Input Connections

Current on these inputs must be limited to 20 mA

or less, through the use of a current-limiting resistor. An
external power source (24 volts DC maximum) is rec-
ommended for all inputs and outputs, to prevent ground
loops between equipment.

However, if customer equipment is completely iso-

lated, using power from the GPIO port connectors is
acceptable. Figure B-4 shows details for both types of
connections:
