FIG. 5D shows an example integrated chip design having voltage inputs 1330 which travel through the circuit resistor(s) 1332, pass diode 1332, through an optocoupler 1333, which is grounded 1338, thought a resistor 1334 to an output voltage measurement 1335. An analogical bus M-1 is shown connected to the output voltages 1335. In an embodiment, the resistors R1, R2, R3, R4 1331 and R5, R6 can be set to values depending upon the range of the Vin range. In an embodiment, the optocoupler effectively ensures the voltage transformation and a very high insulation between inputs and outputs.
FIG. 5E shows an example input selector system. For example, Vin 1340 enters an input selector 1341. The input selector 1341 includes a stepdown transformer 1343, a bridge rectifier 1344, and a switch(es) 1345. The Vin1 and Vin2 1342 is outputted. In an embodiment, the microcontroller MCC 1346 can be connected or associated with, in order to control, the input selector 1341. In an embodiment, the input selector IS can be made using, e.g., solid state relays, and/or electromechanical relays. In FIG. 5E, for example, the system is shown using solid state relays.
FIG. 5F shows an example output selector system. For example, the Vo1 and Vo2 1350 voltages enter an output selector 1351 having switches, in order to put out a Vout1 and Vout2 output voltages 1352. In an embodiment, the microcontroller MCC 1353 can be connected or associated with, in order to control, the output selector 1351.
