The selection of output wiring mode is based on the different output wiring modes of PLC. There are generally two types of output: grouped output and separated output,

Grouped output is a group of several output points that share a common terminal. Each group is separated, and different power supplies can be used separately. Each output point of the separated output has a common terminal, and each output point is isolated from each other. Each output point can use different power supplies. It mainly depends on the power type of the system load. Generally, integrated PLC has both grouped output and separated output.

Selection of output current

The output current (driving capacity) of the output module must be greater than the rated current of the load. The user should select the output current of the module according to the actual load current. If the actual load current is large and the output module cannot be driven directly, the intermediate amplification link can be added.

Number of output points connected at the same time

When selecting the output module, the number of output points that can be connected at the same time should also be considered. At the same time, the cumulative current value of the connected output must be less than the current value allowed by the common terminal. For example, for a 220V/2A 8-point output module, each output point can pass 2A current, but the allowable current of output common terminal is not 16A (8X2), which is usually much smaller than this value. Generally speaking, the number of points connected at the same time should not exceed 60% of the output points of the same common terminal.
