SICK — Safety Controllers
The Sick PL20M is a modular, programmable safety controller designed for flexible machine safety solutions ranging from standalone safeguards to complex multi-zone safety systems. It supports up to 128 safe I/O points via expansion modules and offers integrated safe communication protocols including PROFIsafe, CIP Safety, and EtherCAT FSoE. Configuration is performed using Sick's intuitive Safety Designer software with certified function blocks for common safety applications. The controller achieves SIL 3 (IEC 61508), PL e (EN ISO 13849-1) with diagnostic coverage exceeding 99%, and operates across a wide -25 to +55 °C temperature range.
