Schneider 170INT11003C Modicon Momentum Communication Adapter, 500 kbit/s

Product Overview

When building extensive industrial networks, the challenge of maintaining reliable communication across long distances and many devices is critical. The Schneider 170INT11003C communication adapter, part of the Modicon Momentum series, addresses this need with a robust ring topology and a transmission rate of 500 kbit/s. It supports up to 254 devices per segment and covers a maximum cable distance of 12,800 meters, providing flexibility for large-scale installations.

Technical Specifications Breakdown

The 170INT11003C operates in a ring topology, which enhances network redundancy and fault tolerance. Its transmission rate of 500 kbit/s ensures efficient data flow for control and monitoring tasks. The adapter accommodates 0 to 254 devices per segment, allowing scalable network expansion. A maximum cable distance of 12,800 meters between devices enables deployment across vast facilities. For local status indication, the adapter includes an LED indicator. It connects via two SUB-D 9 connectors, simplifying integration into existing systems. The device carries an IP20 protection class, making it suitable for indoor control cabinets. It resists electromagnetic fields up to 10 V/m and withstands electrostatic discharges of 4 kV and 8 kV, ensuring stable operation in electrically noisy environments. The fail-safe feature maintains operation under adverse conditions.

Industry Applications

In manufacturing plants, the 170INT11003C connects remote I/O stations and drives over long distances, enabling centralized control. For material handling systems, its ring topology provides network resilience, minimizing downtime. In process industries, the adapter supports distributed control architectures, ensuring reliable data transmission across extensive sites.

Installation & Setup Guidance

Mount the 170INT11003C in a clean, dry indoor enclosure with adequate ventilation. Use the two SUB-D 9 connectors to link the adapter into the ring network. Connect the first connector to the upstream device and the second to the downstream device to complete the ring. Verify cable lengths do not exceed 12,800 meters between any two devices. After power-up, check the LED indicator for proper status. Follow the Modicon Momentum user manual for detailed configuration steps.

Maintenance & Reliability

Periodically inspect the LED indicator and cable connections to ensure ongoing reliability. The adapter's IP20 protection requires installation in a dust-free environment. Its resistance to electromagnetic fields and electrostatic discharge reduces the risk of communication errors, contributing to long service life. Regular network performance checks help maintain optimal operation.

Compatibility & Integration

The 170INT11003C integrates seamlessly with other Modicon Momentum components, including I/O modules and controllers. It supports ring topology networks, making it compatible with systems that require redundant communication paths. Use standard SUB-D 9 cabling for straightforward connection.

Selection Guide & Purchasing Advice

Before ordering, verify that your network requires a ring topology and that the 500 kbit/s transmission rate meets your application needs. Confirm the cable distance and device count fall within the specified limits. For current availability and lifecycle status, contact BluePLC Industrial.

Troubleshooting & Common Issues

If the LED indicator does not light, check power supply connections. For communication errors, inspect cable integrity and ensure the ring topology is properly closed. Verify that the number of devices per segment does not exceed 254 and that cable distances are within 12,800 meters. Electromagnetic interference may cause intermittent faults; ensure proper grounding and shielding.
