the terminal is ON and is inactive (state "0") when the terminal is OFF.
The 250 VAC reinforced insulation must be satisfied between the relay outputs and the
logic circuit of the PLC. In addition, the 250 VAC reinforced insulation must be satisfied
between the output terminals of different common terminals.

Output common terminal
Each group shares a common terminal COM. The groups are
insulated.
Fuse protection -
When some or all transistors in each group are with load, the average current for each channel must not
exceed 0.2 A. The maximum current for a single channel must not exceed 0.5 A.
Internal Equivalent Circuit
The following figure shows the internal equivalent circuit of relay output. Output terminals
are divided into several groups, with each group electrically isolated. The output contacts
of different groups are connected to different power circuits.
