The Euchner 027029 is a compact safety relay module engineered for machine-guarding applications requiring SIL 3/PLe safety integrity. Designed as part of Euchner’s modular safety system, this device monitors safety components like door switches, light curtains, and emergency stops while ensuring compliance with ISO 13849 and IEC 62061. Its robust polycarbonate housing (IP65 rated) withstands industrial environments with dust, humidity, and vibration. The relay features dual-channel redundancy with cross-circuit monitoring to detect faults such as contact welding or wire breaks. Universal 24V DC operation and pluggable screw terminals simplify integration into control cabinets, while integrated LED status indicators provide immediate visual feedback on safety circuit health.
Precision specifications define the 027029’s performance:
These parameters ensure failsafe control of safety-critical machinery worldwide.
Deployed in high-risk industrial zones, the 027029 safeguards:
The 027029 outperforms conventional safety relays through:
This reduces validation time for safety systems and prevents false shutdowns costing $50k/hour in manufacturing.
Advanced capabilities include:
Engineered for seamless interoperability with safety PLCs and networks like PROFIsafe, the Euchner 027029 delivers uncompromising protection for modern automated plants.
