SOLID STATE RELAY
AQ8-RELAYS
5. High dielectric strength: 3,000 V AC
(between input and output)
6. Two kinds of terminals distance are
available. (5.08 mm and 7.62 mm)
(.200
and .300 inch)
7. High reliability, long life and mainte-
nance-free

1. So slim with 9 mm .354 inch 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 TRIAC coupler, the noise on
the output side is not fed back to the input
side.
3. Snubber circuit integrated
The snubber circuit is integrated to pre-
vent malfunction caused by the rapid rise
of the voltage on the output side, such as
inductive load and noise.
4. Zero-cross and nonzero-cross types
are available.
The zero-cross type generates minimal
noise by suppressing occurrence of radio
frequency interference (RFI) and electro-
magnetic interference (EMI).
The nonzero-cross type features a short
operation time which permits phase control.
TYPICAL APPLICATIONS
Most suitable as drivers for small size AC
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
