4.2 HSA modules
Every output of the module can be measured by the internal ADC. It is possible to
measure the voltages and the total current from every module without a load. The
ADC resolution is 12 Bit . The configuration for HSA modules is shown in following
tables.
Tips:
● The RelayOut Bits have to be 1 so that the relay is closed and 0 for it to be
open.
● Fast/Slow Bits are so encoded that 1 sets fast mode and 0 sets slow mode.
Usually one wants to use the fast mode.
● For increased readability empty values in the operation mode tables denote
binary 0.
● Bits which value do not matter are denoted by “x”.
