Onsemi MID400M Logic Output Opto-couplers 8PW AC-MON DIP

Description
The MID400M is an optically isolated AC line-to-logic interface device, 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 MID400M is designed specifically for use as an AC line monitor. It is recommended for any AC-to-DC control application requiring excellent optical isolation, solid-state reliability, TTL compatibility, small size, low power consumption, and low frequency operations.

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, 5,000 VACRMS for 1 minute
• DIN−EN/IEC60747−5−5, 890 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
