DESCRIPTION

The 53217 is a military SPST high power, solid-state relay. It is a light-weight device re sistant to damage from shock and vibration, and immune to contact-related problems (contamination, arcing) associated with mechanical equivalents. Transformer coupling between the input and output stages provides effective isolation up to 1000 V RMS. The Power FET output eliminates bipolar offset and minimizes output voltage drop. The control input may be driven by either CMOS or TTL logic, and the bias supply will accommodate 3.8 through 32 VDC. (See figures 1 & 2) Integral short-circuit protection with status output is provided. These units sense excessive current flow while under load or while switching, and respond by opening the output. An open-collector status output is available to indicate that the short circuit protection has been activated. The output will remain blocked indefinitely until the short is removed and the unit reset. This feature prevents damage to the controller and also averts further system failures that may be caused by the short circuit. Status line output remains on until the relay is turned off for resetting. Resetting the unit can be accomplished by recycling the input control. This device is available in a variety of quality levels from COTS to class K including any custom screening requirements. The basic data sheet part is environmentally screened to H level in accordance with Table C-IX of MIL-PRF-38534, which includes no element evaluation or QCI.

Maximum input switching frequency not to exceed 20 Hz under normal conditions, or 1 Hz if output is shorted. 2. Input transitions should be <1 ms and duration and input source should be “bounceless contact” type. 3. Inductive loads must be diode suppressed. 4. Peak current that may flow when output is shorted. 5. Devices will not tolerate “short while on” at load voltages exceeding 28 VDC.
