Human-Computer Interface Scm Controller with LCD Screen and Keyboard

JMDM-2038M
Introduction
JMDM-2038M is a multifunction human-computer interface and the single chip microcomputer controller all in one, the hardware adopts high performance, industrial grade of imports singlechip and spare parts, professional stability, anti-interference circuit design, software using C language programming, with good scalability and versatility. Can realize the IO, analog input and output, human-computer interaction of multi-function control of stepping servo motor.
Performance parameter
1). Control 18 I/O points, the whole optoelectronic isolation.
2). 2 channels pulse signal output, 2 channels direction signal output, at the same time can control 2 channels stepper or servo motor linkage.
3). 1 channel programmable frequency signal output, used in some speed control occasions.
4). 8 bits high-performance single-chip microcomputer as the main control chip, program space is 64k;
5). 32k bits data storage, can be used to save the parameters data, the data will not lost after power failure.
6). Reserve the IIC bus interface, can weld storage chip of 24C02 serial;
7). Controller power supply: Standard configuration DC 24V 1A switching power supply. Between DC 12V-30V (OR 9V-20V AV) all can run normally.
8). With 1 channel standard RS232 serial communication interface, can communicate with such as upper computer software, can also work online between multiple controllers. Can through the jumper cap switch to RS485 remote communication, can work with multiple controllers to realize the network unit.
9). Can download the program directly by RS232 interface, without CD-R machine, convenient program modification and upgrade;
10). System adopts photoelectric isolation and enable internal watchdog and strict high frequency filter characteristics, with professional power supply monitor circuit make the system stable and reliable work, no crash phenomenon;
11). 128*64 LCD blue screen; One screen can display 6*4 Chinese characters; Can also display graphics digital character, etc.;
12). With 10 tuch-button, can be set parameters online;
13). Appearance size: 150mm*145mm*55mm, installation size: 145mm*140mm, install with assorted copper card;
14). With Keil C programming, the user programming difficult can send the process flow to our company, we can help to develop the program.
Notice
1. Customer control panel will be in strict accordance with the wiring diagram connecting all finished, after checked can connect the power supply. Otherwise will burn out controller or external input/output devices.
2. Controller input signal is default the external DC 12 or 24V power supply.
Application
1). Can be used for the digital quantity input/output control system, can control cylinder, solenoid valves, relays, etc.; Can connect with external various kinds of photoelectric sensors, infrared switch.
2). Can control temperature, pressure, laser energy, frequency converter analog signal input and output, etc.
3). Can control stepping motor and servo motor.
4). Can also be used to replace the PLC to control the various occasions, such as all kinds of machine control, function more powerful and flexible than the PLC add text display. Stable performance, cost-effective.
Currently has been widely used in pneumatic cylinder, solenoid valve, relay, step and servo motor, multistage multi-channel temperature control requirements such as high precision, high speed of industrial environment and equipment, stable and reliable running, successfully survived the bad industrial environment of strong electromagnetic, high-frequency interference test, with high cost performance has won the broad customers trust, and sells in distant markets at home and abroad.
