NPort IA5000A Series
The Moxa NPort IA5000A Series Brings Redundant Serial-to-Ethernet Connectivity to Demanding Networks
Some facilities can tolerate a brief network hiccup. Others can't, and that's exactly the gap the Moxa NPort IA5000A Series was designed to close. It takes the core function of an industrial serial device server, bridging RS-232, RS-422, and RS-485 equipment onto Ethernet, and adds the redundancy layer that mission-critical operations actually require.
You'll find this series specified in factory automation, oil and gas, power automation, industrial control, machine automation, and process automation settings, anywhere a dropped connection isn't an acceptable outcome.
NPort IA5000A Series Key Features Worth Knowing
Before choosing a serial device server, it helps to understand exactly what sets this series apart. Each feature here addresses a specific reliability or integration concern that comes up repeatedly in industrial deployments.
- Redundant Power Inputs: A second power input keeps the device running even if one source fails. This matters most in facilities where power fluctuations or outages are a regular occurrence, not an exception. This is where the series' real redundancy comes from.
- Cascading Ethernet Ports: Two Ethernet ports let multiple units be linked together, reducing the number of switches needed and simplifying wiring. This is a wiring convenience, not independent network redundancy in itself.
- RS-232/422/485 Interfaces: Support for all three major serial standards covers the majority of legacy field equipment still in service, often from one device server instead of separate hardware per interface.
- Serial Port Isolation (2 kV, on "I" models): Protects connected equipment from electrical surges traveling through the serial connection, preventing a single electrical event from damaging both the device server and whatever it's connected to.
- Operating Temperature: 0 to 60°C on standard models; -T variants extend that to -40 to 75°C for unconditioned outdoor cabinets or facilities with extreme seasonal swings.
- Enhanced Surge Protection: Built-in surge protection on serial, LAN, and power lines adds another layer of defense against voltage spikes.
- DIN-Rail Mounting: Fits directly into existing industrial control cabinets, without requiring custom installation hardware.
- Hazardous Location and Safety Certifications: ATEX, Class I Division 2, and IECEx certification for hazardous locations, UL 508 for industrial safety, and DNV for marine applications.
- Relay Output and Email Alerts: Built-in alerting notifies maintenance teams the moment something goes wrong, cutting down the time between a fault occurring and someone addressing it.
The Problem With Legacy Serial Equipment, and How This Series Solves It
Most industrial facilities aren't dealing with a single connectivity gap, they're managing an entire cabinet of serial devices that were never designed to report back to a centralized network. A PLC running RS-485 sits disconnected from SCADA. A motor drive wired for RS-232 requires someone to physically check it. Every one of these gaps adds friction to daily operations.
The NPort IA5000A Series addresses this directly, giving legacy serial equipment a reliable, redundant path onto modern Ethernet networks:
- Converts serial to Ethernet: bridges legacy equipment onto the network without hardware changes on the field device side
- Stays online through redundancy: dual power inputs keep the connection stable even when one source fails
- Built for harsh conditions: withstands extreme temperatures, vibration, and electrical noise that would compromise standard equipment
- Protects against electrical damage: serial isolation and surge protection reduce the risk of one event cascading into a bigger problem
- Built for continuous operation: designed for environments where equipment failure carries real operational costs
In practice, that reliability shows up across a recurring set of use cases:
- PLC connectivity across mixed-protocol or geographically distributed production lines
- Industrial sensor and meter networking for continuous process monitoring
- Motor drive and machine automation communication
- Barcode reader and operator display connectivity across factory floor stations
- Legacy serial device integration without full hardware replacement
- Remote serial device access at unmanned or distributed sites
Key Models in the NPort IA5000A Series
The IA5000A series spans multiple models across 1, 2, and 4 serial ports, each available with or without serial isolation and in standard or wide-temperature variants. The table below covers the part numbers most facilities choose between:
All models share the same core redundant power inputs, cascading Ethernet ports, and surge protection. The differences come down to how many serial devices you're connecting, whether your environment needs isolation, and how extreme the operating temperature gets.
Everything You Need to Know Before You Order
If you want the full technical picture before deciding, Moxa's documentation covers it. The user manual walks through setup in detail, and the quick installation guide is there if you just need to get the unit mounted and wired without digging through every page. For network settings and protocol configuration, the configuration guide breaks it down step by step, and the datasheet has the full spec sheet for anyone comparing this against other models.
Still have questions after that? That's what we're here for. A quick conversation about your equipment and environment usually settles which configuration actually fits, and getting a quote starts with exactly that conversation.
As a Moxa distributor based in Canada, we stick around past the initial order too, helping with anything that comes up during or after installation. Whether it's one unit for a single site or a rollout across several facilities, our team is happy to help you land on the right choice.
Common Questions About the NPort IA5000A Series
1. What is the Moxa NPort IA5000A?
It's an industrial serial device server that connects RS-232, RS-422, and RS-485 equipment to Ethernet networks, built with redundant power inputs and enhanced surge protection for added reliability.
2. What is the NPort IA5000A used for?
It's used to bring legacy serial devices onto modern Ethernet networks, supporting PLC communication, remote monitoring, and industrial automation networking.
3. What serial interfaces does the NPort IA5000A support?
It supports RS-232, RS-422, and RS-485, covering the three major legacy serial standards used in industrial field equipment.
4. How does the NPort IA5000A connect serial devices to Ethernet?
It receives data through its serial ports and transmits it over Ethernet using modes like Real COM, TCP Server/Client, or UDP.
5. How do I configure the NPort IA5000A?
Configuration is done through the web interface or configuration utility, with full steps outlined in the official configuration guide.
6. Does the NPort IA5000A support redundant power?
Yes. Dual power inputs keep the device running even if one source fails.
7. Do the dual Ethernet ports provide network redundancy?
Not on their own. The two Ethernet ports are mainly there for cascading, letting units share a single network connection to cut down on cabling and switch ports. The series' real redundancy comes from its dual power inputs, not the Ethernet ports.
8. Is the NPort IA5000A suitable for hazardous environments?
Yes. It carries ATEX, Class I Division 2, and IECEx certification for hazardous locations, along with UL 508 and DNV certification for marine applications.
