 , 8-bit high-performance single-chip control: program memory space: 32K; data storage space: 16K (if a specific need), save the data, the power data is not lost. 
 3, two communication interfaces: 
 1) all the way to the RS232 interface, can be used to download programs and computers, the host computer communication; 
 2) all the way wireless WIFI interface: with WIFI PDA, laptop, Tablet PC or smart phone via the control interface can be directly wireless control. 
 4, the I / O: 
 12 opto-isolated digital input: Input voltage range for DC 12V ~ 24V; can also be customized to 5V (before buying otherwise noted), the input current of ~ 10MA; sensor input can be used for the detection of external signals, such as photoelectric sensors, infrared sensors, Hall sensors, proximity switches, jog switches and other digital input devices; digital status indicator: Each digital input has an indicator light, convenient to observe the working status of the input points; 
 Eight relay output: passive dry contact form, can directly control: AC 220V voltage, DC: 0 ~~ 30V voltage; each maximum output current of 10A, the output state can be read back; 
 5, download: Connect the serial communication line between the computer and controller. The use of the STC-ISP download software compiled HEX file to download to the controller. (Note: The download process is a manual power-off and power-on process). 
 6, the stability of the system: industrial-grade anti-lightning, anti-strong electromagnetic interference, high reliability, no crashes. Relay output with high-frequency filter circuit, resulting in minimal harmonic; system with high stability and extremely long working life; 
 7,3 kinds of work: support for independent control logic automatic control) (KEIL C language program, the RS232 serial port monitor (requires the preparation of PC, the next bit machine program), wireless WIFI monitoring three ways; 
 8 Dimensions: 
 Circuit board dimensions: length × width × height: 148mm × 105.5mm × 28mm; 
 Case dimensions: length × width × height: 155mm × 135mm × 60mm. 

 Third, programming 
 KEIL C programming environment, the company provides a programming paradigm, customers can develop applications on this basis, the second. 
 Control a single relay output points: 
 sbit OUT1 = P2 ^ 1; a relay output ports defined; 
 sbit OUT2 = P2 ^ 0; the definition of second relay output ports; 
 sbit OUT3 = P4 ^ 0; third relay output ports defined; 
 sbit OUT4 = P3 ^ 5; fourth relay output ports defined; 
 sbit OUT5 = P3 ^ 4; fifth relay outputs defined; 
 the sbit OUT6 = P3 ^ 2; sixth relay output port is defined; 
 sbit OUT7 = P4 ^ 3; seventh relay outputs defined; 
 sbit OUT8 = P1 ^ 7; eighth relay outputs defined; 
 OUT3 = 0; open the third relay; 
 OUT3 = 1; close third relay; 
 (2) read the input point of the command: 
 the sbit IN1 = P2 ^ 5; the first input point defined; 
 IN2 is = P2 ^ 4; second input point defined in the sbit; 
 the sbit IN3 = P2 ^ 3; the third definition of input points; 
 sbit IN4 = P2 ^ 2; fourth input point defined; 
 sbit IN5 = P1 ^ 6; fifth input point defined; 
 sbit IN6 = P1 ^ 5; the sixth definition of input points; 
 the sbit IN7 = P1 ^ 4; seventh definition of input points; 
 sbit IN8 = P1 ^ 3; inputs 8 point definition; 
 the sbit IN9 = P1 ^ 2; ninth definition of input points; 
 the sbit IN10 = P1 ^ 1; tenth definition of input points; 
 sbit IN11 = P1 ^ 0; tenth an input point defined; 
 sbit IN12 = P4 ^ 2; input 12 points defined; 
 if ((IN3 == 0) && (IN3 == 0)) to determine the third input signal is no signal input; 

 Fourth, the specification 
 1, operating temperature: -10 ~ +65 ° C; 
 2, storage temperature: -20 to +80 ° C; 
 Humidity: 5 ~ 95% non-condensing; 
 4, power consumption (no external device): +12 V 1A (typical); 

 Hardware connection Note 
 The power of JMDM-WIFI20DIO DC 12V ~ 24V 1A or AC 9V ~~ 18V 1A power supply. 
 2, the customer should be strictly in accordance with the wiring diagram of the control panel all the wiring is completed, and check the correct order to pass on power. Otherwise it will burn out the controller or an external input and output devices. 
 3, the input signal of the controller defaults to the external DC power supply 12 or 24V. 

 Six, the example of the host computer software instructions for use
