Product Description
The four-bit solid state relay board is also known as the four-channel solid-state relay board.
Main Functions:
1.Provide optoelectronic isolation between the PLC control circuit and the control contactor circuit to ensure that they do not interfere with each other and also ensure the safety of the control system.
2.Directly introduce the -14VDC generated by the DC control module into the control circuit. This reduces the load on the DC control module power supply and ensures the power requirements when the contactor is closed/opened. It also reduces the failure rate of the control circuit.
