The EAS822 is a microprocessor-controlled electronic unit designed for continuous control of Contrac actuators PME120-AN and LME620-AN. It operates on a power supply of either 115 V AC or 230 V AC and utilizes a frequency converter principle for motor control. The unit features a conventional signal interface supporting 0/4 to 20 mA and 24 V signals, along with digital communication capabilities via RS232 and HART protocols. This electronic unit provides additional functionalities such as a process controller, maintenance computer, and programmable characteristics. It allows for simple configuration and parameter setting through a graphical user interface. The EAS822 is capable of torque and speed variation, ensuring reliable continuous positioning with short response times. It is designed to maintain high positioning accuracy and sensitivity, contributing to effective control quality and extended actuator lifespan.
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.
