Control command format: Specifications: Model: CE039_12V Product series: RS232 Rated current: 10A Rated voltage: DC12V 3C rated voltage range: below 36V Relay load current: Max 10A Relay load voltage: DC 1-100v or AC85-265v Weight: 67g Size: 8.5 x 4.7 x 1.8cm/3.35 x 1.85 x 0.71inch Package Included: 1 x RS232 Relay 5 control commands: 1. Read status command (used to read the status of the relay (on/off)) 55 56 00 00 00 00 00 AB 2. Relay on (send this command, relay NO and COM will be closed) Relay 1: 55 56 00 00 00 01 01 AD Relay 2: 55 56 00 00 00 02 01 AE Relay 3: 55 56 00 00 00 03 01 AF Relay 4: 55 56 00 00 00 04 01 B0 3. Relay off (send this command, relay NO will be disconnected from COM) Relay 1: 55 56 00 00 00 01 02 AE Relay 2: 55 56 00 00 00 02 02 AF Relay 3: 55 56 00 00 00 03 02 B0 Relay 4: 55 56 00 00 00 04 02 B1 4. The relay is self-locking (relay status is reversed, if the relay NO is engaged with COM, send this command to disconnect NO from COM, and vice versa) Relay 1: 55 56 00 00 00 01 03 AF Relay 2: 55 56 00 00 00 02 03 B0 Relay 3: 55 56 00 00 00 03 03 B1 Relay 4: 55 56 00 00 00 04 03 B2 5. Relay jog (relay NO and COM pull in, disconnect after 200MS) Relay 1: 55 56 00 00 00 01 04 B0 Relay 2: 55 56 00 00 00 02 04 B1 Relay 3: 55 56 00 00 00 03 04 B2 Relay 4: 55 56 00 00 00 04 04 B3 6. Relay interlock (corresponding relay is closed, other relays are disconnected) Relay 1: 55 56 00 00 00 01 05 B1 Relay 2: 55 56 00 00 00 02 05 B2 Relay 3: 55 56 00 00 00 03 05 B3 Relay 4: 55 56 00 00 00 04 05 B4 Every time a command is sent, there is a return frame, and the 7th byte in the return frame contains the status of the relay. Return to instruction: 2 return instructions 1. Return to relay on (return to this command, indicating that the relay NO and COM are in the pull-in state) Relay 1: 33 3C 00 00 00 01 01 71 Relay 2: 33 3C 00 00 00 02 01 72 Relay 3: 33 3C 00 00 00 03 01 73 Relay 4: 33 3C 00 00 00 04 01 74 2. Return to relay off (return to this command, indicating that the relay NO and COM are disconnected) Relay 1: 33 3C 00 00 00 01 02 72 Relay 2: 33 3C 00 00 00 02 02 73 Relay 3: 33 3C 00 00 00 03 02 74 Relay 4: 33 3C 00 00 00 04 02 75
