CAUTION
Discrete VDC outputs incorporate thermal shutdown and overload protection.
The output current of a shorted output is limited to a nondestructive value. The short circuit heats the output driver, and the output will switch off. The output will switch on again if the driver leaves the over temperature condition and the user resets the output under program control. If the short circuit still exists after the output point is reset, the driver will reach the over temperature condition again and will switch off again.
Failure to follow this precaution can result in injury or equipment damage.
