描述

GPD1901115 is a Dupline channel generator designed for 115 VAC power supply applications in industrial fieldbus systems. It generates pulse train sequences with a selectable number of channels (8, 16, 24, 32, 40, 48, 56, 64, 96, or 128) via rotary switch, and supports either 1 or 2 sequence modes to synchronize transmission signals across the entire Dupline network. The device features a quartz-controlled oscillator for precise timing, cable compensation for signal integrity, and operates at 115 VAC ± 10% with a rated impulse withstand voltage of 2.5 kV and power dissipation of 4 W. It includes LED indicators for supply status (green) and Dupline carrier presence (yellow), operates across -20°C to +50°C, and is housed in a plug-in D-housing format for DIN-rail mounting. This channel generator is essential for synchronizing non-powered Dupline transmitters and coordinating receiver status changes in complex industrial automation and control systems.
