Modbus-RTU 12V 8 Channel Relay Module
Modbus RTU/RS485 8 Channel 12V Relay Card is used to control devices via Modbus RTU or RS485 . This is a single-channel Modbus RTU relay module equipped with stable 8-bit MCU and RS485 level communication chip, adopting standard MODBUS RTU format RS485 communication protocol. It can realize 2-bit input signal detection and provide 2-bit relay output. Can be used for digital sensing or power control situations.
