= 80mA max
D
Pin3 can be used for Either a Latching Function or Automatic Resetting Function (In Both
Overload Detection and Output Offset Detection, Either Function can be Selected)
D
Single Power Supply
D
Both Positive and Negative Output Offset can be Detected Through the Same Pin (Output Off-
set Detection Through Pin2)
D
AC Voltage can be Detected (For AC鈥揚(yáng)ower鈥揙FF Mute Through Pin4)
D
The Time Delay from Amplifier Power ON to Relay ON can be Freely Set by Selecting External
Components. (For AC鈥揚(yáng)ower鈥揙N Mute Through Pin7)
