O UTPUT W IRING E XAMPLES
Any external circuit or device to be connected to the ClearPath output
should conform to the guidelines below. Proper circuit design/selection
greatly reduces the probability of electrically damaging the output,
particularly in the event of a common production mistake such as an
accidental short or reversed wiring.
S INKING O UTPUTS
Outputs can be used as a sinking output as shown below. This topology
provides ClearPath with a high level of immunity from damage if, for
example, the circuit is shorted to machine chassis. Such a short would
simply make the output appear like a closed circuit.
