Key Features

• Integrated Safety Logic: Directly manages the E-Stop and safeguarding circuits. If a safety breach is detected, the board facilitates an immediate halt to ensure operator and equipment protection.

• Brake Control Management: Provides the necessary electrical signals to release or engage the mechanical brakes on each robot axis. This prevents the robot arm from collapsing under its own gravity when power is removed or an emergency occurs.

• High-Speed Signal Isolation: Equipped with industrial-grade relays and optocouplers to isolate delicate control logic from high-voltage power components, preventing electrical noise interference.

• Onboard Fault Diagnostics: Features status LED indicators that allow maintenance teams to verify safety loop continuity and identify hardware failures at a glance.

• 24/7 Industrial Reliability: Manufactured to original Swedish standards, this board is engineered for continuous operation in high-stakes manufacturing environments like automotive assembly and material handling.
