SAE-FW-50

FW-50 – Versatile and Powerful Remote Terminal Unit

The FW-50 is a modular and highly flexible remote terminal unit (RTU) from our series5e family. Designed to meet evolving demands in telecontrol, substation automation, and industrial communication, it offers high performance, robust design, and extensive configuration options.

Key Features

  • Modular design with three rack sizes (S, M, L)
  • Integrated router functionality with optional redundancy
  • Up to six isolated LAN segments for process and control center separation
  • Reuse of existing SAE modules (e.g., FW-10, FW-40)
  • Front-facing components (LEDs, switches, terminals) for easy access

Scalable Architecture

Need more capacity? The FW-50 supports cascading of up to 16 racks into one logical station—ideal for systems requiring thousands of I/Os. Installation is flexible with options for top-hat rail, wall, or 19” rack mounting.

Simple Configuration and Operation

Using our intuitive setIT software, the FW-50 supports:

  • Fast configuration and commissioning
  • Syntax and error checking
  • USB/SD card upload
  • PLC programming via codeIT
  • Visual status feedback via front-panel LEDs

Advanced IT Security

The FW-50 meets the latest BDEW and BSI IT security standards. Key features include:

  • Linux-based system
  • Customizable firewall rules
  • Role-based access control (RBAC)

Application Areas

  • Station and bay controller in medium/high-voltage substations
  • Monitoring and control in utilities, industry, and waste management
