Information About 774540
The 774540 is part of the Pilz PNOZ X safety relay series developed for compact and flexible safety control in fixed industrial installations. It supports both single-channel and dual-channel input wiring, allowing adaptation to different safety requirements and machine designs. The relay integrates two delay-on de-energization safety outputs with adjustable release times, supporting controlled shutdown of machinery where run-down time is required. Its slim 45 mm housing and integrated screw terminals enable efficient installation in space-constrained control cabinets.
Key Features
- PNOZ X Series Safety Platform: Built on the proven Pilz PNOZ X architecture to ensure consistent safety performance and standardized integration.
- Flexible Safety Input Wiring: Supports 1- or 2-channel input configurations with optional short-circuit detection to match different risk levels.
- Multiple Immediate Safety Outputs: Provides 3 normally open safety contacts for direct control of contactors and safety circuits.
- Dual Time-Delayed Safety Outputs: Includes 2 normally open delay-on de-energization contacts with adjustable delay times from 0.1 to 30 seconds in 12 defined steps.
- High Electrical Load Capacity: Safety contacts are rated up to 8 A at 240 VAC or 24 VDC, supporting direct switching of industrial loads.
- Compact Cabinet Design: Narrow 45 mm width allows high-density mounting in control panels with limited space.
- Industrial Screw Terminals: Fixed terminals support conductor sizes from 24 to 10 AWG for secure, vibration-resistant wiring.
The 774540 delivers the reliability and precision required for emergency stop and safety gate monitoring with controlled shutdown timing in industrial safety systems.
