Optocouplers electrically isolate the digital outputs from the OP.
The components to be driven (e.g. relays, signaling indicators, etc.) are con-
nected by means of the five-pin connectors supplied:
Connect the wires
(conductor cross-sections 0.5 to 2.5 mm
2
)
Seat the terminal blocks on the pins of the DKM
The DIL switch setting determines how the digital outputs of the DKM are
controlled:
in the OFF position, by pressing function keys
in the ON position, by software
Software can control up to 16 DKM outputs, whereas only twelve can be con-
trolled by function keys.
Setting the DIL switch:
DKM A
DKM B
S1
S2
S3
S4
OFF
ON
S1 must always be set to ON
S2 selects the module board (DKM A
or DKM B)
S3 and S4 both act on one group of
outputs (refer to table)
