Figure 4 Input signal single-ended common cathode connection
Note: The voltage range of the signal input interface in the figure is 4.5 ~ 28Vdc. No
matter whether it is single-ended connection or differential connection, no series
current limiting resistor is required. For the external pull-up voltage of the output
interface, the maximum is 28Vdc, and the maximum output current is 100mA. According to
the external pull-up voltage, select the appropriate pull-up resistor. If the external
pull-up voltage is 24Vdc, the pull-up resistor is 2K. If The external pull-up voltage
is 12Vdc, and the pull-up resistor is 1K. If it is a drive relay or motor holding brake
coil, please consult our application engineers.

In order to avoid some misoperations and deviations, PUL-, DIR- and ENA- should meet
certain requirements, as shown in the following figure:
