Product Description
The 802288-74D is a DRIVE BOARD SIGNAL INTERFACE MAXITRON 9000 SF that was produced by Reliance Electric. The 802288-74D is a large circuit board with many pieces to it. The card features at least thirty-three sets of jumper pins. Some of these pins have slipcovers while others do not. These slip covers can be moved to the sets of pins without them to produce a different effect across the card. The 802288-74D has one extremely tall and wide PCB mount electrolytic capacitor and two slightly smaller PCB mount electrolytic capacitor. There are four cage-like structures that stand on end (two are metal and silver and two are black with a rubbery coating). There is also a cage that forms a fence like a perimeter around a bipolar transistor. There is a crystal oscillator near this fence. The 802288-74D has forty integrated circuits on the surface. There are also many openings for other integrated circuits of various sizes to be installed. There are three yellow and two red radial ceramic capacitors. The card also has two mauve fusible resistors. In between the large components are also a series of multilayer chip ceramic capacitors and SMD surface mounted resistors. To tell the difference there is a marking next to them, “C” for capacitor and “R” for a resistor. The capacitors are also a light color while the resistors are typically black with white markings on the surface. To connect the 802288-74D use the large clip in male terminal on the side and secure it with the screw holes in each corner.
