LAN Ethernet 2 channel Relay Board Delay Switch TCP/UDP Controller Module WEB Server
Note: This product does not come with a case and has normally open and normally closed contacts
1. Industrial-grade STC microcontroller +ENC28J60+ stable firmware supports 6 network connections in TCP server mode, and also provides UDP control mode to achieve cloud remote control function
2, the control instructions are very simple, string mode send 11 open the first relay, send 21 close the first relay, 11* command the first relay click, 11K command simulate the first local button (only for the local button model), 11:10 open the first 10 seconds automatically closed (delay support 1-65535 seconds); Send 00 to return all channel status
3, fully support secondary development, local connection, cloud remote control, PC and mobile phone have demonstration programs and source code, provide module configuration program, timing program DLL packaging, easy to integrate various configuration functions
4, the hardware is extensible, the pin on the module can be connected to real clock, 485, Bluetooth, 2.4G...
5, 8-bit reduced instruction system has powerful functions, low development cost, and functional customization has a price advantage
Power supply method: 3 No. 5 batteries
The USB port is used to obtain power
Mobile phone charger
Mobile power supply
PCB size: 70mm long X 50mm wide
Fully support secondary development, open TCP, UDP control protocols, cloud remote secondary development kit provides SOAP Web Service API interface and RESTful Web Service API interface.
*industrial STC single chip microcomputer as the main control chip
* Onboard 2 high quality relays with absorbent diode circuit
*There is one power indicator, and each relay has a status indicator. If the indicator is on, the relay is plugged in
*6 TTL outputs, and the relay module can be extended to reach 8 outputs. Note: The relay module should be active at high level
* You can configure module parameters, such as the module IP address and default gateway, over the network
* Maintain relay status before power failure (configurable)
*Controlled through the internet, cloud remote control is protected by local password, safe and reliable
* Automatically synchronizes network time (NTP). You can set 32 timing points. The error of the timer is less than 1 second
*Flexible timing Settings can be executed once, or on an annual, monthly, daily, weekly, hourly, minute-per-second cycle
*Supports Modbus TCP
* Support 5-24V input voltage, choose one of two power terminals
*1.6mm thick PCB made of military grade FR-4 plate, PCB size 70mm X 50mm, reserved mounting holes
