed close to field devices, signal degradation diminishes, and the network maintains high integrity. Furthermore, its clear diagnostic LEDs help technicians identify active channels and monitor power status in real time. Therefore, maintenance becomes faster, more efficient, and less prone to errors.

Electrical Specifications

The G50101106 operates on a 24 VDC nominal supply, compatible with standard industrial control power systems. Its internal circuitry stabilizes voltage variations and protects the device from electrical transients and interference commonly found near motors, relays, and other heavy machinery. This protection ensures that the input signal remains accurate and reliable throughout operational cycles.

Each input channel supports dry contacts, pushbuttons, and relay outputs, allowing integration with a wide range of field devices. The module also features filtering to prevent false triggers caused by contact bounce. Because the Dupline bus updates channel status continuously, operators receive real-time information without delay, enhancing process control accuracy.

Bus Communication and Integration

The G50101106 communicates seamlessly over the Dupline network. Its signals transmit with a predictable timing cycle, enabling central controllers such as PLCs, SCADA systems, or BMS platforms to access reliable data. Since Dupline manages addressing and channel organization, the module integrates without disrupting existing network configurations. Engineers can quickly map the input channel using standard configuration tools, which reduces installation time and ensures correct addressing.

Because of its efficient communication behavior, the module supports real-time monitoring of alarms, safety interlocks, or production signals. Consequently, automation systems remain responsive and reliable, even under high network load.

Mechanical Design and Housing

The module features a compact DIN-rail enclosure, which facilitates easy installation in control cabinets or distributed junction boxes. Its robust industrial-grade housing withstands vibration, dust, humidity, and electromagnetic interference. Cable terminals are clearly labeled, allowing technicians to wire devices quickly and safely. Moreover, the module’s compact design enables multiple units to be mounted side by side, which is particularly useful in retrofit projects where space is limited.

Environmental Performance

The G50101106 performs reliably across a wide temperature range, making it suitable for industrial sites, production floors, machine rooms, utility plants, and building management applications. Its design tolerates variations in humidity and electrical noise, ensuring consistent data acquisition even in challenging conditions. Engineers can trust the module to deliver stable and repeatable signals, minimizing downtime and maintenance requirements.

Typical Applications

Because the G50101106 captures precise single-channel input signals, it fits a wide variety of applications:

• Alarm and safety input monitoring

• Pushbutton and limit switch acquisition

• Machine interlocks and start/stop controls

• Building automation for lighting, HVAC, and access systems

• Conveyor system status detection

• Utility or water treatment sensor integration

In all these scenarios, the module enhances efficiency, simplifies wiring, and provides accurate real-time monitoring, which improves overall system reliability.
