Digital Input Interfaces – TTL Mode
Feature
Details
Suffix applicable
T or 1
Type of input
Optically isolated
Input current
for all inputs
Iin = 3.8 mA @ Vin = 5 V
High-level input voltage
2.4 V < Vin < 15 V, 5 V typical
Low-level input voltage
0 V < Vin < 0.8 V
Minimum pulse width
>250 µsec for inputs 1-6, >3 msec for STO
Execution time (all inputs):
the time from application of
voltage on input until execution is
complete
0 < T < 250 µsec
High-speed inputs – 1 to 6
minimum pulse width, in high-
speed mode
T > 5 µsec if the input functionality is set to
latch/capture (index/strobe).
Notes:
• Home mode is high-speed mode and can be used
for fast capture and precise homing.
• Highest speed is achieved when turning on
optocouplers.

Capture with differential input
Port A, Port B Index
T > 0.1 µsec if the differential input functionality is set
to touch probe/capture (index/strobe).
