Optocoupler adapter OKA-4

1x optocoupler adapter OKA-4 To control sounds and functions via switch inputs. 4 inputs and outputs (potential-free).

With the help of the optocoupler adapter OKA-4 can at the sound module USM series, the additional sounds / functions via the switching inputs are triggered.
On the OKA-4 4 are isolated inputs and outputs. The output of the OKA-4 switches on the sound module, a sound or a a function that when a voltage of about 2,0 on the associated input - 15,0V applied. it does not need to be paid to the polarity of the input voltage. Therefore, the OKA-4 for example, can be directly connected in parallel to a motor to always trigger an additional sound when the engine is running - no matter in which direction.
The 4 outputs can be selected as plus or minus switching outputs, thus the OKA-4 can be used for all Beier sound modules.
The connection of the inputs and outputs are with solder connections.Technical data
