Unitronics
•
When used as a normal digital input, normal input specifications apply.
5.
Only in JZ20-J-T20HS:
•
I0, I1, and I4 can function as high-speed counters, as part of a shaft-encoder, or as
normal digital inputs.
•
I2, I3, and I5 can function as either counter reset, as part of a shaft-encoder, or as
normal digital inputs.
•
If I0, I1, I4 are set as high-speed counters (without reset), I2, I3, I5 can function as
normal digital inputs.
•
When used as a normal digital input, normal input specifications apply.
