Product Description

Introduction
LKS functional safety PLCs are the first set of dual-rack redundant safety PLCs developed by HollySys. They passed the SIL2 certification of TÜV SUD and comply with IEC61508, IEC61511 and EN50128, EN50129, EN50126 and IEC61784-3 standards. They adopt the latest electronic technology and single-loop diagnostic architecture (1oo1D) design. LKS functional safety PLCs can be applied to safety-related systems requiring a safety integrity level of SIL2 or below, such as Emergency Shutdown (ESD) system, Process Shutdown (PSD) system, and Burner Management System (BMS), Fire & Gas System (FGS), Emergency Trip System (ETS), and Gas Detection System (GDS) to provide safe and reliable solutions for different fields.
