140NOM25200 Schneider Electric DIO Head-End Adaptor Modicon Quantum

Schneider Electric 140NOM25200 DIO Head-End Adaptor | Modbus Plus Fiber Optic for Quantum

• Fiber optic communication: The 140NOM25200 features one Modbus Plus fiber optic port with TX/RX connectors. It also includes one Modbus RS232 port over twisted pair. The fiber port runs at 1 Mbit/s with 820 nm wavelength.
• Optical specifications: It supports multiple fiber types. Power loss budget reaches 11 dB for 62.5/125 µm, 16.5 dB for 100/140 µm, and 6.5 dB for 50/125 µm. Rise and fall time is 20 ns with 5 ns pulse width distortion.
• I/O capacity: It supports 30 input words and 32 output words. This allows efficient data exchange with remote I/O drops over fiber optic networks.
• Power and reliability: It consumes 4 watts of power. The bus current draw is 750 mA. It performs checksum, RAM, and processor verification for reliable operation.
• Built for demanding environments: It operates from 0 to 60 °C (32 to 140 °F). It holds marine certifications including DNV, GL, RINA, and RMRS. It also meets UL 508, CSA Class 1 Division 2, C-tick, and GOST standards. It withstands 10 V/m electromagnetic fields and 8 kV electrostatic discharge.
• Easy installation: The standard Quantum format fits any rack slot. IP20 protection suits cabinet mounting. It works up to 5000 meters altitude with 95% non-condensing humidity.
