Relay Controller with 4 Channel Output

JMDM-COM4DOMR Serial Port Control 4-Channel Relay Controller
Product introduction
JMDM-COM4DOMR is a high reliability and stability industrial PC digital serial port controller which independently research and development by Shenzhen jingmin digital machine Co., Ltd...Can be used to the switch control of 4-channel 10A large load, the high-power devices such as lighting, heating wire, power switch, and strong-power switch. There are two kinds of working methods: Independent control and serial port control. The former is the controller realized automatic independent control according to the PC program; And the latter is through computer equipment to do the PC, online by serial port sending instructions communicate with computer to realize real-time monitoring output.
Technical parameters and characteristics
1) the controller comes with the rectifier circuit, the input regardless of the positive and negative, so the AC and DC power supply universal.
2) Two DIP switches: Programming can be used as two input point to set special function, if it is can set 4 kinds of input status. Haven't set any functions In the Jingmin sample serial monitoring software.
3) The working status indication of the controller: Two LED light to display power and operating status.
4)4-channel relay output: Optically isolated relay output, passive dry contact form, you can directly control the maximum AC 220V voltage and DC 30V voltage; Each maximum output current is 10A, the output state can be read back, back to read the agreement below; Back to read agreement as below;
5)4-channel relay output is divided into two groups, wiring respectively, each group can be used to control different loads such as contactors, a variety of lamps, electric wire, electric motors and a variety of electrical loads;
6) Communication Interface: 1 standard RS232 serial communication interface (anti-15KV electrostatic shock), can communicate with computers and the other PC; Directly download the program by the RS232 interface, without burner, convenient procedures for modifying and upgrading;
7)Control distance: Simple, close control requirements communicated by RS232, it is a one-to-one relationship between the computer and controller, the communication distance up to 10 m; Complex, remote control needs an external RS232 to RS485 module remote monitoring communication, it is a one-to-many relationship between the controller and computer; Communication distance up to about 1 km, each controller can be set to a different address, a computer can control up to 255 controllers, constitute RS485 remote monitoring system;
8) Stability of the system: Relay output with high-frequency filter circuit, a very small harmonic; Making the system has a very high stability and extremely long working life.

Use
1. Can control AC 220V voltage range of the implementation devices such as AC or DC devices, such as contactors, cylinder, and solenoid valve, Relays, heating wire, ordinary motors, bulb, LED string lights, general motors and other output loads on and off.
2. Can realize the weak control of a variety of exchange of strong electric loads off;
3. Serial remote real-time detection and control of power plants, automatic flower shop and other production site automatically, remote engine room and other equipment, such as lighting, power, audio, video, electronic access controls on and off, save the toil of manual operation, saving labor costs;
4. Can be used for centralized control of buildings, advertising, arena and industry lighting, sound and other multimedia devices, intelligent control home appliances switch and so on.
5. Can be used for computer to control a variety of external equipment switch;
6. Can be used for a variety of distributed control system, remote IO module, remote control system;
7. Can be used for a variety of sand table, buildings, bridges and other models' lighting control.
