Carlo Gavazzi G88104401 Dupline Universal Transmitter Input Module

The Carlo Gavazzi G88104401 Dupline transmitter input module provides four isolated inputs that feed the Dupline fieldbus, delivering compact flush-mounted I/O for building automation. Each input is color-coded (Input 1 Brown, Input 2 Red, Input 3 Orange, Input 4 Yellow) with a common return (Black) and the unit is powered by the Dupline bus itself. The 28 mm-square, black housing is made of Noryl GFN 1 and is designed for flush-mounted (plaster) installation, measuring 28 x 28 x 10 mm. Operating conditions include 0 to 50°C operating temperature, -20 to 70°C storage, and 20–80% non-condensing humidity. The device draws power from the Dupline network, with typical unactivated current around 1 mA and about 1.4 mA when all inputs are activated on a 128-channel Dupline system. Electrical characteristics per input specify a typical static current of about 50 µA, peak currents up to 20 mA, a voltage drop of ≤ 1 V, and a pulse prolongation of at least 272 ms. As a four-channel Dupline transmitter, it is designed to convert four input signals into the Dupline bundle for centralized monitoring, pairing with other Dupline devices in Carlo Gavazzi’s building automation product family.
