AC LINE MONITOR LOGIC-OUT DEVICE
MID400
DESCRIPTION
The MID400 is an optically isolated AC line-to-logic interface
device. It is packaged in 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 appli-
cation where excellent optical isolation, solid state reliability, TTL
compatibility, small size, low power, and low frequency operations
are required.
FEATURES
• 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
• Compact plastic DIP package
• Logic level compatibility
• UL recognized (File #E90700)
APPLICATIONS
• Monitoring of the AC / DC “line-down” condition
• “Closed-loop” interface between electromechanical elements such
as solenoids, relay contacts, small motors, and microprocessors
• Time delay isolation switch
