Schneider Electric 140NOM25200 Modicon Quantum DIO Head-End Adapter
The Schneider Electric 140NOM25200 is a Distributed I/O (DIO) head-end adapter module engineered for the Modicon Quantum automation platform. It interfaces Quantum PLC controllers with distributed I/O drops over fiber-optic Modbus Plus networks at transmission rates up to 1 Mbps. Featuring two optical ports with ST connectors and one Modbus RS-232 serial port, the module provides high immunity to electromagnetic interference and supports optical communication distances up to 3 km point-to-point or 10 km in ring topologies.

Fiber-Optic Communication and Link Budget
The dual ST fiber-optic interfaces operate at an 820 nm optical wavelength to isolate communication signals from severe electrical noise and ground potential differences. Receiver sensitivity is rated at an average power of -30 dBm with a 20 dB dynamic range and a silence detection threshold of -36 dBm.
Verification: Confirm that total optical line losses across cable splices and connectors stay within the rated power budget for the selected fiber core diameter.
The optical budget accommodates diverse fiber types, providing 6.5 dB for 50/125 um, 11 dB for 62.5/125 um, and 16.5 dB for 100/140 um fiber. Depending on fiber quality and core sizing, the module supports point-to-point distances up to 3 km and ring architecture spans up to 10 km.
System Interface and Rack Powering
The 140NOM25200 mounts directly into standard Modicon Quantum backplane slots and requires no external power supply connection. Operating power is drawn entirely from the backplane bus, consuming 750 mA at 5 V DC with a typical thermal power dissipation of 4 W.
Verification: Ensure the Quantum backplane power supply module provides adequate 5 V DC capacity to meet the module's 750 mA draw alongside adjacent rack modules.
In addition to fiber-optic network routing, the module includes a front-facing RJ45 port supporting Modbus RS-232 serial communication. The unit handles an active I/O frame capacity of 30 input words and 32 output words per drop within IP20 control cabinet enclosures operating up to 5,000 m altitude.
Frequently Asked Questions
Q: What optical connector types are used on the 140NOM25200 module? A: The module is equipped with two ST-type fiber-optic connectors operating at an 820 nm wavelength.
Q: What is the maximum power budget supported for 62.5/125 um fiber optics? A: The module provides an optical power loss budget of 11 dB when paired with 62.5/125 um fiber-optic cabling.
Q: Does the 140NOM25200 require a dedicated external power supply wiring harness? A: No, it derives all operating power directly from the Modicon Quantum backplane bus (750 mA at 5 V DC).
