Note: SYAD08 series modules support both RS232 and RS485 communication interface. User can choose the communication interface according to the application environment, and at the same time only one interface works, otherwise it may interference with each other.
E. G.: SY AD08A4 Means 8-channel 4-20mA signal input, RS232/RS485 output
SY AD08A7 Means 8-channel 0-± 20mA signal input, RS232/RS485 output
SY AD08U1 Means 8-channel 0-5V signal input, RS232/RS485 output
