BESCHRIJVING

G34910040115 is a Dupline private line modem designed for long-distance point-to-point connections between two Dupline networks over owned or rented telephone cables exceeding 10 km. The modem converts Dupline signals into standard FSK (frequency shift keying) tone signals for transmission via telephone company standard lines and amplifiers. It features a rated operational voltage of 230 VAC ± 15%, operates at 45 to 65 Hz frequency, and has a typical power consumption of 3 W with maximum power dissipation of 4 W. The device includes a watchdog output with NPN transistor configuration (=35 VDC, =100 mA), LED indicators for supply (green), Dupline carrier (yellow), and communication fail (red), and is approved according to EU standard TBR 15 with CE marking. It is mounted on DIN-rail (EN 50022) and operates reliably in industrial environments with an operating temperature range of 0°C to +50°C and IP 20 protection rating. This modem is ideal for industrial automation and fieldbus applications requiring robust long-distance signal transmission without requiring code modules.
