TP3-4141A024L024M Euchner Gate Switch IP67 Emergency Stop 24VDC Euchner Magnetic Safety Switch

The Euchner TP3-4141A024L024M is a SIL 3/PLe-certified safety relay module designed for monitoring emergency stops, safety gates, and machine guard circuits in industrial automation systems. This 24VDC device acts as a configurable logic solver that processes signals from safety sensors (e.g., light curtains, interlocks) to execute controlled machine shutdowns during hazardous conditions. Unlike basic relays, it incorporates force-guided contacts (per EN 60947-5-1) to prevent unsafe cross-circuit failures. The compact, DIN-rail-mountable unit (45mm width) features LED diagnostics for real-time fault tracing and operates without software programming - jumpers enable custom configurations for start/reset logic, bypass modes, or time delays. Its zinc-plated steel housing (IP20 protection) withstands vibration in control panels while ensuring compliance with global machinery safety directives.

• Safety Ratings: SIL 3 (IEC 62061), PL e (ISO 13849-1 Cat. 4), PLe (EN ISO 13849-1)
• Voltage Range: 24V DC ±10% (21.6-26.4V DC) with reverse polarity protection
• Contact Configuration: 3 Safety Channels (K1/K2/K3): 4 N/O + 2 N/C force-guided contacts; Auxiliary Contacts: 1 N/O (semiconductor)
• Switching Capacity: 6 A (AC-15) / 8 A (DC-13) per contact
• Response Time: ≤100 ms (emergency stop signal processing)
• Mechanical Life: 10 million operations at max. 1,800 operations/hour
• Ambient Temperature: -25°C to +55°C (UL Class 1 Div 2 compliant)
• Diagnostic Coverage (DC): >99% (IEC 62061 Annex D)
• Connection: Spring-cage terminals for 0.25-2.5 mm² wires

• Automotive Assembly Lines: Monitors E-stop buttons and perimeter fencing around robotic welding cells.
• Packaging Machinery: Interfaces with light curtains and two-hand controls on palletizers and shrink tunnels (EN 62061 compliance).
• Hydraulic Presses: Enables safe tool change sequences by validating guard lock status via dual-channel inputs (OSHA 1910.217 compliance).
• Material Handling Systems: Controls conveyors or AGVs via stop-category 0 shutdown when safety mats detect personnel intrusion.
• Renewable Energy: Safeguards access to wind turbine nacelles by integrating with rotary-coded switches.

• Fault Exclusion Architecture: Redundant microprocessors with cross-monitoring detect internal failures (SCM/STM technology).
• Zero Software Dependency: Hardware-based logic via jumper settings eliminates programming errors and cybersecurity risks.
• Multi-reset Flexibility: Configurable as automatic, monitored manual, or keyswitch reset per EN ISO 13850.
• Cross-circuit Detection: Force-guided contact design mechanically blocks simultaneous NO/NC closure during welding.
• Predictive Maintenance: Amber/green LEDs flag faults (e.g., contact welding, external short circuits, undervoltage) before downtime occurs.
• Synchronization Capability: Master-slave linking for coordinated shutdowns across multi-zone safety systems via PROFIsafe/CIP Safety protocols.

• Simplified Certification: Pre-validated SIL 3 reports (TÜV Rheinland #00103676) accelerate machinery CE/UKCA marking.
• Seamless Interfacing: Integrated semiconductor output drives PLCs or indicator lamps without external relays.
• Cost-efficient Safety: Replaces multiple single-function relays - one TP3-4141A module handles E-stop + guard monitoring + reset logic concurrently.
• Lifecycle Durability: Exceeds 15-year service life with MTBF >50 years (SN 29500/IEC 61709 calculations).
• Global Approvals: UL 508 (US), CSA C22.2 No. 14 (Canada), EAC TR CU 020/2011 (Eurasia), UKCA + CE (Europe).
