The PT-508-MM-ST-HV is a hardened, 8-port managed Fast Ethernet switch designed for substation environments that require universal high-voltage power. It provides 6x 10/100Base-T(X) copper ports and 2x 100Base-FX multi-mode ST fibre ports, extending communication distances up to 4 km.
With IEC 61850-3 and IEEE 1613 certification, the switch withstands EMI, surges, and vibration. It supports Turbo Ring and Turbo Chain (<20 ms recovery across 250 switches), along with RSTP/MSTP, for a flexible redundancy design.
Dual isolated 110/220 VDC/VAC power inputs enable resilient supply configurations for substation automation systems. Operation is guaranteed from -40 to 85°C, ensuring dependable service in harsh climates.
The PT-508-MM-ST-HV supports VLANs, QoS, IGMP snooping, EtherNet/IP, Modbus TCP, and RMON for traffic control and monitoring. Security measures include IEEE 802.1X, SSH, HTTPS, SNMPv3, and RADIUS/TACACS+. Management is supported by web, CLI, Telnet, Windows utility, and ABC-01/02 backup configurators.
DIN-rail and wall-mounting support simplify installation. The PT-508-MM-ST-HV is an excellent choice for extending substation Ethernet networks with ST fibre while ensuring high-voltage redundant power resilience.
