• Supply Voltage: 24 V DC (nominal), with permissible limits between 20.4 V DC and 26.4 V DC.
• Power Consumption: Approximately 2.5 W.
• Terminal Type: Screw terminals for secure electrical connections.
• Mounting: DIN rail mounting for convenient installation within control panels.
• Dimensions: Width of 22.5 mm, depth of 114 mm, and height of 99 mm.
• Standards Compliance: Meets EN60204-1, EN62061, EN954-1, and VDE0113-1 standards.
• Approvals: Certified by CCC, cUL, TÜV, and UL for global compatibility and safety assurance.
• Features:
• Positive-Guided Relay Outputs: Provides four safety contacts (N/O), ensuring reliable operation in safety-critical applications.
• LED Indicators: Equipped with LED displays to indicate the switch status of the safety contacts, facilitating easy monitoring and diagnostics.
• Feedback Loop Connection: Includes a connection for a feedback loop, enhancing the monitoring and verification of safety functions.
• Single-Channel Operation: Designed for single-channel wiring, simplifying configuration and reducing complexity.
• Safety Integrity: Maintains safety functions even in the event of component failure, ensuring continuous protection.
• Earth Fault Detection: Detects earth faults in the input circuit, causing the output relays to de-energize and the safety contacts to open, thereby preventing unsafe conditions.
