Io Motor Controller with Small LCD Display

JMDM-20DIODISP
Introduction
JMDM-20DIODISP is a practical small LCD IO control and stepper motor control all-in-one.
Performance parameter
1. Mmain power supply: AC 18V or DC 24V, peripheral drive power supply: DC 24/12V;
2. Chips and storage space:
The main control chip: 8 high-performance single chip microcomputer;
Storage space: 32K (if you have specific needs, can be 64K);
The internal data storage: 16K (if you have specific needs, can be 32K),
External scalable data storage space: 256 k, can be used to save the data, the data is not lost power;
3, I/O:
12 channels photoelectric isolation digital quantity input, NPN input form, the maximum input current of 10MA, There are two way to interrupt source is used to count;
8 channels photoelectric isolation digital output, 4 channels relay output (can be an external 220V
Voltage, maximum current is 5A), 4 channels output transistor, open collector output form, an external voltage of 24/12V, maximum output current for 4A, the output state can be back to read;
4. The shell adopts screw or guide installation, integration of compact design, the size is as follows: The shell size: Length x width x height is: 154mm*126mm*60mm; Installation dimensions: Length x width: 145mm*100mm;
5. Use Keil C or assembly programming, customer use programming is difficult can send the process flow to us, we can help programming.
Product feature
1. Support the timing function: There is standby power supply system clock, could be on (date) (month) (year) minutes time to read and write operations, can be used for timing and time;
2. Blue LCD screen display: LCD screen size: Length * high: 53mm*14mm, 2 rows can be shown, each line 16 characters, each character is 8*5 lattice;
3. With 5 function buttons: Programmable parameter setting function, convenient for the user to modify the parameter value;
4. Adopting photoelectric isolation and enable internal watchdog and strict high frequency filter characteristics, make the system stable and reliable work, no crash phenomenon;
Usage
1. With 1 standard RS232 serial communication interface (15KV static shock resistance), can be directly communicate with computer or text display peripherals;
2. Can download the program directly by RS232 interface, without CD-R mahine, convenient program modification and upgrade;
3. Two LED lights: LED1 is the power supply indicator, LED2 programmable definition;
4. Two dial the code switch: Set in the program can be used as two parameters, such as the program status or function parameters;
Attention
1. Customer shall be in strict accordance with the wiring diagram will connect all control panel wiring out, and check and correct, then can connect the power supply. Otherwise will burn out or external input/output devices such as controller.
2. The controller input signal is the default use external DC 12 or 24V power supply.
Application
1. Can be used for a variety of within 20 points control system, can control cylinder, solenoid valve, relay, stepper motor, photoelectric converter, capacitive and 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 single chip microcomputer to study and test.
