ABB-Electrical ​rotary actuator RHD16000 (Contrac)

The ABB RHD16000 Rotary Actuator (Contrac) is a compact and powerful electrical actuator designed for operating final control elements that require rotary movement. Offering a rated torque of 1250 Nm (1000 lbf-ft), this actuator ensures precise and reliable continuous positioning for a wide range of industrial automation applications.

Built for durability and long service life, the ABB RHD16000 Rotary Actuator features a maintenance-free design that can last up to 10 years, reducing downtime and operational costs. Its thrust rod transfers force directly to the final control element, enhancing control accuracy and efficiency.

This actuator supports multiple control modes including continuous positioning, three-point position control, and bus control, providing flexible integration options to suit various process requirements. Thanks to its stall-proof design, it operates without the need for position- or torque-dependent shut-off, ensuring safety and reliability.

Adjustable mechanical limit stops allow for defining the exact operating range, while a handwheel is included for emergency manual operation, giving operators full control in all conditions. The actuator is compatible with ABB’s electronic units such as the medium power range EBN853 and EBS852, as well as the high power range EBN861 and EBS862, facilitating optimized process control and system integration.

The ABB RHD16000 Rotary Actuator is ideal for mounting rack installations and supports rated speeds like RHD1250-12,0 which operates between 12 to 900 seconds per 90°. Its operating angle ranges from a minimum of 35° to a maximum of 300°, covering diverse application needs.

Engineered for precision, durability, and ease of use, the ABB RHD16000 Rotary Actuator is a trusted solution for industries requiring high-performance rotary actuation in automated control systems.
