Description

ABB Linear Actuator RSD100 (Contrac)

ABB Linear actuators:-

Linear actuators are available for rated forces in the range of 4 to 200 kN (900 to 45000 lbf) and are also very similar in terms of their design. The motor drives the internal rotary/linear conversion module located on the thrust rod. This moves the thrust rod outwards or inwards, depending on the motor’s direction of rotation.

What sets Contract linear actuators apart are the technical specifications relating to this rotary/l inear conversion, whereby ABB uses a recirculating ball unit with extremely low friction.

Integrated springs absorb any peak loads which might occur when approaching the end positions for the valve. They also, however, absorb temperature-related alterations to the length of the thrust rod or valve stem (e. g. when mounting the actuator on a superheated steam pipe).

If the actuator provides the muscles for a positioning loop, the electronic units provide the brains. These modules can be installed in the field near the actuator (IP 66) or remotely in a mounting rack (IP 20). The integrated version is available for both the smallest rotary actuator and the smallest linear actuator. In addition to the connection terminals, the following are also included: a microprocessor, a frequency converter for motor control, digital inputs and outputs, communication interfaces, and a female connector for connection to a PC, with local parameterization and diagnostics via a graphical user interface. All electronic units are supplied by the line supply (1~ AC 115 / 230 V), whatever the motor output of the associated actuator.
