The PT-508-MM-SC-HV is a rugged 8-port managed switch designed for substations that require high-voltage, redundant power. It provides 6x copper Fast Ethernet ports and 2x multi-mode SC fibre uplinks, supporting fibre runs up to 4 km.
With IEC 61850-3 and IEEE 1613 certification, the switch withstands EMI, surges, vibration, and harsh electrical environments. Network redundancy is ensured by Turbo Ring and Turbo Chain (<20 ms recovery) and by standards-based RSTP/MSTP protocols.
The HV model features dual isolated 110/220 VDC/VAC power inputs, providing redundancy across universal substation supply architectures. With an operating range of -40 to 85°C, it is suitable for demanding outdoor and indoor substation applications.
Advanced Layer 2 management includes VLANs, QoS, IGMP snooping, EtherNet/IP, and Modbus TCP. Security measures include IEEE 802.1X, SSH, HTTPS, SNMPv3, and RADIUS/TACACS+. Management is flexible via web, CLI, Telnet, Windows utility, and ABC-01/02 backup.
DIN-rail and wall-mounting options make installation simple. The PT-508-MM-SC-HV is ideal for extending substation Ethernet networks with reliable fibre uplinks and redundant high-voltage supply resilience.
