Moxa 28-Port Managed Industrial Ethernet Switches Futureproof Substation Automation Systems

Sept. 30, 2022
Strengthen network security with Moxa IEC 62442-4-2 Certified Rackmount Switches

Moxa RKS-G4028 Series Gigabit Ethernet managed switches serve as foundational building blocks in power substations with up to 28 Gigabit ports to fulfill future scalability requirements, modular interfaces for flexible connector combinations, certified IEC 62443-4-2 enterprise-grade cybersecurity, and compliance with IEC 61850-3 high EMC immunity requirements.

Available in 22 designs, RKS-G4028 Series switches deliver maximum versatility with options that include: Layer 3 switching functionality, 24 VDC, 48 VDC, or 110/220 VDC/VAC dual isolated redundant power supplies, and PoE++ support for powering 90W field devices.

In addition to utilities, RKS-G4028 switches extend themselves to railway workloads due to their compliance with EN 50121-4 performance criteria for signaling and telecommunications equipment. Plus, by supporting Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 switches), and STP/RSTP/MSTP for network redundancy, combined with an operating temperature range of -40 to +75° C, RKS-G4028 switches are well-suited for the most demanding factory automation use cases.

Hardware-based IEEE 1588 PTP (Precision Time Protocol) achieves clock accuracy in the sub-microsecond range, helping IT professionals unleash new possibilities in industrial measurement and SCADA control.

Moxa developed RKS-G4028 switches according to IEC 62443-4-1 lifecycle guidelines to ensure compliance to the IEC 62443-4-2 cybersecurity international standard. IEC 62443-4-2 describes the capabilities that industrial control system components must feature including account, identifier and authenticator management; password-based authentication; public key authentication; use control; data integrity and confidentiality; as well as backup for resource availability. As a result of this certification, RKS-G4028 switches improve the security posture of industrial networks and provide deep visibility into high-risk environments where critical services are delivered.

Moxa RKS-G4028 switches support MXstudio software suite for easier, more visualized industrial network management. Moxa MXstudio provides all the tools necessary throughout a network's lifecycle in a single economical solution whether it is being used for configuration, monitoring, maintenance, or troubleshooting.
