100W Isolated DC-DC Converter for Industrial I/O Modules & Sensors

28 Jul, 2026 11:23am

Why Do Industrial I/O Modules and Sensors Experience Communication Errors or Data Loss?

In factory automation projects, engineers often focus on PLC programming, fieldbus networks and control logic. However, unstable auxiliary power is a common but overlooked cause of I/O module failures, sensor instability and communication interruptions.

Voltage fluctuations, electromagnetic interference and harsh industrial environments can affect the reliability of field devices, resulting in inaccurate data collection, communication failures and unexpected downtime.

Providing a stable and isolated 24V auxiliary power source is therefore essential for reliable industrial automation.

Why Do These Problems Occur?

Industrial environments typically include:

Voltage fluctuations on shared 24VDC power buses.

EMI generated by inverters, servo drives and large motors.

Ground loop interference between power and control circuits.

High temperature, dust, moisture and vibration.

Different project requirements requiring flexible power configurations.

What Do Engineers Really Need?

Engineers require a power solution that offers:

Stable output during voltage fluctuations.

EMI-resistant performance.

Galvanic isolation between control and power systems.

Long-term reliability in harsh environments.

Flexible customization for different automation projects.
