The digital output and analog input pins on the head I/O are configured
differently from the pins on the base I/O.
The two digital output pins can source 100 mA of current each, while the single
24 V power pin on the tool port can source a maximum of 1 A. This is shared with
the digital outputs and so there may be less than 1 A available at the 24 V pin
depending on your configuration.
Digital outputs are protected from over-current damage with a Positive
Temperature Coefficient (PTC) resistor. If an overcurrent event occurs you may
need to wait for the PTC to cool for 10 minutes before outputs can be used again.
The two analog input pins can only measure in voltage mode. They are
configured as follows:
