Compared with traditional actuators, this split-type actuator has no changes in its installation dimensions and system wiring, and is highly interchangeable by adjusting the "zero" and "full" potentiometers, it can output a 4-20mA DC signal.
The difference is that the position transmitter is sent to the positioning board for processing by a special split connecting cable. The actuator and control unit are connected separately through a special connecting cable. Since the protection level of the connecting cable is IP67, it effectively solves the problem of sealing afier split connection. The two ends of the connecting cable are fixed with plug-in terminals, which is easy to disassemble and assemble.
The control part is far away from the work site, and there is no signal attenuation within 100m of the dedicated connecting cable, so it can work normally. Since most components are in corporated into the control unit, and the control part is installed in a location with relatively good environmental conditions, the reliability of the operation of electronic components is greatly improved, and the failure rate is also significantly reduced. The separation of the control unit makes maintenance and debugging extremely convenient, especially for actuators instaied in harsh and dangerous environments.
Maintenance personnel only need to operate the actuator, adjust the valve position, switch limit, etc at the installation position. This is not only simplifies the maintenance and debugging work and reduces the workload, but also ensures the safety of maintenance personnel.
