Moxa NPort IA5450I-TB-G2-T – 4-Port Industrial Device Server with 2 kV Isolation, Terminal Block Connectors, Dual Ethernet, and Extended Temperature Range

The NPort IA5450I-TB-G2-T connects up to four isolated RS-232/422/485 serial devices
to Ethernet networks via terminal block connectors and dual Ethernet ports.
With 2 kV isolation and −40 to 75 °C operation, it ensures secure,
vibration-resistant, and reliable communication in industrial systems.

  • 4 isolated serial ports RS-232/422/485 with 2 kV optical isolation
  • Terminal block connectors for secure, vibration-resistant wiring
  • Dual Ethernet ports for redundant or cascade network topologies
  • Wide-temperature range −40 to 75 °C for harsh environments
  • Security HTTPS, TLS/SSL, SNMPv3, AES/RSA encryption; IEC 62443-4-1 compliant

Ideal for substations, control panels, and automation networks requiring isolated,
redundant serial-to-Ethernet connectivity with long-term reliability and security.
