The unit meets Safety Integrity Level (SIL) 3 according to IEC 61508 and Performance Level (PL) e according to ISO 13849-1. The device is rated for use in Category 4 safety applications according to EN 954-1.

Safety Inputs: The unit provides 8 safety inputs that can be configured for various safety devices including emergency stops, safety gates, and light curtains. The inputs support two-channel monitoring with cross-circuit detection and offer adjustable response times from 10ms to 1000ms. All inputs feature short-circuit protection and optical isolation for enhanced safety.

Output Configuration: The relay features 3 safety-rated semiconductor outputs with a switching capacity of 0.5A at 24V DC. Additionally, it includes 2 safety relay outputs with a switching capacity of 6A at 250V AC. The outputs feature forced-guided contacts for reliable safety operation and monitoring.

Display and Interface: The integrated LCD display provides clear status information, diagnostic messages, and configuration settings. The display shows input status, output status, and any active faults or warnings. The unit features three navigation buttons for easy configuration and monitoring without additional tools.

Communication Capabilities: The safety relay supports AS-Interface Safety at Work (AS-i SAFE) communication for integration into automated safety networks. This allows for centralized monitoring and control of distributed safety devices throughout the manufacturing facility.

Electrical Characteristics: The typical power consumption is 2.5W during normal operation. The device features a maximum operating current of 100mA for the safety circuits. The electrical durability is rated for 100,000 operations at rated load for relay outputs and 1 million operations for semiconductor outputs.

Environmental Specifications: The operating temperature range is -25°C to +60°C. The storage temperature range is -40°C to +85°C. The relative humidity rating is 5% to 95% non-condensing. The device is rated for operation at altitudes up to 2000 meters above sea level. The vibration resistance meets IEC 60068-2-6 standards with 5-8.4Hz at 3.5mm amplitude and 8.4-150Hz at 1G acceleration.

Protection Features: The unit includes comprehensive protection against short circuits, overloads, and overvoltage conditions. All inputs and outputs feature optical isolation for enhanced safety and noise immunity. The device monitors its own internal safety functions and provides immediate shutdown in case of detected faults.

Certifications and Standards: The safety relay carries CE marking and complies with all relevant European directives. It is UL recognized and cULus listed for North American markets. The device meets IEC 60204-1 for electrical equipment of machines and complies with IEC 60947-5-1 for low-voltage switchgear and controlgear.

Configuration and Programming: The device can be easily configured using the front-panel buttons and display. No additional software or programming tools are required for basic configuration. The unit stores configuration settings in non-volatile memory, ensuring settings are maintained during power outages.

Diagnostic Capabilities: Advanced diagnostic functions include detailed fault messaging, event logging with time stamping, and status monitoring of all connected safety devices. The system provides clear visual and electrical feedback for all safety states and fault conditions.

Application Flexibility: The modular design allows for expansion with additional safety modules to accommodate larger safety systems. The unit supports connection of up to 31 AS-i safety devices through the integrated AS-interface connection.
