For scenarios involving frequent project diversity, varied signals, and multiple protocols, the freely combinable Edge I/O modules offer one of the most cost-effective and future-proof solutions available today.
Case Details
In industrial automation, building automation systems (BAS), energy management, and IoT applications, the uncertainty in I/O point types and quantities remains one of the biggest pain points in system design and project delivery.
- Some projects are dominated by digital inputs/outputs (DI/DO)
- Others require extensive analog inputs/outputs (AI/AO) plus RTD/TC temperature sensors
- Many involve special signals such as high-speed pulse counting, serial ports, CAN, or IEPE vibration
- Realistically, no two projects have identical I/O requirements
This is exactly why the IOy series modular edge I/O modules have gained wide adoption.
True Modularity: Build Exactly What You Need, No More Compromises
The IOy series adopts a standardized I/O module + expandable slot architecture:
- A single edge I/O host supports free combination of 1–3 IOy modules
- Each module is dedicated to one type of I/O for optimal performance
- Assemble the most suitable I/O structure based on project needs, rather than being limited by fixed models
Simply plug in the required module:
- Digital: DI / DO / Relay / Mixed DI+DO
- Analog: Current / Voltage / Differential / Single-ended
- Temperature: RTD (PT100/PT1000), TC (K/J/T/N, etc.)
- Special: High-speed pulse counting, encoder, IEPE vibration
- Communication: RS485 / RS232 / CAN
Key benefit: Eliminates point waste, functional redundancy, and forced compromises.
True Cross-Industry Coverage – One Platform for Multiple Applications
Designed from the ground up for multi-industry use, not limited to a single sector.
- Building Automation / HVAC / Energy Management DI/DO for fans, valves, actuators; AI/AO for temperature, humidity, pressure; RTD/TC for chilled/hot water; supports BACnet/IP, MQTT, Modbus TCP, OPC UA. → Ideal for BMS, EMS, and subsystem I/O expansion.
- Industrial Automation & Production Lines Remote I/O extension for PLCs; high-isolation DI/DO with strong noise immunity; pulse counting, speed detection; supports Profinet, EtherCAT, Ethernet/IP. → Perfect for distributed control, line retrofits, and equipment networking.
- Energy / PV / Storage / Power Systems Multi-channel current/voltage/temperature/status acquisition; supports IEC104, SNMP, MQTT; serial modules connect directly to smart meters and protection devices. → Especially suited for space-constrained, multi-signal sites.
- Environmental Monitoring & Specialized Sensors IEPE for vibration, noise, structural health; high-resolution ADC for fast sampling; industrial EMC, –40 to 85°C wide temperature range. → One platform handles both standard and high-end sensing needs.
One Hardware Platform, Multiple Industrial Protocols
Beyond simple I/O acquisition, IOy is a true edge computing platform. Depending on the host model, it can function directly as:
- BACnet/IP Edge I/O
- MQTT Edge I/O
- Modbus TCP Edge I/O
- OPC UA Edge I/O
- SNMP / IEC104 / Profinet / EtherCAT I/O
The same IOy modules can enter different system ecosystems simply by swapping the host.
For integrators: Unified hardware, differences handled via configuration. For maintenance teams: Low learning curve, high consistency.
More Flexible Than Fixed I/O, Faster Than Custom I/O
Traditional extremes:
❌️Fixed models → Mismatched points, redundancy, complex inventory
❌️Deep customization → High cost, long lead time, poor reusability
IOy strikes the perfect balance:
✅️Standard modules + free combination
✅️No customization needed for precise matching
✅️Adapt to changes by simply replacing modules
Particularly ideal for multi-project integrators, solution providers, and long-lifecycle systems.
Industrial-Grade Reliability for 24/7 Operation
Fully validated for industrial environments:
- EMC/EMI Level 3
- ESD/EFT/Surge protection
- –40 to 85°C wide operating temperature
- 2kV I/O channel isolation
- Hardware watchdog + embedded Linux
Conclusion: IOy – Edge I/O Designed for Real Projects
The core value of the IOy series lies in its combinability:
- Modular design copes with changing requirements
- Unified platform covers multiple industries
- Standardization dramatically improves delivery efficiency and long-term sustainability
For scenarios involving frequent project diversity, varied signals, and multiple protocols, the freely combinable IOy edge I/O modules offer one of the most cost-effective and future-proof solutions available today.
