Information About Q38B

The Q38B Base Unit from Mitsubishi Electric serves as the primary backplane for the MELSEC-Q Series (QnU) PLC platform, offering a robust and scalable foundation for automation systems. With eight available slots, it supports a wide selection of control, communication, motion, and specialty modules, making it adaptable to diverse industrial automation needs. The ability to mount up to four CPUs—including standard logic CPUs, PC CPUs, and motion control CPUs—provides exceptional flexibility for both single-processor and multi-processor architectures. This design enables the Q38B to efficiently manage complex, high-speed control tasks while maintaining a compact installation footprint. Built to integrate advanced PLC, motion, and PC-based control on a single rack, the Q38B reduces system complexity and improves maintainability across modern automation environments.

Key Features:

  • Eight Expansion Slots: Supports a wide array of MELSEC-Q Series modules for scalable system design.
  • Multi-CPU Capability: Accommodates up to four CPUs on one base unit for high-performance parallel processing.
  • Broad Module Compatibility: Accepts logic, motion, PC-based, and specialty modules directly on the backplane.
  • Industrial-Grade Construction: Designed with a durable form factor to ensure long-term operation in industrial environments.
  • Certified For Global Use: Includes CE, UL, EAC, UKCA, and shipping approvals such as ABS, BV, DNV GL, LR, NK, and RINA.
  • Optimized For MELSEC-Q Systems: Provides fast communication between modules without the need for external networking links.
  • Compact And Lightweight Design: Measures 328 × 98 × 44.1 mm and weighs only 0.35 kg for space-efficient panel installation.
  • Reliable Automation Backbone: Acts as the structural and electrical foundation for advanced distributed control architectures.

The Q38B delivers the reliability and precision required for scalable PLC installations, multi-CPU configurations, and advanced automation architectures within the MELSEC-Q Series environment.
