Product Description
2 RS232 / RS485 serial relay control board, computer control relay module, communication protocol (at the same time, Modbus RTU protocol and the self-made protocol supports the agreement of two sets, have been posted in the last position of the page).
Test software operation diagram (Ver 1.0.4, for the shop 1 road, 2 Road, 4 road, 8 road series module. Can realize single channel control and combined control test, can modify the software as well as the channel name)
A, function description
RS232/RS485 control relay module, can use the computer through the serial port (serial no turn serial port using USB) connected to the controller to control equipment, interface with switch output, normally open normally closed.
Through automatic control software timing control settings, you can set a few points separately, several, every day or in accordance with the few weeks can also be fixed date and time, similar to the smart phone alarm clock operation. The software can be free to set the road every name, can be user editing time information in form of file processing, is convenient for the user to use.
Even in a multi machine used by the configuration software or automatic control software selection module.
RS232 using public DB9 serial port interface (the straight line, non intersecting line). The power supply adopts standard circular hole in DC5.5 power and wiring terminal power supply, the default Voltage DC12V, meet all kinds of power supply interface, and with reverse connection protection, each output interface are normally open normally closed, controllable voltage AC250V, 10a.
The shell is made of a dedicated rail shell has the advantages of convenient installation, communication protocol using check codes, the controller malfunction caused by interference.
Can network with PLC, configuration software and other products. Home Furnishing, widely used in intelligent lighting control, automatic control, motor control, control, self advertising
Dynamic testing, Hotel hotels, shopping malls workshop, networking, industrial equipment, test equipment, intelligent management and centralized management situation.
Product features
1, communication interface using RS232 and RS485 two kinds of interface can be applied in different communication interface.
2, the power supply interface: using the universal 5.5mm interface and power supply terminals two power supply interface, meet the various needs of interface.
3, output interface: using three port terminals, public, open, closed, more convenient and flexible.
4, internal functions: internal control relay function rich, open communication protocol.
5, all the switches are LED status indication, switch status at a glance (switch state display software), with power indicator.
6, the onboard high crystallinity of real-time clock chip (need custom), power down accurate stability.
Industrial shell 7, configuration standards, standard guide rail mounting groove on the back.
8, the controller can use multiple online, the software can be set.
