采用现有ＳＴＤ工控机各功能模板构成以电液比例控制为主的大、中型电液传动及控制系统控制装置。用ＳＳＲ（固态继电器）模板取代传统的比例控制放大器和Ｄ／Ａ单元，使得控制装置的结构简单，可靠性好，研制周期短．成本低廉。
Adopting the existing function templates of the industrial control computer of the STD to form a large and medium-sized electro-hydraulic transmission and control system control device mainly based on the electro-hydraulic proportional control. Replacing the traditional proportional control amplifier and D / A unit with the SSR (Solid State Relay) template makes the control device simple in structure, good in reliability and short in development period. low cost.
