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 of the MID400 are:1)direct operation from any line voltage with the use of an external resistor; (2)externally adjustable time delay; (3)externally adjustable AC voltage sensing level; (4)high voltage isolation between input and output; (5)compact plastic DIP package; (6)logic level compatibility; (7)UL recognized (File #E90700) ; (8)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.

The absolute maximum ratings of the MID400 can be summarized as:(1)high level output voltage:7 V;(2)storage temperature range:-55 to 125;(3)supply voltage:7V;(4)operating temperature:-40 to 85;(5)RMS current:25mA;(6)DC current:±30 mA.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 diode-detector 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 5 V 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.
