Primary Main Functions
- Emergency Stop Circuit Monitoring: Continuously detects emergency stop button status; immediately cuts off all safety output loops once the emergency button is pressed to halt dangerous machine movement.
- Safety Door Interlock Control: Monitors safety gate switches on protective enclosures; equipment cannot start when safety doors are open, and power cuts off instantly during running if doors are opened accidentally.
- Dual Reset Logic Management: Supports manual reset to prevent unintended automatic restart after fault elimination, and automatic reset for simple safety scenarios to meet diverse production demands.
- Multi-Channel Safe Output Distribution: 8 independent safety contacts can control multiple actuators including contactors, valves and drive systems synchronously for complete power cutoff.
- Fault Diagnostic Feedback: The auxiliary contact transmits safety circuit fault signals to PLC for upper system alarm, fault recording and status monitoring.
- Cross-Channel Fault Detection: Built-in cross-check function for dual-channel input lines to identify wire breakage, short-circuit and wiring errors automatically.
- Wide Voltage Stable Operation: Tolerates industrial power grid voltage fluctuation, maintaining reliable safety performance under unstable workshop power supply conditions.
- Anti-Fault Contact Protection: Force-guided contacts prohibit simultaneous closing of NO and NC contacts, eliminating hidden dangers caused by contact adhesion failures.
Key Technical Features
- High-grade safety certification (SIL3 / PL e / Cat.4) satisfies strict European and global machinery safety compliance requirements for equipment export.
- Modular compact DIN rail design saves cabinet internal space, easy for integration into standard electrical control cabinets.
- Pluggable screw terminals enable fast wiring, disassembly and maintenance without removing the entire module from the rail.
- Optimized internal circuit with strong EMC anti-interference capability works steadily near inverters, servo drives and high-power electromagnetic equipment.
- Long mechanical service life up to 10 million switching cycles, adapting to 24-hour uninterrupted cyclic industrial operation.
- Clear LED status indicators display power supply, input signal, fault and relay actuation states for rapid on-site troubleshooting.
- Unified PSRclassic series platform achieves full compatibility and interchangeability of spare parts within the product family.
- Flame-retardant reinforced plastic housing delivers excellent impact resistance, dustproof and oil-proof performance for harsh workshop environments.
