YD***0 distributed micro-computer automation device is in
accordance with requirements of integrated automation with voltage
*5kV and below. With adoption of active power filter technology,
large LCD screen and Chinese version database, multi-layer SMT
surface mount technology, strong and weak current separation, it
has advantages of high precision, strong anti-interference,
anti-vibration, and can work under conditions of high temperature,
high humidity, low temperature and dusty area.The series devices
are equipped with distributed low-current earthing wire-selecting.
