This chapter gives a short description of the extension module.
Product overview
The FDIO-01 digital I/O extension module expands the digital
inputs and outputs of the drive control unit. It has three digital
inputs and two relay outputs.
Compared to the FIO-01 digital I/O extension module, FDIO-01
has a wider input voltage range and basic insulation between all
inputs, outputs, and the drive control unit interface. If you connect
one or more inputs/outputs to the AC power line, you can still
safely connect the other inputs/outputs and the drive control unit
inputs/outputs to SELV or PELV circuits.
The extension module makes the signal and power connection to
the drive through a 20-pin connector.
