Figure 6 – Connector «ХР1»
When jumper is set to position «CH1», input «CH1» is activated forcefully, au-
tomatic switchover to «CH2» does not occur. When jumper is set to position «CH2»,
input «CH2» is activated forcefully, automatic switchover to «CH1» does not occur.
2.3.2.4 Remote select of active channel is a type of manual channel select. To
select this mode, the PCB has a terminal block with three outputs «SELECT», see Fig-
ure 7.
Figure 7 – Terminal block «SELECT»
Three-core cable is connected to this terminal block; closing remote cable out-
puts (for example, using switch), users may select active channel. To select «CH1»,
close «1» and «2», to select «CH2» – outputs
«2» and «3».
2.3.3 Independent operation mode
Independent operation mode is used for multiplication of data received via two
input channels at the same time. Therefore, the Product has two groups of input chan-
nels – group A and group B. Each group has two non-isolated outputs and two optoiso-
lated outputs, see Figure 8.
