'''Tektronix [[TM500 and TM5000 mainframes|TM5000 mainframes]]''' provide power supplies and signal connections for [[TM500 and TM5000 plug-ins|TM5000 plug-ins]]. | |||
There are two dedicated, floating 25 V<sub>AC</sub> transformer windings per slot, as well as several AC and DC buses shared by all slots.<br /> | |||
For each slot, two uncommitted transistors (one NPN and one PNP) are mounted in the mainframe. These are available for the module's power regulation circuits. | |||
The signal pin connections depend on the individual modules. For details, please see the [[Media:070-2088-00.pdf|TM 500 Rear Interface Data Book]]. | |||
