1 control circuit interface

Output part: relay: NC (Changzuan) COM (Public Foot) N0 (Changkou) relay connected load: Maximum parameter 220V 10A is recommended to be below 220V 6A.The relay is just the turnover and disconnection of a switch without any voltage output.It can only control the opening and shutdown of relays through 485 communication instructions.Enter part: IN connection or voltage signal (3V -30V) function

Function 1: Set the device address

Function 2: Read the device address

Function three: Read all in input status (can only be used for the address, you cannot read it in a broadcasting manner)

Function 4: Read all relays to close state (can only be used for the address, you cannot read it in a broadcasting manner)

Function 5: Read the equipment software and hardware version number

Function 6: Relay operation is turned off and the LED switch

Function 7: All relays are turned off and closed

Function 8: relay and input IN association operation

(Related relationship is corresponding, No. 0 relay -in1, 1 relay -in2, ...)
