Electronic unit

EAN823

Microprocessor-controlled electronic unit with integrated frequency converter for continuous control of electrical actuators.

Overview

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.

Data

General specifications:

Conventional signal interface (0/4 to 20 mA / 24 V)

Digital communication via HART and PROFIBUS DP

Additional functions

– Process controller

– Maintenance computer
