Ruiji-RA100/RQ100 Series

1、Overview

The new generation of intelligent RA/RQ series electric actuators can be quickly set, checked, and inquired nonvasively through an independent setter. The actuator uses a graphic dot matrix LCD display to show the working status and alarms of the actuator, such as torque, position, limit setting, etc., in multiple languages, numbers, and graphics. This greatly facilitates the user's operation and use. The actuator has automatic protection functions explosion-proof functions, and there is no need to open the electrical box cover of the working actuator in hazardous areas for adjustment, parameter inspection, and fault diagnosis. supports various communication functions such as fieldbus/industrial Ethernet/wireless, and can achieve intelligent diagnosis and maintenance functions. Due to its advanced, reliable, and operation, it is welcomed by a wide range of users and is widely used in industries such as petroleum, electricity, metallurgy, and water treatment
