EBN861 Electronic Unit
Brand: ABB GroupMicroprocessor-controlled electronic unit with integrated frequency converter for continuous control of electrical actuators. Also available as explosion-proof version.
During continuous positioning the electronic unit varies the motor torque steplessly until the actuator force and the restoring process forces are balanced.
High response sensitivity and positioning accuracy ensure an excellent control quality and a long actuator life expectancy.
Features- Conventional signal interface (0/4 to 20 mA / 24 V)
- Digital communication via HART and PROFIBUS DP
- Additional functions
- Process controller
- Maintenance computer
- Programmable characteristics
- Field installation
- Housing with high protection class IP66
- Torque, speed variation and continuous positioning
