3.1.4
Analog value representation for analog output channels
The table contains the analog value representation of the SM 335’s output chan-
nels.
12 bits (+VZ) of the output value are converted in the 0-10 Volt range.
Bit 0, Bit 1 and Bit 2 are not converted.
11 bits + VZ of the output value are converted in the + 10 Volt range.
Bit 0, Bit 1, Bit 2 and Bit 3 are not converted.
