單回路控制器用於多種工業設施,例如發電廠、煉油廠、石化廠、化工廠和鋼鐵廠。這些控制器從傳感器接收溫度、流量、壓力和其他類型的測量讀數,並向閥門等控制元件發送相應指令,以便將這些值保持在期望範圍內。每個控制回路都有單獨的控制器。如今,單回路控制器廣泛應用於工業領域,用於控制小型工廠設施並用作集散控制系統的備用設備。
帶報警的YS1310指示器是一款輸入指示器,可以使用兩個輸入進行報警。可同時顯示2個回路。兩個輸入均可以生成上限報警、下限報警、上上限報警和下下限報警,並且可以從總共6個接點輸出任意報警的AND連接或OR連接。
The VJ77 Parameter Setting Tool is a PC software package for setting various parameters of YS80 series rack instruments with the BRAIN communication function.

Continuous technology improvement is ongoing in the pulp & paper industry to obtain the best possible performance. The improved plant performance translates to the higher quality improvement and lower cost, and simultaneously environmental friendly plant operation.
Automated control of industrial boilers is an excellent application for YS1700 microprocessor-based loop controllers. These instruments can be programmed to perform the operations of plant master, boiler master, fuel and air control with oxygen trim and drum level/feedwater control.
In process control it is not uncommon for systems to be affected by dead times, due to material transfer times. This is evident typically in pipelines. A fluid of density ρ and flow rate w in a section of pipe A the length of d takes the amount of time τ = ρAd/w to cover the whole distance (see Figure 1).
The YSS1000 setting software (hereinafter referred to as the YSS1000) is package software to configure the functions of the YS1000 series (hereinafter referred to as the YS1000) devices. Writing and reading of parameters and user programs of the YS1000, and PID tuning and monitoring of user programs can be performed through the use of communication.
