Advantages of ATO relay

Relay is also an electronic control device, which has a control system (input loop) and a controlled system (output loop), usually used in automatic control circuits. The relay is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays the role of automatic regulation, safety protection and conversion circuit in the circuit. Relays provided by ATO have the following advantages:

High sensitivity, low control power and good electromagnetic compatibility. Solid state relays have a wide input voltage range, low drive power, and are compatible with most logic integrated circuit without buffers or drivers.
It can be used for a long time. Relays have no mechanical parts, solid devices to complete the contact function, because there are no moving parts, so they can work in high vibration environment.
Capable of fast conversion. ATO relays use sophisticated components, so switching speeds can range from milliseconds to subtleties.
Integrated signal. When multiple control signals are input into the multi-winding relay in the prescribed form, the predetermined control effect can be achieved through comparison and synthesis.
Automatic, remote control and monitoring. The relay on the automatic device, together with other electrical appliances, can form a program control line, so as to realize automatic operation.

Our Mission:

In the development of ATO for more than 15 years, we always adhere to honesty, and to the high standard of modern enterprises to strictly regulate the operation of the company.
