Electrical Rotary Actuator - On/Off
or programmable analog signal input

3003

• Direct mounting on quarter-turn valves
• Manual override standard
• Adjustable limit switches
• Multi-voltage
• Position indicator as standard

The electrical rotary actuator, Type 3003, is a compact and powerful actu- Envelope Dimensions [mm]
ator system which provides a long service life. Materials and components
have been chosen for maintenance-free operation even in aggressive
environments and ensure low thermal loading on the actuator. The modu- A
lar design offers many additional features to be added to the basic device
such as extra limit switches, potentiometers and emergency power.
With the control actuator version the input signals (e.g. 4-20 mA, 0-20
mA, 0-10 V) as well as the output signals can be programmed.
Heating resistor and torque limiter are in standard, the housing is made
of flame resistant material classified according to UL 94 V0
