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.

Features

• Direct Operation from any Line Voltage with the Use of an External

Resistor

• Externally Adjustable Time Delay

• Externally Adjustable AC Voltage Sensing Level

• Logic Level Compatibility

• Safety and Regulatory Approvals:

♦ UL1577, 2,500 VACRMS for 1 Minute

♦ DIN−EN/IEC60747−5−5, 630 V Peak Working Insulation Voltage

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
