The module is equipped with four 10A / 250VAC relays controlled independently via a serial bus (UART) or from a PC (through a microUSB connector). The NO / NC contacts of the relays have been led to the ARK screw terminals. The board recommended for use with Arduino enables control of four relays using only two microcontroller lines.
The card does not work with Microsoft Windows 8, 8.1, 10 operating systems
The modRL04_uUSB module is controlled via the UART bus. When the power is turned on, the relay card is waiting for the hexadecimal value 0x50. If it is sent to the module, it will reply with its identifier (ICSE012A has the identifier 0xAB). After this operation, sending the number 0x51 will enter the module into the bus listening state - each subsequent received value will control the relays. For the value 0x00 all relays are on, and the value 0xFF disables all relays. For example, the value 0x07 (binary: 0111) will turn on the first relay, excluding the others.
