Product Description
Product Overview
The fine and small intelligent modules are widely used in petroleum, chemical industry, electric power, metallurgy, pharmacy, paper making, energy, water treatment, shipping, textile, food processing, building automation and other fields. At the same time, it has many advantages, such as small volume, light weight, beautiful appearance, unique and compact structure, easy installation, small operating torque, convenient operation, digital display valve position, no maintenance, safe and convenient use, etc.
Product advantages
Waterproof performance: non through magnetic induction is adopted for the key part, double sealing rubber ring is adopted for the lens part, and sealing rubber ring and waterproof joint are adopted for the shell and external junction box to reduce the possibility of water ingress from the outside.
Access mode: the non intrusive access mode without opening the cover is adopted to reduce the possibility of water ingress into the box caused by incorrect operation of on-site workers.
Integrated intelligent switch: integrate the adjustment of intelligent switch to reduce the pressure of purchasing and stocking. (Password is required for switching modes)
Encryption mode: to prevent misoperation of field workers, which may lead to error of module parameters and damage of valve body.
Precision: high precision, up to 1% precision, with basic error no more than 1%
Module self-protection: automatic phase discrimination and commutation function, power input phase loss detection, motor overheating, instantaneous turnover, power failure, overload fault alarm, current input and output overvoltage and overcurrent protection, anti-interference protection of all models
Customizable: special voltage, extended field bus (Modbus Rtu, Profi bus communication protocol, special protocol), input and output signals, shape structure, special module, English module
