MID400SDV

The MID400 is an optically isolated AC line-to-logic interface device. It is packaged an 8-lead plastic DIP. 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.

The MID400 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 AC voltage sensing level
• High voltage isolation between input and output
• Compact plastic DIP package
• Logic level compatability
• UL recognized (file #E90700)
• VDE recognized (file #102915), - add option V (e.g., MID400V)
