The LK-RM304 is an RS485 board with four high-power relay outputs and six digital inputs. Modbus control software, an HMI, a PLC or similar equipment can switch the relays and read back both the relay states and the digital inputs. It supports 315 MHz / 433 MHz remote controls, and the enclosed version can also be operated from local push-buttons. Suitable for IoT and automation control applications.
