Installation and Configuration
2.7. Digital Inputs (TB101 B)
The digital inputs are opto-isolated and may be connected to current sourcing or current sinking devices, as
shown in
Figure 2-12
and
circuits and are not intended for high-voltage isolation.
Inputs 0-3 and inputs 4-7 have separate common inputs (refer to
be connected in the same configuration (sinking or sourcing). Bank 1 can be connected differently from Bank
2, however.
The opto-isolator's common connections can be directly connected to the drive's power supply; however,
doing so will effectively defeat the isolation and will reduce noise immunity.
