Common Precautions
!WARNING
Be sure to turn OFF the power when wiring the Relay, other-
wise an electric shock may be received.
!WARNING
Do not touch the charged terminals of the SSR, otherwise an
electric shock may be received.
!Caution
Do not apply overvoltage or overcurrent to the I/O circuits of the
SSR, otherwise the SSR may malfunction or burn.
!Caution
Be sure to wire and solder the Relay under the proper soldering
conditions, otherwise the Relay in operation may generate ex-
cessive heat and the Relay may burn.
Typical Relay Driving Circuit Examples
Use the following formula to obtain the LED current limiting resis-
tance value to assure that the relay operates accurately.
Use the following formula to obtain the LED forward voltage value
to assure that the relay releases accurately.
Protection from Surge Voltage on the Input
Terminals
If any reversed surge voltage is imposed on the input terminals,
insert a diode in parallel to the input terminals as shown in the fol-
lowing circuit diagram and do not impose a reversed voltage value
of 3 V or more.
Surge Voltage Protection Circuit Example
Protection from Spike Voltage on the Output
Terminals
If a spike voltage exceeding the absolute maximum rated value is
generated between the output terminals, insert a C-R snubber or
clamping diode in parallel to the load as shown in the following
circuit diagram to limit the spike voltage.
Spike Voltage Protection Circuit Example
Unused Terminals (6-pin models only)
Terminal 3 is connected to the internal circuit. Do not connect
anything to terminal 3 externally.
Pin Strength for Automatic Mounting
In order to maintain the characteristics of the relay, the force
imposed on any pin of the relay for automatic mounting must not
exceed the following.
In direction A: 1.96 N
In direction B: 1.96 N
