» SSR-xxDA is a solid state relay DC-AC one-phase Relay
Solid state relay ( SSR ), belongs to electronic contactless switch.The main characteristics are:small control signal input, directly driving high current load. It is widely used,for example, used together with temperature control instrument, can quickly control the electric heaters.
» Advantages:
long service life,contactless,no spark,no noise,no electromagnetic interference,fast switching speed,strong anti-interference capability,reliable work, and has the advantages of small volume, vibration resistance, explosion prevention, corrosion prevention, compatible with such integrated circuit as TTL, DTL, HTL and so on. .
» Insufficiency:
Output contact is not so much as contactor,only one group; in addition,due to pressure, temperature rises quickly if the load is above 5A.So you must pay attention to heat dissipation.You can also use special solid state heat sink.
» Attention of first use:
This product can only control the resistive electrical appliances, like a series of electrical heating appliances as electric wire, electric heating pipe,and there must leave 3/2 margin of the selection current size,pay attention to heat dissipation when current is above 5A!
