Two backplane voltage options are available: 5V to 12V and 5V Only. The 5V to 12V option is usable for backplanes of 5V or 12V (or anything in between). The 5V Only option is usable only for 5V backplanes. The 5V Only option is suggested because this option is frequently less expensive than the 5V to 12V option. Analog or Digital modules are available only with 5V to 12V backplane option.

The suggested component part numbers also list the rated output current and current sharing capability.
