Can I Cascade the Voltage Outputs of an SCXI-1124?Hardware: SCXI>>Modules>>SCXI-1124
Problem: I would like to output a voltage higher than 10 V from an SCXI-1124. I know that each channel is isolated and referenced to its GND pin. Can I cascade these outputs to output a larger voltage? Solution: Yes, you can cascade the voltage channels of the SCXI-1124. You can wire the VOUT terminal of one channel, say Channel 0, to the GND pin of another channel, say Channel 1. The voltage output from Channel 0 becomes the reference of Channel 1, and any voltage output on Channel 1 will be referenced from this voltage. Therefore, you can achieve greater than 10 V of output by measuring between the GND pin on Channel 0 and the VOUT pin of Channel 1. For instance, if you wired the VOUT terminal of Channel 0 to the GND terminal of Channel 1, you could output 19 V with an SCXI-1124 by outputting 10 V on Channel 0 and 9 V on Channel 1. Note: You can expand this method to cascade multiple channels on the same and different modules. However, you must remember that on the SCXI-1124 any isolated voltage ground cannot have more than 250 Vrms of common-mode voltage between itself and any other channel or chassis ground.
