• LT330*-*1-D24-K Output Circuit (Sink type)
• Since the output terminals are not electrically protected, an output line might be short-cir-
cuited or a connection fault might burn the external devices and LT. Be sure to install an
applicable fuse for each output terminal if there should be the risk for the current running
over the rating.

(Example) The output delay time (OFF to ON) is 1.5µs where the output current
is DC 24V, 50mA. Install an external dummy resistor to increase the amount of
current when more responsiveness is required and the load is light.
