Product Overview – Schneider 170INT11003 Communication Adapter
When designing or expanding an industrial network, the choice of communication adapter directly impacts system reliability and total cost of ownership. The Schneider 170INT11003 Communication Adapter delivers long-distance connectivity, low power consumption, and robust error checking – all within the compact Modicon Momentum form factor. This adapter enables a master/slave access method and continuous shift register operation, allowing seamless data exchange across up to 254 devices per segment.
By supporting the Interbus Generation SUPI III protocol, the 170INT11003 ensures deterministic data transmission over a ring network topology. With a maximum cable run exceeding 3,280 feet (1,000 meters) between modules, you can reduce the number of repeaters and associated wiring costs – a clear advantage for large-scale installations.

The 170INT11003 is designed for reliable operation in industrial environments. Its IP20 rating provides basic protection against solid objects, while the wide temperature range (-40 to 85°C storage) ensures durability during transport and storage. The CRC-16 error checking mechanism further enhances data integrity.
Real‑World Applications – Where the 170INT11003 Excels
-
Large‑scale material handling systems: With support for up to 254 devices per segment and cable runs beyond 3,280 feet, the 170INT11003 is ideal for conveyor networks spread across vast factory floors. The ring topology provides redundancy and simplifies wiring.
-
Process control in chemical plants: The adapter’s low power dissipation (0.8 W) reduces heat load in control cabinets, contributing to lower cooling costs and longer component life. The Interbus SUPI III protocol ensures deterministic communication for critical process parameters.
-
Automated warehousing: Twisted‑pair cabling and CRC-16 error detection minimize data corruption in electrically noisy environments, such as those with motor drives and high‑frequency lighting.
Installation & Setup Guide – Getting the 170INT11003 Ready
Mount the Schneider 170INT11003 on a standard DIN rail within the Modicon Momentum backplane system. Ensure the ambient temperature does not exceed 60°C and that the enclosure provides at least IP20 protection. Connect the two 9‑pin D‑Sub connectors to the Interbus ring using shielded twisted‑pair cables. Observe the maximum distance between two modules of 400 meters (1,312.14 ft) to maintain signal integrity. For longer distances, use fiber‑optic adapters (not included). Configure the master/slave address via the backplane interface – no external DIP switches are required on the adapter itself.
Keep the ring topology closed. If a break occurs, the CRC-16 error detection will flag the fault, allowing rapid diagnosis. The unit is self‑powered through the backplane; no additional power supply is needed.
Compatibility & Integration – Systems That Work with the 170INT11003
The 170INT11003 is a native component of the Schneider Electric Modicon Momentum series. It communicates natively with Momentum processors and I/O modules via the Interbus SUPI III protocol. Because Interbus uses a ring topology, the adapter can be integrated with other Interbus‑compliant devices from various manufacturers. The adapter does not support EtherNet/IP, Profibus, or Modbus TCP – it is strictly an Interbus Generation SUPI III device. For mixed‑protocol systems, a gateway (not included) may be required.
When ordering, verify that your controller supports Interbus SUPI III. The 170INT11003 is also compatible with legacy Modicon Momentum backplanes and power supplies.
Selection Guide & Purchasing Advice
Before purchasing the Schneider 170INT11003, confirm the following: (1) Your network requires the Interbus SUPI III protocol. (2) The total number of devices per segment does not exceed 254. (3) The planned cable distances stay within the 400 m limit between modules. (4) Your environment does not exceed 60°C operating temperature or 5,000 m altitude. (5) You have two 9‑pin D‑Sub connectors available on each device.
