About Us

Siesource Industrial (HK) Limited is a Hong Kong-based supplier of industrial automation parts. We supply PLCs, servo drives, motors, inverters, HMIs, sensors, I/O modules, power supplies, and other industrial control components for equipment maintenance, system integration, and industrial procurement.

Our sourcing covers established automation brands including Siemens, ABB, Allen-Bradley, Yaskawa, Schneider Electric, and FANUC.

Alongside current product lines, we also help customers locate obsolete, discontinued, and hard-to-find automation parts for existing industrial equipment.

What We Supply

Our products are used in manufacturing equipment, electrical control systems, CNC machinery, packaging lines, material handling equipment, and factory maintenance.

Main product categories include:

PLCs and I/O modules
Servo drives and servo motors
Inverters and variable frequency drives
HMIs and operator panels
Sensors and power supplies
Industrial control and replacement parts

For accurate identification, customers can send us the manufacturer, complete part number, required quantity, and a nameplate photo when available.

Current and Hard-to-Find Automation Parts

Industrial equipment often remains in service long after individual electronic components have been discontinued.

We handle inquiries for both current products and older components, including discontinued PLC modules, legacy drives, HMIs, control modules, and other difficult-to-source parts.

For older products, we check the exact part number and specification rather than assuming a newer model is a direct replacement.
