Reading status(reading the satus of the relay (on/off)) 0x55 0x56 0x00 0x00 0x00 0x00 0x00 0xAB2.Relay open (issue this command,Relay open,COM connect to NO) Channel 1 : 0x55 0x56 0x00 0x00 0x00 0x01 0x01 0xADChannel 2 : 0x55 0x56 0x00 0x00 0x00 0x02 0x01 0xAE3. Relay close (issue this command,Relay close,COM disconnect NO,and COM connect to NC) Channel 1 : 0x55 0x56 0x00 0x00 0x00 0x01 0x02 0xAEChannel 2 : 0x55 0x56 0x00 0x00 0x00 0x02 0x02 0xAF4. Relay toggle(Relay status reversal,if COM connect to NO,this commands will Disconnect COM to NO and Reverse COM connect to NC,and vice versa) Channel 1 : 0x55 0x56 0x00 0x00 0x00 0x01 0x03 0xAFChannel 2 : 0x55 0x56 0x00 0x00 0x00 0x02 0x03 0xB05. Relay momentary(Relay COM connect to NO,disconnect after 200MS) Channel 1 : 0x55 0x56 0x00 0x00 0x00 0x01 0x04 0xB0Channel 2 : 0x55 0x56 0x00 0x00 0x00 0x02 0x04 0xB1Once issue a command,will have a return fame,7th byte of return fame mean the satus of realy.2 return command 1.Return relay open(return this command,mean COM connect to NO) Channel 1 : 0x33 0x3C 0x00 0x00 0x00 0x01 0x01 0x71Channel 2 : 0x33 0x3C 0x00 0x00 0x00 0x02 0x01 0x722.Return relay close(return this command,mean COM disconnect NO , and COM connect to NC) Channel 1 : 0x33 0x3C 0x00 0x00 0x00 0x01 0x02 0x72Channel 2 : 0x33 0x3C 0x00 0x00 0x00 0x02 0x02 0x73Instruction manual Please ask us after the purchaseApplication Remote control, remote measurement system; Wireless meter;Smart Home,Home Automation ,Wiser Home;Access control ;Identification system;Data collection; IT household appliance;As a PLC expansion boardIntelligence household appliance;Baby monitoring system;Typial application : DC 1-110V OR AC 85-265V control circuit,Wiring diagram below(Note:If not DC 12V load, need another DC 12V power supply).
