LOAD SWITCHING
Grouped relay contacts for mixed industrial loads.
Reliable use depends on load qualification, external protection and suppression chosen for the field circuit.
01
SYSTEM FUNCTION
Load matching
Confirm resistive, lamp and inductive characteristics against the ABB relay ratings before connection.
02
SYSTEM FUNCTION
Group planning
Eight outputs share each group, so the sum of channel currents must remain within the 10 A group limit.
03
SYSTEM FUNCTION
External protection
The relay contacts have no short-circuit or overload protection and require suitable external protection.

Q1
Which voltages can ABB DO573 relay outputs switch?
ABB specifies 24 V DC, 24 V AC and 100–240 V AC applications within the documented load limits. Verify the exact load category before wiring.
Q2
How are the outputs grouped on ABB DO573?
The sixteen normally-open relay outputs are arranged in two groups of eight. Each group is limited to 10 A, with 20 A maximum for the module.
Q3
Does ABB DO573 provide short-circuit protection?
No. ABB states that the relay outputs are not short-circuit or overload protected. Provide suitable external fusing or circuit protection.
Q4
Which terminal blocks are used with ABB DO573?
ABB lists 9-pin and 11-pin TA563, TA564 and TA565 terminal-block options. Select the screw or spring wiring style needed by the installation.
Q5
Can ABB DO573 be replaced by an eight-output relay module?
Not without redesign. Channel count, group current, terminal blocks and field assignments differ, so the electrical and project configuration must be reviewed.
Q6
What should be sent when requesting ABB DO573 documentation and pricing?
Provide the full model, supply and load voltages, load types, terminal-block references, quantity, destination and delivery date for a correct quotation review.

GLOBAL COORDINATION
MILESTONE 01
2005
The Beginning
Company was founded in Xiamen, Fujian, China, in 2005 with a team of only four people. At that time, we mainly served selected European and North American markets, supplying commonly requested industrial automation products from Siemens, Allen-Bradley and Bently Nevada. Although the business was still developing and we completed relatively few orders, this period helped us build essential product knowledge and international trade experience.
MILESTONE 02
2017
A Period of Growth
By 2017, our team had grown to approximately 30 people, and we had established a warehouse for in-stock automation components. Our business expanded across Europe, North America and Southeast Asia, while our product range grew from popular models to scarce and discontinued industrial automation parts. As our product knowledge and service experience increased, we completed nearly 20 orders per month on average.
MILESTONE 03
Today
Serving Customers Worldwide
Today, Company serves customers worldwide with a professional team of approximately 60 people. Our warehouse holds a broad selection of industrial automation components, including popular products, hard-to-find parts and discontinued models.
