Key Features and Benefits
Redundant Safety Architecture
The
034STN1-01-300-R incorporates dual-channel safety inputs with forced-guided contacts, eliminating single points of failure. This design ensures that safety signals (e.g., from emergency stop buttons or light curtains) are verified by both channels before triggering a shutdown, reducing the risk of false alarms and ensuring fail-safe operation. In critical applications like robotic workcells, this redundancy is vital to preventing unintended machine activation.

Flexible I/O Configuration
With 3 input channels (including one auxiliary input for non-safety signals) and 6 output contacts, the 034STN1-01-300-R adapts to diverse system requirements. It supports both normally open and normally closed safety devices, allowing integration with existing sensors and switches without additional adapters. This flexibility simplifies system design in mixed environments, such as assembly lines with multiple safety zones.
Advanced Diagnostics
Equipped with LED indicators for power, input status, and fault detection, the 034STN1-01-300-R provides real-time visibility into system health. It identifies issues like wiring faults, open circuits, or overloads, enabling technicians to troubleshoot quickly. This reduces downtime in high-throughput facilities, where even short interruptions impact productivity.
Wide Compatibility
Designed to work with standard safety devices—including emergency stop buttons, safety gates, and pressure-sensitive mats—the
034STN1-01-300-R integrates seamlessly with PLCs and control systems. It supports safety-related communication protocols, ensuring coordination with higher-level automation networks in smart factories.

Warranty and Compliance
Backed by a 2-year warranty, the 034STN1-01-300-R is certified to EN ISO 13849-1 (PLd) and IEC 61508 (SIL 2), meeting global safety regulations. Our technical team offers pre-sales support for system validation and after-sales assistance for installation and calibration, ensuring compliance with industry-specific standards (e.g., automotive ISO 26262).
