The Type 3003 is a compact and powerful, long life actuator system. Materials and components have been chosen for maintenance-free operation even in aggressive environments and ensure low thermal loading on the actuator. The modular 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 (eg. 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.
