100a Solid State Relay Single Phase

Notice for operation of solid state relays

Input control signal:

The input control frequency of AC solid state relay should not exceed 10Hz; the period for DC solid state relay to control signal should

more than 5 times of the summation of making time and breaking time of relay. When the ambient is too high, please decrease the control

current appropriately, and when the ambient is too low, please increase the control current appropriately. Try to shorten the input line

and adopt twin line or twisted pair wire to reduce the radio frequency interference. When there are contactor or automatic switch exists,

you can parallel connect capacitance or RC circuit that series connected with resistance and capacitance on the input terminal, or

series connected with electromagnetic filter and filter circuit that made by LC to prevent from error connection caused by electromagnet

interference.

Output protecting circuit:

In the actual application, non-resistance load is used often, please add corresponding protecting circuit, such as quick-acting fuse,

transient suppressing circuit (absorption circuit), voltage dependent resistor MOV and discharging appliance, etc.,
