Q1
Which signal types can ABB AI531 measure?
AI531 supports voltage, current, resistance, Pt100, Pt1000, Ni1000, Cu50 and J, K, T, N and S thermocouple ranges. Configure each channel for the connected sensor.
Q2
Which terminal unit is required for ABB AI531?
ABB specifies TU515 or TU516. Select the screw- or spring-terminal version required by the panel and preserve the original channel wiring during replacement.
Q3
Can ABB AI531 channels be used as digital inputs?
Yes. ABB documents a 24 V digital-input mode for the analog channels. The input threshold and delay must be configured for the application.
Q4
How should ABB AI531 be matched to an existing temperature sensor?
Confirm sensor type, two-, three- or four-wire connection, measuring range, compensation and channel parameterization before transferring the wiring.
Q5
Is an XC version available for ABB AI531?
Yes. ABB lists AI531-XC as a separate active extended-condition module. Environmental qualification and the complete configuration must be checked before substitution.
Q6
What information should accompany an ABB AI531 inquiry?
Provide the complete model, terminal-unit type, signal range for every used channel, sensor wiring, quantity, destination and delivery date for a precise manual and 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. We now complete more than 30 orders per month, with an average monthly transaction value of approximately USD 3 million. We have established long-term partnerships with nearly 30 customers from different countries and welcomed almost 40 international customers to visit our company.
Since our company was founded, we have served every customer with sincerity and professionalism.
