1. Ethernet-Enabled Safety Controller Overview
The Schmersal PSC1-E-24-SDM2-2 is an advanced programmable safety controller engineered for Industry 4.0 automation environments requiring robust data logging and network integration. Featuring a 120mm DIN-rail housing with IP20 protection, this device combines local safety I/O with dual SD card slots (SDM2-2 suffix) for audit trail storage and project backup. Certified to ISO 13849-1 PL e (Category 4) and IEC 62061 SIL 3, it operates at 24V DC ±15% within -25°C to +60°C. The integrated dual-port Ethernet switch supports PROFINET/PROFIsafe F-communication, while the ARM Cortex-M7 processor executes safety logic with ≤15ms scan time. Integrated diagnostic LEDs and USB-C programming port enable rapid commissioning via PSC1-Soft software. Designed for automotive, pharmaceutical, and food processing applications, it centralizes safety logic while providing SIL 3-compliant data logging for regulatory compliance.
