5.5. I/Os
The Gold Whistle has:
• 6 Digital Inputs
• 2 Digital Outputs
• 1 Analog Input
5.5.1. Digital Input Interfaces – TTL Mode
Feature Details
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
Execution time (all inputs):
the time from application of
voltage on input until execution is
complete 0 < T < 250 µsec
High-speed inputs – 1–6 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.

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