5.3. Digital inputs.
Parameter, characteristics Value, description
Total number of digital inputs (DI1-DI16, DI_SYN1, DI_SYN2)
Of these, the number of digital inputs with synchronization function
(DI_SYN1, DI_SYN2) 18
2
Data entry modes Asynchronous
Synchronous streaming,
synchronous self-oscillator.
Program control of pull-up resistors activation:
- for inputs DI1-DI16 No pull-up resistors (unlike
L-502)
- for inputs DI_SYN1, DI_SYN2 Regardless of each input
Maximum speed in synchronous mode 2 Mwords/s
Maximum speed in asynchronous mode. The actual speed depends on
many factors of the software
and hardware environment.
Recommended operating voltage range 0 …+5.5 V
Operating voltage range
-0.2...+0.6 V ("logical zero")
+2.4...+5.0 V ("logical
item").
High-impedance state with power off Yes
Maximum input current with power off 10 µA
Own input current in operating mode with software-activated pull-up
resistors 10 µA
Recommended edge duration:
- at the input DI1-DI16
- DI_SYN1, DI_SYN2
0…50 ns
Not limited
The input hysteresis voltage DI_SYN1, DI_SYN2, typical value 400 mV
