AC/DC; Peripheral drive power supply: DC12V or DC24V;

2.Main control chip: 8 bits high-performance single chip microcomputer 

with high-speed high stable FPGA programmable array circuit.

3.Program storage space: 32K (if you have specific needs, can be 64K);

4.Data storage space: 16K (if you have specific needs,can be 32K), save 

the data,the data will not lost after power failure.

5.Input and output: 4 channels photoelectric isolation digital quantity 

input, NPN input form, the maximum current input is 10MA, There are two 

way to interrupt source is used to count; 20 channles relay output, each 

channel the maximum voltage is 220V,maximum current output is 10A ; 

Output USES the characteristic of the high frequency signal filter 

circuit to prevent contact lighter, improve relay lifetime; Every channel 

relay to elicit a normally open and normally closed, can control 20 

groups different voltage on and off; Every channel relay has a patch type 

high brightness LED lights display relay working state;

6.Precise time control: with the system clock, by programming year, 

month, day, hours, minutes, seconds, and so on system operation;

System stability: adopting the enable internal watchdog and strict high 

frequency filter characteristics, make the system stable and reliable 

work, crash since the start time within 1ms;

7. 2 kinds of communication mode (interface) optional: 1 RS232 interface, 

1 RS485 interface can be through the short circuit cap choice.

1 channel standard RS232 serial communication interface (15KV static 

shock resistance), can be directly communicate with computer or text 

display peripherals; Can download the program RS232 interface, without 

CD-R machine, convenient program modification and upgrade;

1 road standard RS485 communication interface (15 kv static shock 

resistance and the lightning), can be used for the RS485 communication;

8.Controller working status indication: 2 LED lights display;

9.4 toggle switch, can be directly addressing hardware, convenient multi 

networking use; Controller can also be addressed by the software;

10.2 dial switch: can be set according to the application program state 

or parameters;

11.Industrial shell, dustproof and beautiful, the integration of compact 

design, easy installation, installation guide rail or screw hole;

12.Overall dimensions: shell: length*width*height: 146 mm x 90 mm x 40 

mm; internal control panel: 245 mm x 102 mm x 40 mm;

(extend read: JMDM series I/O industrial microcontroller serial port 

controller has a variety of optional:

According to the I/O points: 12/8, 16/12, 4/20, 4/16, 4/20, etc., models 

are:MDM-20DIOV2,JMDM-28DIOMT/MR,JMDM-COM20MR,JMDM-4DI16DO,JMDM-

40DIOMR;

All output: JMDM-COM40MR/MT, JMDM-COM8MR, etc.)

Product features:

1.Product design and quality: professional industrial high reliable and 

strong resistance against lightning electromagnetic high frequency 

interference circuit design and circuit layout is compact and reasonable, 

good heat dissipation and use patch type more chips and components, high 

confidentiality, industrial quality reliable products, stable 

performance, can be competent for all kinds of electromagnetic 

interference, industrial site conditions, such as arc current, stable 

welding current, frequency converter and other workplace can be used.

2, I/O: 4 channels whole photoelectric isolated input, 20 channels relay 

output; The output with super load capacity:

1) each channel of 20 all lead to a normally open and normally closed,can 

control 20 groups different voltage on and off;

2) each relay output maximum load is 220A 10A, the characteristic of the 

high frequency signal filter circuit to prevent contact flint, improve 

relay lifetime;

3. 2 kinds of communication interface optional: 1 RS485 interface and 1 

RS232 interface can be chosen;

4. 3 workings: support independent control, RS232 serial port monitorinf, 

RS485 serial port monitoring;

5. 4 toggle switch that can be directly addressing hardware, convenient 

multi networking use;

6.Precise time control: with the system clock, which can realize the 

precise time control;

7.System stability: with industrial-grade lightning protection, strong 

resistance to electromagnetic interference, high reliability, no crash 

phenomenon.

8.Relay working status indicator light: every channel relay output has an 

indicator light, convenient observation work status;

9.Industrial shell, dustproof and beautiful, convenient installation: the 

installation guide rail or screw hole.

10.Serial port communication protocol is simple: send string or ASCII 

code directly (many plagiarist is tedious lengthy code)
