Installation and Configuration
2.7.1. Digital Outputs (TB102 A)
The digital outputs are optically-isolated and can be connected in sourcing or sinking configurations. The
digital outputs are designed to connect to other ground referenced circuits and are not intended to provide
high-voltage isolation.
Outputs must be connected in either all sinking or all sourcing mode.
how to connect to an output in current sinking and current sourcing mode, respectively.
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.
N O T E : The outputs are protected by resettable thermal fuses. If there is an overload, removing the
overload will reset the fuse.

Suppression diodes must be installed on outputs driving relays or other inductive devices. This protects the
outputs from damage caused by inductive spikes. Suppressor diodes, such as the 1N914, can be installed
on all outputs to provide protection. It is important that the diode be installed correctly (normally reversed
biased). Refer to
