The Isolated Digital I/O Module adds an additional six 5 to 24 VDC isolated I/O channels. All of the I/O channels can be individually programmed as either inputs or outputs, or as dedicated (limit, home, etc.) or general purpose.
When used as inputs, these I/O channels have seven programmable digital filter settings ranging from 215 Hz to 27.5 kHz. As outputs, each channel can sink up to 350 mA. The I/O is isolated from the power supply ground.
A 7.5kW switch selectable pull-up resistor is provided for each I/O channel. The six I/O channels may be pulled up to either the internal +5 VDC supply or an external voltage provided by the user. Protection circuitry includes over temperature, short circuit and inductive current clamp.
