Power supply and DB port power supply settings:

This product is designed for redundant power supply and has power loss alarm output

Each DB port contains a 4-core power cord for supplying power to the PLC module. These power supplies are controlled by the short circuit cap set by the power output. Each short circuit cap corresponds to a wire, as shown in the figure above on the right. Before power transmission, it should be set as required.
