Moxa NPort IA5250I-G2 – 2-Port Industrial Device Server with 2 kV Isolation and Dual Ethernet Ports

The NPort IA5250I-G2 connects isolated RS-232/422/485 serial devices to Ethernet networks
using dual Ethernet ports and redundant DC power inputs. With 2 kV isolation,
Modbus Gateway support, and TLS-secured management, it ensures secure and reliable communication.

  • 2 isolated serial ports RS-232/422/485 with 2 kV optical isolation
  • Dual Ethernet ports for redundant or cascade configurations
  • Security HTTPS, TLS/SSL, SNMPv3, AES/RSA encryption; IEC 62443-4-1 compliant
  • Modbus Gateway converts Modbus RTU/ASCII to Modbus TCP
  • Industrial-grade design Dual 12–48 V DC inputs, −40 to 75 °C operation, IP30 housing

Ideal for power, utility, and transportation applications requiring isolated,
redundant, and secure serial-to-Ethernet connectivity.
