2 Channel Support Modbus TCP Protocol Dc 5V Relay Module, 3.2 X 2 X 1.2Inch Network Relay, TCP Client and Udp Mode for Smart Home MultiClient Use

Specification: Item Type: IP Network Relay Module Supply Voltage: 5V Current: Not less than 1A Two-channel relays can reach a single function rate of 2KW, AC load rated voltage 250V, current 10A, DC load rated voltage 30V, current 5A Size: Approx. x 50 x 31mm / 3.2 x 2 x 1.2in Operating Temperature: -40℃ to 80℃. Applications: 1. Can be used for power failure detection in the computer room, can be connected to human body infrared sensors, can be connected to key switches, can be connected to smoke alarm output. 2. Can be connected to smoke alarm output, can be connected to human body infrared output 3. Can be connected to key switch, can be connected to any passive switching input, can also be connected to active switching input (connected to 5V active switching). 4. Can be controlled by external network, and can be controlled remotely by mobile phone. Control Instruction: Send: turns on the first relay Send: off1 turns off the first relay; the second control method is the same. Send: read1 means to read the state of the first relay. If it returns , it means that the first relay is on, and off1 means that the first relay is off. Delay control, such as Send: : 02 Means That The Relay Will Open After 2 Seconds, and send on: 12 means that the relay will open after 12 seconds. The maximum delay is 99 seconds. For MODBUS 1.01 This code is to read the state of the relay. The relay address is 0010 on the first channel and 0011 on the second channel. 2.05 This code is to control a single relay. The relay address is 0010 on the first channel and 0011 on the second channel. 3. 0F This Code Is To Control Two Relays. The Relay Addresses are: No. 0010, No. 0011.
