Power supply and DB port power settings:

This product is designed for redundant power supply and comes with a power loss alarm output

The DB port contains a 4-core power cord for supplying power to the PLC module. These power supplies are controlled by short-circuit caps set by the power output, with each short-circuit cap corresponding to a wire, as shown in the upper right figure. Before power transmission, settings should be made as needed.

Special note:

1. The brightness of the circuit LED can roughly indicate the magnitude of the circuit current;

2. Using a multimeter to short-circuit the current range of this circuit test hole can accurately measure the inner current without affecting the circuit operation;

When the circuit LED fails and opens, a spare LED can be inserted into the test hole for repair;
