Item specifics
  • Test1: 4
  • Test4: 4
  • is_customized: Yes
  • Model Number: 2 way Ethernet relay
Product Description
Power requirements: Micro, USB DC5V power supply; or DC9-24V
PCB size: long X 70mm wide 50mm
Function description:
Control 2 relay through the Ethernet network pick-up release pin is 6 digital input, the state can query through the network. Module supports both TCP and UDP2 modes of operation, the instructions are simple and easy to understand, the instructions can be specified in the 1 - 65535 seconds delay. Module with VB, Delphi PC program and source code, to help you easily achieve computer remote control. TCP mode under the host computer can check the status of all relays, and in addition to the completion of each instruction, the module will return to the latest status of all relays. There is no state query or other return in UDP mode, the code is very simple, easy to embed into a variety of applications.
Module features:
Industrial grade STC microcontroller control chip
Board 2 high quality relay, relay with absorption diode circuit
With 1 power indicator, each relay status indicator lamp, lamp relay
With 6 digital input, pin connection state can query through the network
You can configure the module parameters, such as the module IP address, the default gateway, and so on.
Relay status before power down (configurable)
Support 5V or 9-24V input voltage
1.6mm thick FR-4 by the military level PCB board, PCB size X 50mm 70mm, set aside for the installation hole
Operation method:
Module factory set to:
IP address network parameters can be configured through the network
Default gateway
Subnet mask
TCP port 6722 module service port can not be configured
UDP port 6723
Configuration module parameters can be configured through the network, the configuration interface is as follows. The network parameters due to incorrect configuration tool to connect module, short circuit and CLR jumper give power to the module can restore factory default settings.
Command code for text string, do not need to follow the carriage return.
Get relay status 00 (UDP does not support)
CH1 is 11
CH1 release 21
CH2 is 12
CH2 release 22
TCP mode, each time the module receives the command byte, will return to the latest status of the relay. The text of the return value is a 8 character string, each character is either 0 or 1, on behalf of the relay and the digital input of each channel, such as the return value of 11000000 indicates that CH1 and CH2 can be digital input for low level.
Interface description:
+5V +5V: power positive, input or output
GND: power supply, input or output
P30 - P35: 6 digital input
CLR: short connected to CLR and to the module on the power to restore the factory settings
Blue terminal: the user load, you can use the 220V AC equipment, or less than 30V of DC equipment, the equipment can not exceed the current standard relay load. Each relay has one normally open contact and a normally closed contact and a public contact relay, public contact and the normally open contact conduction; relay release, public contact and the normally closed contact conduction.
Module structure diagram:
Network real time control software interface:
Software settings are simple to support the use of dynamic domain name
Can show or hide the expansion channel
6 client programs can be run simultaneously on different computers to control the same module.
Mobile terminal control software interface (only support Android), Basic4android language development to provide all the source code:
PC program introduction:
Support UDP2, TCP connection mode
Complete instruction sheet
Delay parameters can be set
Displays the data sent and received by the network
With Delphi, VB source code
