Configurable, microprocessor-controlled actuators
– Supply voltage: 24 V AC/DC, 230 V AC, 400 V AC 3~
– Position setpoint: 4-20 mA, 0/2 -10 V
– Actual-position feedback: 4-20 mA, 0/2 -10 V
– Limit switching is torque-dependent in closing direction and stroke-
dependent in opening direction.
▪
3-point actuators
– Supply voltage: 230 V AC, 400 V AC 3~
