Hardware Expansions Electrically Isolated Analog In the case of potential differences between the nega-tive load input Interface the standard Analog I/O card can be replaced with an isolated version. All measurement and control signals are trans- mitted via isolation amplifiers and compatible with the standard Analog I/O card. The isolation voltage is 500 V DC with respect to the negative load input. screwed onto large devices for easier transport. A 19" rack can then often be dispensed with. This option is available for de- vices from 5HU and is suitable only for hard floors. Factory Calibration...
