Why Moxa

1. Proactive
Our remote I/Os feature event-driven push and Click&Go Plus Logic to move beyond polling, reducing host reliance and streamlining IT/OT integration.


Event-driven push technology
With push-type communication, remote I/Os send data only when changes occur, significantly reducing unnecessary network traffic. Unlike pull-based systems that constantly poll devices, this method enables faster system responses and lowers overall bandwidth usage. More importantly, by offloading routine data handling from the host system, push communication helps free up computing resources, allowing the upper system to focus on higher-level applications and real-time analysis.
Supported Models:
ioLogik E1200 Series, ioLogik 2500 Series


Intuitive Click&Go Plus logic
Moxa’s Click&Go Plus Logic enables smart, front-end control logic by executing event-based actions directly on the device—eliminating the need for constant communication with a host. You can configure logic rules using an intuitive graphical interface with simple if-then-else conditions. By processing logic at the edge, devices react instantly to field events and reduce host dependency to boost overall efficiency.

ioLogik 2500 Series
2. Easy to Use
Effortless setup with front wiring and daisy-chained Ethernet simplifies installation and lowers effort, cost, and complexity.


Front-wiring design
The front-facing wiring design makes installation easier and more efficient by allowing direct access to terminals. This design not only simplifies wiring but also helps save over 50% of the required DIN-rail installation space, making it ideal for compact control panels.
Supported Models:
ioLogik E1200 Series, ioLogik R1200 Series, ioLogik 2500 Series, ioThinx 4510 Series


Dual LAN ports for daisy-chain networks
With two built-in LAN ports, devices can be directly connected in a daisy-chain configuration without needing an external switch. This simplifies network architecture, reduces wiring complexity, and lowers both installation time and costs.
Supported Models:
ioLogik E1200 Series, ioThinx 4510 Series


User-defined Modbus address
The ability to modify Modbus addresses allows the device to fit easily into existing systems without requiring major changes to configurations. This flexibility reduces implementation effort, minimizes downtime, and ensures smoother integration with legacy equipment.
Supported Models:
ioLogik E1200 Series, ioLogik 2500 Series, ioThinx 4510 Series

Where Remote I/Os Make a Difference
1. Intelligent Transportation
From bridges to airports, Moxa’s remote I/Os ensure reliable control of outdoor systems like lighting, roadside cabinets, and field devices—using a compact, rugged design built for harsh environments.


Bridge Lighting Control System
Long-distance bridge lighting systems require energy-efficient, cost-effective, and scalable control mechanisms. Traditional star networks are insufficient for large-scale infrastructure, necessitating a robust Ethernet I/O solution for long-distance connectivity.
System Requirements
- Must reduce wiring costs across long bridge spans
- Integrates easily with embedded control systems
- Operates reliably in harsh outdoor conditions
Why Moxa
- Daisy-chain Ethernet topology reduces cabling and switch costs
- SNMP and Modbus support simplify integration with edge computing
- Rugged, compact I/O ideal for roadside or bridge cabinet installation


Airport Facility Monitoring
Airport facilities must adhere to stringent cybersecurity and data integrity regulations. Remote I/O solutions must ensure encrypted data transmissions, real-time alerts, and flexible I/O support to meet diverse monitoring needs in outdoor terminals and remote control cabinets.
System Requirements
- Must comply with national encryption policies
- Secure bidirectional communication (SNMPv3)
- Modular I/O options for diverse sensor types
Why Moxa
- Supports SNMPv3 for encrypted communication and SNMPv3 Trap for proactive data updates
- Modular design adapts to different facility monitoring scenarios
- Reliable in harsh environments from -40 to 75°C
2. Data Center
Whether monitoring temperature, integrating power meters, or upgrading legacy systems, Moxa remote I/Os offer flexible, space-saving solutions that connect smoothly to IT systems via Modbus or SNMP.


High-Density Environmental Monitoring
Large-scale data centers demand highly scalable monitoring systems to maintain operational stability. High-density installations are possible with distributed I/O deployed via Ethernet daisy-chain, avoiding complex rewiring and infrastructure upgrades.
System Requirements
- IT-based management system to monitor the data center environment
- Supports daisy-chain network for distributed installation space
Why Moxa
- SNMP support can be easily integrated into a network management system
- Built-in 2-port switch for daisy-chain network topology
- Compact size to fit into any installation space


Cost-Effective Serial Monitoring
Data centers aren’t always newly built. Many cost-conscious areas depend on their existing RS-485 infrastructure for power and environmental monitoring. These deployments require a simple, compact, and low-maintenance solution that fits into limited spaces while collecting critical signals such as ATS, UPS, lighting, fans, and HVAC data. A serial-based I/O system offers a cost-effective path to digitizing legacy systems without a complete network replacement.
System Requirements
- Using existing serial network because of cost concerns and low IP management issues
- Multiple status, e.g., ATS, UPS, light, fan, temperature, humidity, etc., to collect
- Limited installation space
Why Moxa
- Compact size with front-wiring design to minimize the installation space needed
- Industrial leading 5-year warranty


Power Meter and Sensor Integration in One System
Meeting energy transparency and efficiency demands requires data centers to integrate power meter and environmental sensor data onto a single monitoring platform. Timely data delivery and system simplification are achieved by integrating analog signals and serial Modbus meters through a secure IT-friendly protocol such as SNMPv3.
System Requirements
- Centralized monitoring for both environmental and energy data
- Integration with serial power meters (Modbus RTU)
- Simplified installation across distributed server rooms
Why Moxa
- Supports SNMPv3 Trap for secure, proactive data updates
- Built-in Modbus RTU client to collect serial power, making I/O and meters data collection via Ethernet possible
- Daisy-chain topology and front-wiring simplify deployment in tight spaces
3. Manufacturing
From factory emissions to machine status signals, Moxa remote I/Os help digitalize operations with easy installation, diverse I/O support, and seamless integration to MES or SCADA platforms.


Continuous Emission Monitoring System
Environmental regulations now require factories to submit accurate emission data every 15 minutes—or risk heavy penalties. In facilities with distributed sources operating in harsh conditions, robust data transmission and recovery systems are essential to prevent data loss and meet regulatory requirements.
System Requirements
- Must update emission data to DAHS every 15 minutes
- Zero data loss allowed—non-compliance leads to fines
- Must operate reliably in outdoor, industrial conditions
Why Moxa
- ioLogik 2500 with MX-AOPC UA ensures automatic data backup and recovery
- Active data delivery to DAHS ensures timely compliance
- Rugged, wide-temperature design ready for harsh field environments
- More cost-effective compared to traditional SCADA systems


Machine Status Monitoring
To improve OEE and lay the groundwork for smart manufacturing, factories need visibility of machine availability. Capturing tri-color tower light signals from legacy machines and integrating them into MES systems is a critical first step in this transformation.
System Requirements
- Capturing machine status from legacy equipment lacking Ethernet
- Must fit into tight spaces near tri-color light towers
- Integration with existing MES
Why Moxa
- Compact I/O design fits into tight machine enclosures
- ioLogik E1200 captures light tower status and pushes updates via MX-AOPC
- MX-AOPC supports OPC UA for seamless MES integration
