Detailed description of the connections
Described in detail in the following are the individual connections and pin assignments.
7.4.1 PWR / SW IN/OUT - Voltage supply and switching input/output 1 and 2
Supply voltage
The bar code readers of the
BCL 300
i
… series are designed in accordance with protection class III for
supply by PELV (protective extra-low voltage with reliable disconnection).
Connecting the functional earth FE
Ensure that the functional earth (FE) is connected correctly. Unimpaired operation is only guaranteed
when the functional earth is connected properly. All electrical disturbances (EMC couplings) are dis
-
charged via the functional earth connection.
Switching input/output
The bar code readers of the BCL 300
i
series are equipped with two freely programmable, opto-decoupled
switching inputs and outputs, SWIO_1 and SWIO_2.
The switching inputs can be used to activate various internal functions of the BCL 300
i
\ BCL 301
i
(decoding, autoConfig, …). The switching outputs can be used to signal the state of the BCL 300
i
\
BCL 301
i
and to implement external functions independent of the superior control.
Described in the following is the external wiring for use as a switching input or output; the respective func
-
tion assignments to the switching inputs/outputs can be found in Chapter 10.
