Overview
Moxa NPort IA5450-TB-G2 – 4-Port Industrial Device Server with Terminal Block Connectors and Dual Ethernet Ports
The NPort IA5450-TB-G2 connects up to four RS-232/422/485 serial devices to Ethernet networks
via terminal block connectors and dual Ethernet ports. It supports Modbus Gateway,
HTTPS/TLS management, and redundant power inputs for secure and reliable automation networking.
- 4 serial ports RS-232/422/485 with vibration-resistant terminal block connectors
- Dual Ethernet ports for redundant or cascade configurations
- Modbus Gateway converts Modbus RTU/ASCII to Modbus TCP
- Security HTTPS, TLS/SSL, SNMPv3, AES/RSA encryption; IEC 62443-4-1 compliant
- Industrial design Dual 12–48 V DC inputs, IP30 housing, −40 to 75 °C operation
Ideal for automation, utilities, and transport networks where secure,
redundant, and multi-port serial-to-Ethernet connectivity is required.
