Features:

  • Sercos interface with selectable 4 Mbps or 8 Mbps data rates for high-speed deterministic communication.
  • Supports up to 16 drives with cycle times as low as 0.5 ms for coordinated multi-axis motion.
  • Position, velocity, and torque control modes with 760 mA backplane current draw and 5.0 W power dissipation.
The 1756-M08SE/B controls up to 16 drives from a single module. At 8 Mbps, four drives run at 0.5 ms cycle times—fast enough for printing and packaging lines. This reduces hardware count compared to single-axis modules.

Choose your speed. At 4 Mbps, run two drives at 0.5 ms or eight drives at 2 ms. At 8 Mbps, run four drives at 0.5 ms or 16 drives at 2 ms. Match cycle time to application needs without over-provisioning.

Operates from 0 to 60°C, stores from -40 to 85°C. Conformal-coated versions handle moisture and corrosion. The 1756-M08SE/B meets IEC radiated RF immunity at 10V/m, keeping communication reliable in electrically noisy plants.

The 1756-M08SE/B Allen-Bradley Interface Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • High-speed packaging machinery: Utilizes extremely short cycle times for high-speed cigarette packaging, bottling, and sealing.
  • Precision material handling: Applied to automated warehousing systems, multi-axis robotic arms for coordinate conversion and precise positioning.
  • Semiconductor and electronic assembly: Transmits signals via fiber optics in environments requiring high cleanliness and electromagnetic interference (EMI) protection.
  • Machine tools and metal processing: Supports flying shears, rotary cutting, and precision CNC coordinate control.
  • High-bandwidth digital communication: Supports SERCOS data rates of 4 Mbps and 8 Mbps.
  • Extremely low cycle time: At 8 Mbps, the cycle time is only 0.5 ms when controlling 4 axes; the cycle time is 1 ms when controlling 8 axes at full load.
  • Versatile control modes: Supports closed-loop control modes for position, velocity, and torque, which can be switched in real time according to process requirements.
  • Efficient cabling: Utilizes fiber optic loop connections, reducing up to 18 cables per axis compared to traditional analog wiring, significantly lowering installation costs and maintenance complexity.
  • Multi-axis Synchronous Collaboration: In complex production lines, the 1756-M08SE/B integrates eight servo drives (such as Kinetix 6000 or Ultra3000 series) into a single fiber optic loop, ensuring complete synchronization of all axes.
  • Harsh Electromagnetic Environments: Utilizing fiber optic transmission, it completely eliminates positional deviations caused by electrical noise when operating near large motors or high-frequency heating equipment.
  • System Diagnosis and Maintenance: Through Studio 5000 software, engineers can remotely monitor the real-time current, speed, and fault codes of the servo drives, significantly reducing downtime for troubleshooting.
Description
The 1756-M08SE/B is a high-performance Sercos interface module for Allen-Bradley ControlLogix platforms, supporting up to 16 drives with selectable data rates of 4 Mbps or 8 Mbps. Cycle times range from 0.5 ms to 2 ms depending on drive count and data rate. 

This module operates in any ControlLogix chassis slot and draws 760 mA from the 5.1V backplane and 2.5 mA from 24V, with 5.0 W power dissipation. The 1756-M08SE/B uses plastic or glass fiber-optic cables for Sercos communication, with various jacket options including non-jacketed, PVC, and nylon. 

The 1756-M08SE/B operates from 0 to 60°C and stores from -40 to 85°C, meeting IEC 61000-4-3 radiated RF immunity standards at 10V/m. Conformal-coated versions (K suffix) are available for harsh environments. 

This module solves the pain point of high-density synchronized motion control. The 1756-M08SE/B’s Sercos interface provides deterministic communication for up to 16 drives, reducing hardware count compared to single-axis modules.
