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)
