SAE-BCU-50

Robust Substation Automation

Engineered for Harsh Environments

The SAE-BCU-50 is a modular bay station controller designed to meet the toughest demands in substation automation. Built for use in high-voltage equipment, vibration-prone systems, and seismic-risk zones, it ensures long-term reliability, flexibility, and ease of use.

Its rugged rack-mounted design and compliance with IEC 61850-3 make it ideal for deployment in:

  • Power plants and medium-voltage stations (“G”)
  • High-voltage switchgear (“H”)
  • Signal and field connections (“f”)
  • High-voltage interfaces (“h”)

Key Features

  • Robust construction for extreme conditions
  • Modular architecture for easy customization
  • Flexible installation with multiple I/O and communication interfaces
  • Fast commissioning with intuitive configuration
  • High IT security in line with BDEW Whitepaper standards

Hardware Highlights

  • Powerful CPU (series5e, 1200 MIPS, 1 GB memory)
  • Modular expansion with a wide range of I/O and communication modules
  • Supports legacy SAE expansion cards
  • LAN integration for up to 6 separate network segments
  • High noise immunity and isolation class
  • Scalable: Cascade up to 16 racks as a single logical station
  • Up to 28 fiber-optic links to protection devices

Software & Configuration

Configuration is handled via setIT, SAE’s intuitive project software, allowing for fast commissioning and flexible system design. Advanced control tasks can be implemented via the integrated codeIT soft PLC, and OPC server integration is supported through connectIT.

Software Features

  • Syntax checks & error tracing with direct links to faults
  • Drag-and-drop copy functions & context-sensitive help
  • Real-time diagnostics and calculation logic
  • Built-in project documentation tools
  • Seamless implementation of IT security standards

The BCU-50 delivers outstanding performance, scalability, and resilience—ideal for critical infrastructure requiring long-term reliability and secure automation.
