Carlo Gavazzi Dupline Fieldbus Module G88102201

Carlo Gavazzi G88102201 – Dupline Compact 2-Channel Input Module

The Carlo Gavazzi G88102201 is a small-sized, 2-channel monostable transmitter specifically designed for the Dupline® Building Automation concept. As part of Carlo Gavazzi's renowned Dupline fieldbus ecosystem, this ultra-compact input module enables flexible and discreet installation in existing or traditional light switches, junction boxes, or directly behind switch/pushbutton inputs. With its flush-mounted (plaster) design and IP65 protection rating, the G88102201 is the ideal solution for building automation, industrial signal acquisition, and distributed control applications where space is at a premium.

Key Features

2-Channel Digital Input – The module features two independent contact inputs for pushbuttons, enabling reliable signal acquisition from switches, sensors, and other dry-contact devices.

Ultra-Compact Flush-Mount Design – With dimensions of just 28mm (W) x 14mm (H) x 10mm (D), the G88102201 is one of the smallest Dupline input modules available. Its compact housing allows installation in junction boxes, behind switch plates, or directly in sensor cavities, making it perfect for space-constrained applications.

Dupline Bus-Powered – The module is powered directly by the Dupline two-wire bus, eliminating the need for external power supplies and simplifying wiring. Typical current consumption is less than 640 µA when unactivated and approximately 740 µA when all inputs are activated (at 128 channels).

Built-in Pulse Prolongation – An integrated pulse prolongation function (minimum 272 msec) ensures that even short input pulses from momentary pushbuttons or mechanical contacts are reliably transmitted to the bus.

IP65 Protection Rating – The module boasts an IP65 degree of protection, making it suitable for installation in environments where dust and moisture resistance are required.

Wide Operating Temperature Range – The G88102201 operates reliably from -40°C to +70°C (-40°F to +158°F), ensuring stable performance in demanding industrial and building automation environments.

Address Coding via GAP1605 – Channel addresses can be easily programmed using the GAP1605 hand-held programming unit (with Adapt 1605), enabling rapid system configuration and expansion.

cULus Approved – The module carries cULus approval according to UL60950, ensuring compliance with North American safety standards.

RoHS Compliant & SVHC-Free – The G88102201 is RoHS compliant and contains no Substances of Very High Concern (SVHC).

Technical Specifications

Wiring Connections

Note: To avoid noise on the Dupline bus, the Dupline programming wire must not be connected to D- until after the module has been programmed.

Applications

The G88102201 is ideally suited for a wide range of building automation and industrial applications:

• Building Automation & Lighting Control – Installed behind switch plates or in junction boxes for intelligent lighting control, occupancy sensing, and energy management systems
• Industrial Logistics Systems – Mounted at limit switches on conveyor sorting lines for real-time package flow and mechanical position monitoring
• Security & Alarm Systems – Acquiring signals from door contacts, smoke detectors, and emergency pull-cords for cross-area real-time alerting
• Environmental Monitoring – Connecting distributed temperature/humidity transmitters or flow switches to simplify巡检 wiring in hydroelectric plants and large facilities
• HVAC Systems – Monitoring valve positions, damper status, and fan operation in heating, ventilation, and air conditioning systems
• Access Control – Integrating with door contacts and request-to-exit buttons for comprehensive access management

System Integration

The G88102201 integrates seamlessly into the complete Dupline fieldbus ecosystem. It works in conjunction with:

• Dupline Gateways (such as SD2DUG24) – For integration with higher-level fieldbus systems and PLCs
• Dupline Channel Generators (such as GS3390) – For bus signal generation and system synchronization
• Dupline Repeaters (such as SB2REP230) – For extending bus transmission distances
• GAP1605 Programming Unit – For address coding and system configuration

The Dupline system supports bus, star, and tree topologies without requiring complex termination resistors, and a single master can connect up to 250 slave devices. The two-wire non-polarized communication significantly reduces installation errors and enables long-distance transmission on non-shielded cables.
