In the industrial control industry, PLC/DCS systems and variable frequency drive systems are widely adopted across various sectors. The integration of control cabinets plays a crucial role in ensuring system stability and efficiency. While core components like PLCs and inverters are often prioritized, peripheral elements such as wiring accessories, relays, and safety barriers are frequently overlooked. Tiantuo Sifang, with 15 years of hands-on experience and successful project implementations, has developed comprehensive and reliable TIA integrated accessory solutions tailored to real-world application scenarios.
First, Tiantuo Sifang introduces its "revolutionary" fast-wiring terminal board for PLC/DCS cabinet systems. After years of technical refinement, this high-level technology is specifically designed for large and medium-sized DCS systems. The IO matching interface board serves as a dedicated, highly developed interface based on industry standards, control systems, and process instruments. It ensures seamless connection with the control system, eliminating uncertainties in the wiring process of PLC/DCS cabinets. This innovation supports modern industrial automation trends, offering greater convenience for system integration, operation, and maintenance.
The product integrates essential electrical accessories within the control cabinet, including switches, relays, isolators, safety barriers, terminals, and fuses. It features modular design, standard installation dimensions, and transparent component layout, making it easy to identify and manage. This approach simplifies installation, modification, and maintenance, significantly improving operational efficiency.
The fast-wiring terminal board offers high functionality at a cost-effective price. It simplifies design and wiring by using board jumping to address differences between external equipment and system card connections. By eliminating terminal strips, these boards replace traditional terminal blocks, reducing installation costs and cutting cabinet wiring time by up to 70%. They also require only half the space compared to conventional modules, and reduce commissioning and maintenance time by up to 70%. Each signal circuit includes built-in protection, eliminating the need for external switches or fuses. With LED indicators, current measurement can be done without disconnecting the circuit, making maintenance easier and more efficient.
Second, Tiantuo Sifang provides an industrial signal interface module that includes isolators, safety barriers, and surge protectors. These modules serve as secondary instruments that isolate, transmit, convert, distribute, and protect signals. Designed to connect field instrumentation with control systems, they offer intrinsic safety and surge protection, ensuring reliable signal transmission even in harsh environments.
The TS5000 series uses embedded transformers to ensure accuracy and reliability. Its unique circuit design guarantees precise signal transmission with low power consumption, resulting in minimal heat generation and extended service life. The modules feature three-layer anti-aging, anti-moisture, and anti-corrosion protection, making them ideal for offshore platforms or high-humidity areas. The advanced coating process, using imported 3M paint, enhances insulation performance and protects against environmental stressors like moisture, dust, and aging.
Tiantuo Sifang also focuses on heat dissipation design, optimizing thermal paths to ensure smooth heat transfer and enhance system accuracy and reliability. Components are manufactured using a surface-mount process, resulting in compact, lightweight designs with consistent solder joints, strong seismic resistance, and reduced electromagnetic interference.
The dual-contact technology with bus-powered application and gold-plated surface treatment (10–12 μm) ensures excellent conductivity, space savings, and ease of maintenance. This makes it ideal for complex industrial applications.
Third, for frequency conversion drive systems, Tiantuo Sifang offers specialized reactor solutions. These reactors are installed at the input or output of inverters to suppress harmonics, reduce interference, and improve grid power quality. They also help stabilize voltage fluctuations and limit impact currents, protecting the inverter from damage.
For energy feedback systems, braking resistors provide a reliable and economical solution for energy absorption, preventing motor regenerative energy from damaging inverters and servos. They allow quick braking of heavy loads, ensuring rapid stopping and improved system safety.
As a leading global supplier of intelligent manufacturing solutions, Tiantuo Sifang delivers automation control, electrical transmission, and smart manufacturing services to industrial enterprises and government clients. The company also offers Siemens industrial software and hardware products, providing a full range of services from sales and maintenance to OEM and production process solutions.
