G34205502230 is an 8-channel Dupline transmitter designed to detect signals from external devices with voltage outputs ranging from 10 to 265 VAC/DC. The unit features 8 opto-isolated voltage inputs and operates on a 230 VAC ±15% power supply at 45 to 65 Hz frequency, with a typical power consumption of 4.5 VA. Key technical characteristics include an input voltage threshold of =1 VAC/DC for signal "0" and =10 VAC/DC for signal "1", operating times of =1 pulse train + 3 ms for signal "1" and =1 pulse train + 50 ms for signal "0", and a maximum cable length of 25 m. The transmitter is housed in an H4-housing suitable for DIN-rail mounting (EN 50022) and provides LED indications for supply status, input activation, and Dupline carrier presence. It is commonly used for monitoring the presence of mains supply to machinery and other industrial applications requiring reliable signal detection and transmission over Dupline fieldbus networks.
