A Q-B SOLID STATE RELAY AQ-B
RELAYS
UL File No.: E43149
CSA File No.: LR48894M14
• Two types available: Non zero-cross type and Zero-cross type
Non zero-cross type permits phase control and Zero-cross type
suppresses occurrence of noise.
• Slim type
The small-sized slim type (43 mm long ×9 mm wide ×24 mm high)
(1.693 ×.354 ×.945 inch) permits high density mounting to PC board.
• High dielectric strength: 1500 V AC (between input and output)
TYPES APPLICATIONS
• Copying equipment
• NC machines, sequencers, robots
• Air conditioners

NOTE • Characteristics of load impedance vs.
residual voltage
When used for the load less than
rated
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
becomes as follows:
Example:
For the inductive load by the 5 mA load cur-
rent and the 200 V AC load voltage, the load
impedance becomes 40 kΩand Ve/V = 16%
is estimated from the right above graph.
Accordingly, the 32 V voltage remains across
the both ends of the load when the solid state
relay is turned off.
