AC LINE MONITORLOGIC-OUT DEVICE
MID400
DESCRIPTIONThe 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 application 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) VDE recognized (file #102915),
– add option V (e.g., MID400V)
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
