The Bernard electric-actuator selection manual (Chinese, 50 pages, introduction plus selection data). Bernard is one of the world’s four major actuator manufacturers; the range spans part-turn, linear, multi-turn and spring-return types with protection from IP67/IP68 through flameproof, corrosion-resistant to nuclear grade. The intelligent ST series uses absolute encoders and microprocessor control with PROFIBUS/MODBUS/FF fieldbus support — the single entry point for specifying Bernard products.
