Pin assignment Note: For digital inputs 1 to 6, the switch-on threshold is 1.86 V, the switch-off threshold is 0.91 V DC. The maximum sampling frequency is 1 MHz. If the I/O pins are used as output (see Defining input and output assignments), the maximum admissible current is approx. 10 mA at 3.3 V DC. The range of the analog inputs is 0 … 3.3 V DC. The encoder signal is single-ended, the switch-on threshold is 1.86 V, the switch-off threshold is 0.91 V DC. The maximum sampling frequency is 1 MHz. The current consumption of the UB_LOGIC logic supply is approx. 30 mA at 24 V DC.
