AC Line Monitor Logic-Out Device
Features
Description
■ Direct operation from any line voltage with the use of
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.

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)
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.
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

MID400 AC Line Monitor Logic-Out Device
Electrical Characteristics
Glossary
The input of the MID400 consists of two back-to-back
LED diodes which will accept and convert alternating
currents into light energy. An integrated photo diodedetector amplifier forms the output network. Optical coupling between input and output provides 2500 VRMS
voltage isolation. A very high current transfer ratio
(defined as the ratio of the DC output current and the DC
input current) is achieved through the use of high gain
amplifier. The detector amplifier circuitry operates from a
5V DC supply and drives an open collector transistor
output. The switching times are intentionally designed to
be slow in order to enable the MID400, when used as an
AC line monitor, to respond only to changes in input voltage exceeding many milliseconds. The short period of
time during zero-crossing which occurs once every half
cycle of the power line is completely ignored. To operate
the MID400, always add a resistor, RIN, in series with the
input (as shown in test circuit 1) to limit the current to the
required value. The value of the resistor can be determined by the following equation:
