MRFT1S Series Relay Module
Features
It is used for PLC output load current amplification and isolation protection. It is installed in the digital output terminal of PLC, MCU industrial control board, time relay, button and other controllers. It amplifies the output current of the output terminal for high-power equipment and weak current control. In such occasions, to protect the control system core is not destroyed.
