DESCRIPTION
The MII 53200, 53203, and 53204 are military SPDT high power, solid-state relays. These light-weight devices are resistant to damage from shock and vibration, and are immune to contact-related problems (contamination, arcing) associated with mechanical equivalents. Optical coupling between the input and output stages provides effective isolation up to 1500 volts AC RMS. Power FET outputs eliminate bipolar offset, and minimize output voltage drop for high current capability. The control logic is CMOS compatible, and will accommodate bias supplies between 4 and 16 VDC. A TTL input driver with pull up resistor may also be used. These solid-state relays are ideal for use in military systems, or wherever high reliability, low power actuation, and light-weight are design considerations. Applications include general-purpose signal switching and electronic load control.
