东辉仪表DY2000（DX/GDX）智能D型操作器DY21DX、DY22DX、DY26DX、DY28DX、DY29DX、DY21GDX、DY22GDX、DY26GDX、DY28GDX、DY29GDX
1. 伺服放大器，手动操作和后备操作集一体的能产品，适用于作为DCS系统回路调节控制输出和智能调节器控制输出后备操作器使用。
2. 处于自动工作时本仪表相当于伺服放大器。
3. 处于手动工作时相当于手操器，通过面板上的“▲”键和“▼”键直接控制正转和反转信号输出，按面板“ENT”键可进行手动/自动切换。
4. 接受远程手动/自动切换、正转和反转信号，相当于仪表面板上的“ENT”、 “▲”键、“▼”键的功能。
5. 支持无反馈信号虚拟反馈调节。
6. 支持现场阀位标定。
7. 支持MODBUS(RTU)协议。
