1) Using ARM *2-bit architecture ™ - M3 CPU, **8 k flash program memory; *0 k SRAM. 2) Main power supply adopts *8V(or *4V dc), peripheral drive power use *4/*2V dc; 3) 8 Channels photoelectric isolation digital quantity input, NPN input form, the input current of *0 ma; 4) 4 channels relay output (can connect **0V voltage, maximum current is 5A), using photoelectric isolation and enable internal watchdog and rigorous high-frequency filtering characteristics, and make the system work stable and reliable, no crash phenomenon; 5) 1 channel to standard RS**2 serial communication interface (*5KV static shock resistance), can directly communicate with peripherals like computer or text display 6) Can download the program directly through the RS**2 interface, without CD-R machine, convenient program modification and upgrade; 7) With a lamp that LED lights display working status, there is a dial the code switch can be set according to the program state or parameters; 8) Shell install size: **5 mm x **0 mm x *0 mm; Available guide installed or installed with screws. Internal control panel size: length x width x height: *2 mm * *6 mm * *8 mm; 9) Can use Keil C or assembly programming, user programming is difficult can send the technological process to us, we can help programming. 2. specification A. Operating temperature: **0~**5°C； B. Storage temperature: **0~**0°C ； C. Humidity: 5~*5% without condense； D. Consumption(without peripheral equipment): **8V 0.5A (typical value). 3. Application 1) Can be used for a variety of within *2 points control system, can control cylinder, solenoid valve, relay, stepper motor, photoelectric converter, capacitance, inductance, all kinds of sensors such as hall type; 2) Can replace within *2 points PLC is used in various occasions (such as all kinds of machine control); 3) Can be used to ARM study and test. 5. After-sale service 1). under normal use, within one year from the date of purchase, JMDM controller appear quality problem to maintenance free; After the warranty maintenance charge maintenance costs. 2). transformer, serial communication lines and other free offer or belongs to consumable accessory, not in the warranty scope. 3). because of the forces of nature, artificial damage, not follow the instructions to use, improper operation, repairing, or beyond the scope of failure caused by abuse, etc, is beyond the scope of warranty. If you need to charge, will charge maintenance costs.
