Description

The Moxa NPort IA5250-TB-G2-T is a 2-port industrial serial device server that connects RS-232/422/485 serial devices to Ethernet networks. This wide temperature model operates from -40 to 75°C and uses 2 x 5-pin terminal block serial connectors without serial isolation, making it well suited to harsh factory, utility and field automation environments.

Built on the second-generation NPort IA5000-G2 platform, it provides two 10/100BaseT(X) RJ45 Ethernet ports with built-in 1.5 kV magnetic isolation for cascading or network redundancy. A metal IP30 DIN-rail housing, 12 to 48 VDC power input, surge protection and secure operation modes such as Secure Real COM, Secure TCP Server and Reverse SSH support dependable and secure serial-to-Ethernet connectivity.

Features

- Classic Real COM mode set up in about 30 seconds with DSU-G2
- Two Ethernet ports with the same IP or dual IP addresses for network redundancy
- Cascading Ethernet ports for easy wiring
- Data encryption in secure operation modes: Secure Real COM, Secure TCP Server, Secure TCP Client, Reverse SSH, Secure Pair Connection
- Standard operation modes: Real COM, TCP Server, TCP Client, UDP, Reverse Terminal, RFC2217, Pair Connection
- Compliance with IEC 62443-4-2 Security Level 2 requirements
- One-click diagnostics and embedded traffic monitoring
- Surge protection on serial, power and Ethernet lines (IEC 61000-4-5)
- Configuration via web console, Device Search Utility (DSU), MCC Tool or serial console
- DNV, CID2, ATEX Zone 2 and IECEx certified

FAQs

Q: What serial interfaces does the NPort IA5250-TB-G2-T support?
A: Both serial ports support RS-232, RS-422 and RS-485, selectable in software, and use 5-pin terminal block connectors.

Q: What operating temperature range does this model support?
A: This wide temperature model operates from -40 to 75°C, suitable for harsh industrial environments.

Q: Does this model provide serial isolation?
A: No. This terminal block variant has no serial isolation. The Ethernet ports provide 1.5 kV magnetic isolation.

Q: How is the device powered?
A: It accepts a 12 to 48 VDC input and is housed in a metal IP30 case designed for DIN-rail mounting.

Q: Which security protocols and operation modes are supported?
A: It supports HTTPS (TLS 1.2), SSHv2 and SNMPv3, plus secure modes including Secure Real COM, Secure TCP Server, Secure TCP Client, Reverse SSH and Secure Pair Connection.

Q: Can the two Ethernet ports be used for redundancy?
A: Yes. The two Ethernet ports can share the same IP address or use dual IP addresses for network redundancy, and they can also be cascaded for easier wiring.
