The IS series of open-loop control system with intelligent electric actuators, IS applicable to linear motion valves in the valve, globe valve, gate valve, throttle valve, diaphragm valve, gate, etc..
Can the characteristics of the electric actuator:
A high level of integration, the integration of non-invasive design
Large-scale digital integrated chip, high intelligence, powerful, high precision control.
Mechatronics design, lightweight and beautiful, the executing agency functions, parameter setting, commissioning and on-site electric operation by hand-held infrared remote control settings without opening the box.
LCD and operational functions in place
The IS series actuators with LCD display, intuitive understanding of the executive body of the valve position, operating status, fault alarm and other information through the image of the logo and symbols, full Chinese menu at a glance.
Site operation using a Hall sensor knob, and convenient place to open and close, stop and on-site, remote control conversion, to solve the switch lifetime limitation, to make the site more accurate and reliable control.
Manual / electric switching device
Manual operation is required, simply press the handle of a manual / electric switch to the manual position and then release to manual operation. When the power is running, the implementing agency is automatically returned to the electric state.
Precise itinerary electronic positioning system
Electronic positioning to replace the traditional mechanical limit, high accuracy grade, long life and high reliability.
(4) Automatic detection and fault diagnosis
The IS series executive body has a powerful error detection alarm system, able to detect the operating circuit at any time during operation, in the event of failure, the electric operation of the implementing agencies will be banned, also issued in situ and remote alarm signals and visually show the cause, allows the user to troubleshoot and restore the normal work of the implementing agencies.
5 fieldbus control
IS support communication protocols such as Profibus, Modbus, convenient access fieldbus control networks, the implementation of the organization's control and status signals can be transmitted over the network, reducing cabling costs.
(Note: The standard bus communication function, optional)
Intelligent electric actuator functions
Travel limit protection function
Open place, customs in place, open process, and clearance process, the implementing agency is running the half-way limit
Torque limit protection function
Off torque, held a moment, trip over torque
Status query function
Stop / site / remote locations, on-site open / closed / vacancy inquiries, distant or without switches and signals to maintain the distance with or without the ESD signal, the distance with or without automatic control signal, remote automatic control current value, the availability of bus signals
Implementing agencies alarm function
Power phase, the motor overheating and proportional control signal is lost, the executing agency internal fault, over-torque alarm, the stall alarm, valves, steering error, the valve position error, there is the ESD signal
