4.1.2 Analogue Outputs (DAC)
The S600+ supports four analogue outputs (D/A Converter). Each
D/A Converter channel is fully floating and provides its own floating
supply. Loads of up to a 650-ohm loop impedance can be connected
directly. The unit can be used in either source or sink configuration.
Refer to Figures 4-6, 4-7, and 4-8.
The D/A Converter output channels use the connector labeled SKT-A,
which is located on the backplate of the I/O module. Refer to Table 4-3
for the D/A Converter output pin connections on the back of the I/O
module.
