Wiring of Outputs
In case of base units with only few outputs (e. g. FX
be connected separately. In case of the base units with more outputs, the outputs are pooled into
groups of 2, 3, 4, 8 or 16 outputs. Each group has a common contact for the load voltage. These
terminals are marked "COM„" for base units with relays outputs or transistor outputs of the sink
type and "+V " for base units with source transistor outputs. " " stands for the number of the
output group e. g. "COM1".
Because the outputs groups are isolated against each other, one base unit can switch several
voltages with different potentials. base units with relay outputs can even switch AC and DC
voltages.
The first group of outputs is used to switch a DC voltage.
The second group of relays controls AC powered loads.
The selection of sink and source output type is done by the selection of a correspondent base
unit. Both types are available with DC or AC power supply. The output type is given in the model
designation code: base units with the code "MT/ S" provide transistor sink type outputs (e. g.
FX
-16MT/ES) while base units with the code "MT/ SS" provide transistor source type out-
