Special Considerations for C500-OA225

The maximum current value allowed per output point depends on the ambient temperature and the number of

points per common that are ON simultaneously. The graph below shows the relationship between the allowable

current per point and the number of points ON per common. Be sure not to exceed the values shown in the graph.

The graph below shows the value of the surge current and the time it takes the current to reach a steady state

(current-carrying time). The curved line in the graph represents the maximum value of surge current at which the

Unit can operate properly. It is suggested that when opening and closing a load with a large surge current, to keep

the value of the surge current to half the value shown the graph (within the shaded area).
