EBN853 / EBN861
Electronic unit for field installation (Contrac)
Introduction
EBN853
EBN861
The electronic unit builds the interface between
the actuator and the control system.
During continuous positioning, the electronic unit
varies the motor torque continuously until the
actuator force and the control valve force are
balanced.
High response sensitivity and high positioning
accuracy with short positioning time ensure an
excellent control quality and a long actuator life.
For the control of Contrac control
actuators in potentially explosive
atmospheres
