FEATURES
1. So slim with 9 mm .354 inc h thickness
The thin type (45 mm long
×
24 mm high
×
9 mm wide) (1.772
×
.945
×
.354 inch)
permits high density mounting.
2. Excellent in noise resistance
Since the input and output are insulated
by the photo TRIA C coupler, the noise on
the output side is not f ed back to the input
side.
3. Snubber circuit integrated
The snubber circuit is integrated to pre-
vent malfunction caused b y the r apid rise
of the voltage on the output side , such as
inductive load and noise.
4. Zero-cross and nonzer o-cross types
are available.
The zero-cross type generates minimal
noise by suppressing occurrence of r adio
frequency interference (RFI) and electro-
magnetic interference (EMI).
The nonzero-cross type features a short
operation time which permits phase control.
5. High dielectric strength: 3,000 V AC
(between input and output)
6. Two kinds of terminals distance are
av ailable. (5.08 mm and 7.62 mm) (.200
and .300 inch)
7. High reliability, long life and mainte-
nance-free
TYPICAL APPLICATIONS
Most suitable as driv ers f or small siz e A C
motors, solenoids, solenoid valves and so
on.
1. Copying equipment
2. Air conditioners
3. Industrial equipment such as NC ma-
chines, sequencers, robots and so on

NOTES
1. When used for the load less than rat-
ed
In case of the load current less than rated,
malfunction may result from the residual
voltage across the both ends of the load
even if the solid state relay is turned off.
Use a dummy resistor as a countermea-
sure.
The total of the current through the resis-
tor and the load current must exceed the
min. rated load current.
In case the dummy resistor is not used,
keep in mind that the residual voltage be-
comes as follows:
Example:
For the inductive load by the 20 mA load
current and the 200 V AC load voltage, the
load impedance becomes 10 k Ω and
Ve/V = 14% is estimated from the right
above graph. Accordingly, the 28 V volt-
age remains across the both ends of the
load when the solid state relay is turned
off.
• Characteristics of load impedance vs.
Residual voltage
2. Solder the terminals within 5 sec-
onds at 260°C 500°F .
3. when the terminal is bent
Care shall be taken neither to apply me-
chanical stresses to the mold area of the
solid state relay nor to bend the terminal
45 degrees or more.
