Features: _x000D_ This 8-way 10A relay controller has normally open and normally closed output. _x000D_ 8-way switch on-off input. _x000D_ Can be used for smart home control, secondary development of mobile phone or computer remote control lights, motors, and other electrical equipment. _x000D_ Can be used for computer room power failure detection, can be connected to human body infrared sensor, button switch and smoke alarm output. _x000D_ C++ source code is provided. _x000D_ Reliable network connection, network will automatically reconnect if it is off-line. _x000D_ In TCP service mode, it can support 4 network connection, using 32-bit MCU. _x000D_ Very convenient network parameter setting software._x000D_ _x000D_ Support working in TCP server, TCP client, and UDP mode._x000D_ _x000D_ Support 4 client connection when working in TCP server mode._x000D_ _x000D_ Supports user-defined name, no need to record IP number when there are many equipment._x000D_ _x000D_ Supports user-defined heartbeats packet time, reliable off-line network restore. _x000D_ _x000D_ Can work in switch on-off unvarnished transmission mode._x000D_ _x000D_ Download three firmware through configuration project, respectively are general firmware, switch on-off unvarnished transmission firmware, access control firmware. General firmware is working in slave mode, using command to control. Switch on-off unvarnished transmission firmware is used in pairs, one input control the other output, each input correspondingly controls other relay output. Access control firmware can connect to four 26 protocol read heads. _x000D_ _x000D_ _x000D_ Specifications:_x000D_ Power Supply: DC 9-24V, 2A_x000D_ Output: 8-way relay output, each way has max. power 2kW, max. current 10A, max. voltage 250V (AC or DC), no voltage output, output is relay switch on-off._x000D_ Input: Can input switch on-off, passive or active, maximum active is 5V. _x000D_ Material Download: _x000D_ http://pan.baidu.com/s/1i34g9wD (password: qr9e) _x000D_ _x000D_ _x000D_ Network Parameters: _x000D_ Support to control across gateway (need to set router retransmission), remote control need to solve the problem of dynamic IP by yourself(public IP is not the same every time router starts up)_x000D_ TCP Support Command: 01 reads relay status, 05 operates single relay, 0f operates all relays, 02 read switch on-off input._x000D_ Product Control Command:_x000D_ Send on1 will open the first way relay,_x000D_ Send off1 will close the first way relay, 2-8 way control method is the same._x000D_ Send read will read relay state, if return to relay00000001, it means the first way relay is energized, 2-8 way relays are dis-energized._x000D_ Support time delay control, for example, _x000D_ Send:on1:02, means relay is energized for 2 seconds then dis-energized_x000D_ Send:on: 12 means relay is energized for 12 seconds then dis-energized, the longest delay time is 99 seconds._x000D_ Application:_x000D_ 1. Can be used in smart home control._x000D_ 2. Can be used for secondary development of mobile phone or computer remote control lights, motors, and other electrical equipment._x000D_ 3. Can be used in computer room power failure detection, can be connected to human body infrared sensor, button switch and smoke alarm output._x000D_ 4. Can be used for access control system, control computer to turn on, and remote control electric appliance._x000D_ 5. Can smoke alarm output, can meet the human body infrared detector output,_x000D_ 6. Can pick button switch, can pick up any passive switch input, and can also meet the active switch input (connect 5 v active switch amount)._x000D_ 7. Can control by external network, mobile phone remote control (mobile phone APP should developed by yourself). _x000D_ _x000D_ _x000D_ Package Includes: _x000D_ 1 x Relay Controller
