541060 - Dual Safety Channels E-Stop - SIL 3 Metal Machine Safety Relay
1. Product Overview
The Pilz PNOZ X2.1P (541060) is a configurable safety relay designed for versatile machine guarding applications. This compact DIN-rail module combines dual-channel safety inputs with programmable logic functions for emergency stops, gate monitoring, and light curtain integration. Featuring force-guided contacts certified to ISO 13849-1 PL e (Cat. 4) and IEC 62061 SIL 3, it ensures reliable shutdown of hazardous machinery. The unit operates at 24V DC with screw terminal connections and includes LED status indicators for power, fault, and output status. Its IP20-rated polycarbonate housing supports temperatures from -25°C to +55°C, making it suitable for control cabinets in manufacturing, robotics, and material handling systems. The integrated startup test function automatically validates contact integrity upon power-up.
