Economical Feed Controller

JMDM-LCD8DIOMT 4 channels input and 4 channels output 32 bits single chip microcomputer I/O industrial controller, economical feed controller
Introduction
JMDM-LCD8DIOMTis independent researched and developed by Shenzhen Jingmin Digital Machine Co., Ltd, it is a high stable and reliable industrial PLC controller with 4 channels photoelectric isolation digital quantity input, 4 channels photoelectric digital quantity output, realtime clock for precise timing and 192*64 LCD screen.
Technical parameter
1. Working power supply: DC12V-24V 2A, has against lightning protection circuit, stable and reliable
2.32 bits high performance single chip microcomputer control: Programme storage space: 128/384K; Data storage space: 64K, save date and it will not lose if the power is cut off
3. Communication interface
One channel RS232 interface, it can be used to download the programme and communicate with computer and other PC
One channel RS485 interface, it can realize 485 network communication, the communication distance can be up to 100m.
4. I/O:
1)4 channels photoelectric digital quantity input: Input voltage range is DC12V-24V; Also can customized in 5(please special inform before purchase), input current is 5-10mA, it can be used to detect the input signal of the external sensors, such as photoelectric sensors, infrared sensors, hall sensors, proximity switches, switches and other digital quantity input device.
2)4 channels photoelectric digital quantity output: An open collector (transistor) output, the max output current is 5A, can be used to control air cylinder, electric valves, relay etc., output frequence can be up to 20KHZ
5.7 high stable light touch button can set the parameter online.
6.192*64 blue screen display: It can display 12*4 words per screen, also can display picture, number and symbol etc.
7. Download the programme: Connect the seral port communication cable between the computer and the controller, download the HEX file to the controller by MCU-ISP download software; (Notice: There is off-on process by hand during the period of the download)
8. System stability: Has industrial grade lightning protection, strong resistance to electromagnetic interference, high reliability and no crash phenomenon.
9.2 work type: Support work independent(Logic control automatic based on the programme wrote by Keil C language), RS232 serial port monitor.
10. Control two channels stepping motors or servo motors, pulse frequence is 200KHz
11. Digital quantity work states indicator: Indicator per channel used to observe the working condition more convenience.
12. FM24C16 ferroelectric memory EEPROM can save more than 128K user data, and it will not lose if the power is cut off.
13. There is real time clock on the chip, if user has precise timing requirements, we can set real time time in order to realize real time control based on the requirements.

Programme
Our company can provide programme example based on Keil C programme, based on that user can develop the applicant programme

Application
1. Can used in all kinds control system within 8 channels, control air cylinder, electric valves, relays, stepping motors and all kinds of sensors such as photoelectric type, capacitive type, inductive type and hall type
2, Can used to replace PLC within 8 channels and used in all kinds control(such as all kings machine control), equivalent 8 channels PLC plus text display.
3, Seral port real time remote monitor the states of the electric equipment, save the toil of manual operation and labor costs.
4, External connect one channel or two channels limited switch, light sensation as position detecting, make up single Axis or two Axis close-loop control system.
5, Control stepping motor or servo motor
6, Used to learn and test STM32
7, Typical application: Bag making machine, feeder, the printer etc.
