This backwards compatibility is for legacy actuators on a site that have non-integral starters (known as “SyncroSET”). Customers can manage obsolescence concerns by replacing legacy actuators with the latest intelligent actuator platform. IQ3 Pro SET allows access to the many benefits a IQ3 Pro brings to modern plant and network design, operation and maintenance, ensures continuous reliability, connectivity and performance, and offers advanced IQ3 Pro functionality. It is compatible with existing site cabling and control systems, so there is no need for new cabling and associated costs. There is minimal downtime during upgrades. Inserting IQ3 Pro technology into a legacy system also brings the benefits of improved connectivity and service support.
