Introduction
Solid State Relay (ABBREVIATED SSR), is composed of
micro-electronic circuits, discrete electronic devices, power
electronic power devices contactless switch control end and load
end isolation with photoelectric coupling or pulse signal
solid-state Relay input end with tiny control signals, to directly
drive large current load.
A solid-state relay is a contactless electronic switch with
isolation function, with no mechanical contact parts during the
switching process

In addition to having the same functions as electromagnetic relay,
solid state relay also has logic circuit Compatible, vibration resistance and mechanical impact resistance,
installation position unlimited, with good moistureproof, mildew
and corrosion resistance, in explosion-proof and prevent ozone
pollution performance is also excellent, small input power, high
sensitivity, small control power, electromagnetic compatibility,
low noise and high working frequency characteristics Solid state relay special solid state relay can have short circuit
protection, overload protection and overheating protection
function, and combined logic curing package can achieve the user
needs of the intelligent module, directly used in the control
system
