The Pilz 541059 PNOZ s5 is a configurable solid-state safety relay designed for Machinery Safety applications requiring SIL 3 (IEC 62061) and PLe/Cat.4 (ISO 13849-1) performance. This DIN-rail mountable unit (22.5mm width) integrates two forcibly guided N/O safety contacts (suffix 2n/o), enabling reliable emergency stop monitoring, guard door interlocking, and light curtain control.
Featuring semiconductor outputs with 24VDC operating voltage and IP20 protection, it processes safety inputs for E-stops, interlocks, or pressure mats via cross-circuit monitored channels. Self-monitoring architecture with redundant processors ensures immediate fault detection, while LED status indicators provide clear diagnostics. Certified globally including UL, CE, and CCC for worldwide industrial deployment.
