All unused digital inputs should be grounded. The digital Outputs are open collector
outputs and are capable of driving 20mA in a Low State.
II
Warning
DO NOT exceed 5.1V or fall below 0V on the I/O ports of the PC 62C.
Permanent damage will result if these thresholds are exceeded.
2.5) Power supply connections
The +12V and +5V power and digital ground are available on the DB37 Male Connector
(P1). These are equipped with Polyswitches that will open circuit if the max permissible
current of 250mA is exceeded. Connections to the power lines will be restored if the
current falls below the max permissible current draw.
II
Warning
The maximum permissible current draw on the +5V and the +12V lines on the
I/O connector is 250mA.
