4) Maximum Load Currents for 12/24-VDC 32-point Output Module
Although a 0.3-A load can be connected to each output point of the DC 32-point
Output Module, the total load must be 0.4 A or less for each of the four output points in
the same area marked by the shaded portion in the following figure. Keep the load
distribution within the 0.4-A limit.
If this limit is exceeded, damage may occur to the output circuit.

5) Loads with Large Inrush Current
Connecting a load with a large inrush current, such as incandescent light bulbs,
may cause dark current flow of up to 30
% of the rated current of the incandescent
bulb. Here install a current limiting resistor in series with the load. Be sure to use
this or other methods to keep the inrush current below the maximum load current of
the Output Module.
If the load current exceeds the maximum load current, the output circuit will be dam-
aged.
