Upgrade Your Momentum Network with the 170INT11003 Interbus Adapter
Industrial networks often struggle when legacy communication modules cannot handle large device counts or long cable runs. The Schneider 170INT11003 communication adapter solves this by delivering reliable Interbus Generation SUPI III connectivity for Modicon Momentum systems. This adapter uses a Master/Slave access method with a continuous shift register to manage data flow across a ring network. Whether you are replacing a failed module or expanding an existing segment, this unit keeps your control architecture responsive and stable.

Key Technical Specifications That Drive Performance
The 170INT11003 supports 0 to 254 devices per segment, giving you exceptional scalability for distributed control. Its transmission rate of 500 kilobits per second ensures deterministic data exchange for time-sensitive operations. With a maximum cable distance exceeding 3,280 feet (1,000 meters) between devices and 1,312.14 feet (400 meters) between two modules, you can span large facilities without additional repeaters. The adapter uses two 9-pin D-Sub Interbus connectors and twisted pair cabling to reduce electromagnetic interference. Power dissipation stays low at 0.8 Watt without a fiber-optic adapter, supporting energy-efficient panel designs. The CRC-16 control parameter provides robust data verification across the ring topology.
Where the 170INT11003 Excels in Real-World Applications
Long-Distance Material Handling
Warehouse automation systems often require communication across hundreds of meters. This adapter’s 1,000-meter cable capability between devices lets you link conveyor controllers, sorters, and palletizers without signal degradation. The ring topology adds resilience because data can travel in the opposite direction if a cable breaks, reducing unplanned downtime.
High-Density Machine Cells
With support for up to 254 devices per segment, the 170INT11003 manages complex cells containing drives, I/O blocks, and sensors. The Master/Slave configuration ensures deterministic polling, which is critical for synchronized motion tasks. The 500 kbps rate handles the data volume without overwhelming the network.
Legacy Momentum Upgrades
When replacing an obsolete communication module, the 170INT11003 restores full Interbus Generation SUPI III functionality. Its IP20 protection class suits clean control cabinets, and the 0 to 60°C operating range matches typical factory environments. The adapter operates at altitudes below 16,404 feet (5,000 meters), making it suitable for high-elevation facilities.

Installation and Setup Guidelines
Mount the 170INT11003 inside a protective enclosure that maintains IP20 conditions. Use the two 9-pin D-Sub Interbus connectors to link the adapter into the ring network. Route twisted pair cables away from high-voltage wiring to preserve signal integrity. Verify that the ambient temperature remains between 0 and 60°C in non-condensing conditions. For storage, keep the unit between -40 and 85°C. No specific wiring diagrams or parameter values are provided here; always follow Schneider Electric’s official Momentum documentation for exact connection details.
Maintenance and Reliability for Long-Term ROI
Inspect the adapter periodically for loose connectors and cable wear. Because the unit has no moving parts, wear points are minimal. Keep the enclosure free of dust and moisture to maintain IP20 protection. The low 0.8 Watt power dissipation reduces heat buildup, extending component life. In a cost-benefit analysis, this reliability translates to fewer emergency replacements and lower total cost of ownership. If the product is discontinued or obsolete, contact SpareTechPLC for availability and replacement options. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
Compatibility and Integration
The 170INT11003 belongs to the Modicon Momentum series and communicates via Interbus Generation SUPI III. It integrates with Momentum controllers and I/O modules that support this protocol. The ring network topology requires compatible Interbus master and slave devices. Twisted pair cabling is mandatory for transmission. Ensure all devices on the segment use the same 500 kbps transmission rate. The CRC-16 control parameter must match across the network for proper data verification.
Selection Guide: What to Verify Before Buying
Confirm that your existing network uses Interbus Generation SUPI III. Check that your device count does not exceed 254 per segment. Verify that cable distances fall within the 1,000-meter and 400-meter limits. Ensure your power budget accommodates the 0.8 Watt dissipation. The 170INT11003 requires two 9-pin D-Sub connectors; inspect your current cabling for compatibility. SpareTechPLC supplies this adapter and can help you confirm fitment. Always request the latest datasheet before finalizing your order.
