Single-Chip Microcomputer Controller

JMDM-20DIO4AIO 4 channels analog quantity 20 channels digital quantity single-chip microcomputer controller

Functional performance
1.8 bits high-performance single-chip microcomputer as the main control chip, six times the normal single chip microcomputer speed;
2. Main power supply use AC 9V, also can use DC 12V, irrespective of positive and negative power supply wiring;
3.12 channels photoelectric isolation digital quantity input, NPN input form, the input current is 10ma, There are two ways to interrupt source is used for high speed counting;
4.8 channels photoelectric isolation digital output: 4 channels is isolated relay output, can be directly connect 220V working voltage, maximum output current is 5A; Another 4 channels is photoelectric isolation transistor output, used for high frequency, maximum output current is 5A, can control the step motor and servo motor, the output frequency can reach 40KHZ, can use as PWM applications;
5.3 channels AD (analogue) input, the sampling precision is 8 bits, the sampling range is (0-10V); Can also be custom-made into (0-5V), with over-voltage protection, anti-static, etc;
6.1 channel DA (analogue) output, DA conversion accuracy is 8 bits, the output voltage range is (0-10V), can also be custom-made into (0-5V) output, with over-voltage protection function;
7.1 channel standard RS232 serial communication interface, and can communicate with upper software such as computer, also can work online between multiple controllers;
8. Can download the program by RS232 interface directly, without CD-R machine, convenient program modification and upgrade;
9. With 512 bytes of data storage, can be used to save the parameters such as data, data will not lost after power failure;
10. System adopts photoelectric isolation and enable internal watchdog and strict high frequency filter characteristics, make the system stable and reliable work, no crash phenomenon;
11. Compact chassis, controller casing size: 145 mm * 100 mm, can use screw to install or guide installation;
12. With Keil C or assembly programming, user programming is difficult can send the process flow to our company, we can help to programming.
Performance parameter
1. Working temperature: -10 ~ + 65° C;
2. Storage temperature: -20 ~ + 80° C;
3. Humidity: 5 ~ 95% without condensation;
4. Power consumption (no external devices): +12V @ 0.5A (typical);
Attention
1. Customer must pay attention to in strict accordance with the product manuals attached behind the wiring diagram connected controller board, carefully check again after confirmed, then can connect power supply, otherwise will burn controller or external input/output devices;
2. Controller input signal default using DC 12V/24V power supply.
Application
1. Can used for all kind of within 20 points control systems, can control cylinder, solenoid valve, relay, stepper motor, photoelectric converter, capacitive, inductive, hall various sensors type;
2. Can be used to replace within 20 points of PLC to control the various occasions, such as all kinds of machine control.
3. Can be used for analog output or analog detection applications;
4. Can be used in the single-chip computer study and test.
