Allen-Bradley 1768-M04SE CompactLogix SERCOS Interface Module

Product Introduction

When multi-axis synchronized motion control demands precision and reliability, the Allen-Bradley 1768-M04SE delivers a robust SERCOS interface solution. Part of the CompactLogix family, this 4-axis SERCOS interface module integrates motion capability by allowing control of up to four Kinetix drives. It works with 1768-L43 and 1768-L45 CompactLogix controllers to form a cohesive motion system that reduces per-axis costs while maintaining high performance.

Technical Specifications Breakdown

The 1768-M04SE supports SERCOS Class B for position or velocity control modes. It offers two data rates: 4 Mbps and 8 Mbps. At 4 Mbps with up to two drives, the cycle time is 0.5 ms; with up to four drives, it extends to 1 ms. At 8 Mbps, all four drives achieve a 0.5 ms cycle time. The module draws 969 mA from the 5.2 VDC backplane and 0 mA from 24 VDC, with a power dissipation of 5.04 W. It consumes three connections and uses F-SMA standard screw-type fiber optic connectors. Fiber optic cables include plastic types (980 µm ± 60 µm core) and glass types (200 µm ± 4 µm core), with operating temperature ranges of -55…85 °C for plastic and -20…85 °C for glass.

Industry Applications

In packaging machinery, the 1768-M04SE enables precise synchronization of multiple servo axes for tasks like labeling, filling, and sealing. Its low cycle times (0.5 ms at 8 Mbps) ensure tight coordination between axes, reducing waste and improving throughput. In material handling systems, the module integrates with Kinetix 6000 drives to control conveyor sortation and robotic pick-and-place operations. The ability to support up to four drives from a single module simplifies system architecture and lowers total cost of ownership.

Installation & Setup Guidance

The 1768-M04SE mounts on a DIN rail or panel and occupies a single slot in the CompactLogix chassis. Use F-SMA screw-type connectors for fiber optic cables. For plastic cables, maintain a bend radius of 25 mm (0.98 in.) for non-jacketed and standard jacket types, or 40 mm (1.6 in.) for nylon jacket cables. Glass cables require a 30 mm (1.2 in.) bend radius. Ensure proper cable routing to avoid sharp bends that could degrade signal quality. The module is compatible with 1768-L43 (one module) and 1768-L45 (two modules) controllers.

Compatibility & Integration

This SERCOS interface module works with Allen-Bradley Kinetix 2000, Kinetix 6000, Kinetix 7000, and Ultra 3000 SERCOS servo drives. It supports electronic keying for secure module identification. The fiber optic network uses cables such as the 2090-SCEPxx-0 (non-jacketed), 2090-SCNPxx-0 (nylon jacket), and 2090-SCVPxx-0 (standard jacket) for plastic, and 2090-SCVGxx-0 for glass. Integration with CompactLogix controllers provides seamless motion programming via RSLogix 5000 software.

Selection Guide & Purchasing Advice

Before ordering the 1768-M04SE, verify your controller compatibility (1768-L43 or 1768-L45) and the number of axes required. Confirm the SERCOS data rate (4 Mbps or 8 Mbps) and cycle time needs for your application. Ensure you have the correct fiber optic cables and connectors.
