MID400 Datasheet PDF

●The MID400 is an Optically Isolated AC Line-to-Logic Optocoupler. The AC line voltage is monitored by two back-to-back GaAs LED diodes in series with an external resistor. A high gain detector circuit senses the LED current and drives the output gate to a logic low condition. It has been designed solely for the use as an AC line monitor. It is recommended for use in any AC-to-DC control application where excellent optical isolation, solid state reliability, TTL compatibility, small size, low power and low frequency operations are required.

● Direct operation from any line voltage with the use of an external resistor

● Externally adjustable time delay

● Externally adjustable AC voltage sensing level

● High voltage isolation between input and output

● Logic level compatibility
