Abstract : A new concept of "integrated relay," tentatively abbreviated internationally as "IR," is proposed. This concept integrates data transmission, processing, and intelligent functions, significantly reducing the size and space occupied by relay groups by integrating separate relays. Using a standard communication interface, a PLC can be connected to over 1000 integrated relays with only 3 wires. Standard cable plugs eliminate manual wiring and numbering, greatly simplifying installation. During operation, the controller can monitor the working status of each integrated relay channel at any time via the communication port. Keywords : Integrated relay; Standard communication interface; Intelligentization 1 Introduction Integrated circuits (ICs) are among the greatest inventions of the 20th century. They transformed bulky, power-consuming, slow, and unreliable electronic computers into personal computers and laptops, made space shuttles and complex control systems a reality, and enabled the rapid development of internet communication… Today, the development of integrated circuits is even more rapid, with the integration level of a single chip approaching 1 GHz (1 billion transistors), and manufacturing processes shrinking to 90 mm (nanometers). In various control systems, single-chip microprocessors, industrial PCs, dedicated controllers, and programmable logic controllers (PLCs) have become core components, with PLCs being the most widely used. As PLCs provide switch outputs, their inherent motor control is limited, often requiring intermediate relays to extend their driving capability. It's common for a complex electrical control system to use dozens, hundreds, or even thousands of relays. Therefore, the wiring between PLCs and relays is extensive, resulting in a large workload and tedious verification of wiring and wire numbers, making electrical circuit checks during maintenance extremely inconvenient. For example, a PLC with 1000 outputs (actually 1024) requires at least 1024+2 wires between the PLC and relays (two of which are power lines), and all wiring must be done manually, ensuring accuracy. All single-chip microprocessors, industrial PCs, dedicated controllers, and programmable logic controllers (PLCs) are composed of integrated circuits and large-scale integrated circuits (LSIs), forming the most complex yet smallest control cores. Relays, on the other hand, have remained largely unchanged for over 100 years, still being discrete devices. While their function in control systems is relatively simple, they occupy a very large space. Integrating relays would further miniaturize the entire control system, improve reliability and control performance, and significantly reduce manual wiring and maintenance. More importantly, such integrated relays would inevitably lead to the emergence of a new type of electrical product, establishing new product standards to ensure compatibility with PLCs, industrial PCs, and other controllers.
