Regulations and Standards

NX-series Safety Control Units NX-SL3/SI/SO

Certification body Standards
TÜV Rheinland * • EN ISO 13849-1
• EN ISO 13849-2
• IEC 61508 parts 1-7
• IEC/EN 62061
• IEC/EN 61131-2
• IEC 61326-3-1
UL • NRAG (UL 508 and ANSI/ISA 12.12.01)
• NRAG7 (CSA C22.2 No. 142 and CSA C22.2 No. 213)
Shipbuilding Standards NK, LK

* The FSoE was certified for applications in which OMRON FSoE devices are connected to each other.

The NX-series Safety Control Units allow you to build a safety control system that meets the following standards.
• Requirements for SIL 3 (Safety Integrity Level 3) in IEC 61508, EN 62061, (Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems)
• Requirements for PLe (Performance Level e) and for safety category 4 in EN ISO13849-1

The NX-series Safety Control Units are also registered for RCM, EAC, and KC compliance.
