Digital display instrument
Intelligent manipulator

Intelligent manipulator, also known as intelligent hand manipulator , can automatically connect the given signal of the system (or regulator) and the feedback signal of the valve position, adjust according to the deviation between the two, output the corresponding control amount, and can replace the low-power servo The amplifier directly drives the valve and can be used as a backup instrument after various regulators or computer control systems.

● Features
Automatic and manual calibration functions
Automatic to manual bumpless switching
The intelligent manipulator can have one analog control output and one on / off control output; the relay forward rotation, reverse rotation control and one analog output are suitable for various measurement and control occasions.
Multiple protection, isolation design, strong anti-interference ability, high reliability
Good software platform with secondary capabilities, can meet special functions
Advanced module structure, with powerful instrument chip, function combination and system upgrade are very convenient
