The SD series electric actuator manual provides overview, specifications, operation, adjustment, maintenance and storage instructions.
The SD series electric actuators are terminal control devices for industrial process measurement and control systems, converting control signals into angular or linear motion to operate valves and other regulating mechanisms. The manual describes three product types – angular travel, multi‑turn and linear travel – and two installation methods, direct flange or base mounting.
Key sections cover usage conditions, technical performance (power supply, environmental limits, protection functions), operation and adjustment procedures (LCD menu, remote controller, Modbus communication), maintenance guidelines, storage requirements, and warranty information. This manual is written in Chinese.
