On March 31, 2009, the 12th Northeast International Instrumentation and Industrial Automation Exhibition was successfully opened in Shenyang, the industrial hinterland of Northeast China. In recent years, with the national revitalization of the old industrial base in Northeast China and the gradual deepening of the equipment manufacturing industry, the rapid development of Northeast China has provided many opportunities for Chinese automation manufacturers. APT enjoys a good reputation in the low-voltage control component market for its excellent product quality and made its debut at the Northeast Automation Exhibition shortly after joining Siemens. With a clean lineup and an atmospheric booth, APT demonstrated to customers a strong confidence in being positive against the current contrarian background.
As the drafting unit of the industry standard for indicators and buttons, APT has been brought up all the time, and the word "high quality" comes to mind. APT also lived up to expectations. In the long-term market application, it has won the trust and love of many customers in the industry. Even some manufacturers of low-voltage control components will directly choose APT products when they need to meet the needs of some high-end customers. As the impact of the financial turmoil penetrates deep into China's automation market, some small and medium-sized manufacturers are also in danger of reducing and suspending production. Users will also consider whether the after-sales and quality of the product can be better guaranteed. At this time, APT frequently dresses up and participates in well-known exhibitions in the industry with a positive attitude, conveying an attitude to users, so that users can feel APT's confidence and determination to fight against this contrarian.
At the exhibition site, APT's booth design style based on black, red and white gave people a familiar and eye-catching feeling. Under the light of the exhibition hall, the whole booth is very eye-catching. At the exhibition, APT displayed indicators and buttons, and shared APT's industrial applications and case descriptions with guests at the exhibition site. APT technical engineers came to the scene to answer questions for the guests, so that the guests can understand the wide application and value-added services of APT in various industries, which became the highlight of this exhibition, attracted many visitors to stop, and made everyone look forward to the future development of APT.

Siemens APT Relays - Selection Method for Solid State Relays
1. When selecting the solid-state relay used in the printed circuit board with small current specifications, because the lead terminal is made of high thermal conductivity material, the soldering should be carried out under the condition that the temperature is less than 250 °C and the time is less than 10S.

Features of Siemens APT Relays – AC Relays
1. Since the current through the AC electromagnetic relay is a changing alternating current, the magnetic flux in the magnetic circuit also changes with the alternation (sinusoidal law instead of straight line law). The suction force of the armature is varied between 0 and the maximum, so the suction of the AC electromagnetic relay is pulsating, variing.

Siemens APT Relays – The difference between AC relays and DC relays
1. Structural characteristics of AC relays
The coil of the AC relay is shorter, and the wire diameter is thicker, mainly because the coil is passed through the alternating current, the reactance is larger, and the thick wire diameter can reduce the internal resistance and reduce the heat generation.
