MID400 - AC LINE MONITOR LOGIC-OUT DEVICE

General 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.

Key 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) 15° MAX 0.016 (0.40) 0.008 (0.20) 0.100 (2.54) TYP 0.300 (7.62) TYP 1 8 VCC.

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 application where excellent optical isolation, solid state reliability, TTL compatibility, small size, low power, and low frequency operations are required.
