The digital inputs and outputs are built as two eight-pin sockets in A-coding with M12 threads. The inputs are
double insulated from the power supply of the reader and can be operated irrespective of the polarity of the
input signal. For this reason there is a common pin for the inputs (INP_CMN). The connection variants for the
inputs are shown below.
Note: Please note that the load per channel is limited to a maximum of 0.5 A, and the total load across all the
channels must not exceed 1.5 A. The inputs and outputs are designed for a maximum voltage of 30 V DC.
Further information can be found in the data sheet for the reader.
