The PT-508-MM-ST-48 is a managed Fast Ethernet switch combining 6x 10/100Base-T(X) copper ports with 2x 100Base-FX multi-mode ST fibre ports. It is designed for substation automation, supporting fibre uplinks up to 4 km.
The unit is certified to IEC 61850-3 and IEEE 1613, ensuring high EMC immunity and rugged reliability in the face of surges, vibration, and harsh electrical conditions. Redundancy features include Turbo Ring and Turbo Chain (<20 ms recovery time), as well as RSTP/MSTP.
With dual isolated 48 VDC power inputs, the switch offers redundant supply resilience for utility and industrial systems. Operating in -40 to 85°C conditions, it is suitable for deployment in outdoor and indoor substation environments.
Advanced functions include VLANs, QoS, IGMP snooping, EtherNet/IP, and Modbus TCP. Security measures cover IEEE 802.1X, SSH, HTTPS, RADIUS/TACACS+, and SNMPv3. Management is supported via web, CLI, Telnet, Windows tools, and ABC-01/02 backup devices.
DIN-rail and wall-mounting options make installation straightforward. The PT-508-MM-ST-48 is a reliable choice for extending substation networks with ST fibre redundancy and resilient 48 VDC dual power support.
