JMDM-12DIO8AIO serial port control of the analog digital input and output control syetem, is a high-reliable stability
industrial-grade SCM control system which independent research and development by Shenzhen jingmin digital machine
Co.,Ltd. with the main feature of analog control, can also be called as JMDM-12DIO8AIO online momitoring communication
system, JMDM-RS485/232 serial port control analog system. Realized using the Computer serial port line monitoring of
the digital and analog input status; real-time control of the analog and digital output,support through RS232 serial port
to extension of I/O points, A/D and D/A points, can be used for the computer serial port to achieve the control of analog
and digital signal,experiment and a variety of industrial application .
2. Technical parameters and functions of JMDM-10DIO10AIO

output has overvoltage protection circuit, anti-lightning and static shock;
2) working power: AC 18V or DC 24V, having overvoltage protection and lightning static protection function.
3) Using the latest high-speed C8051 Series SCM.
4) Program memory space is 64K and data storage space is 32K.(use perfect ferroelectric memory technology);
5)Digital input and output section,analog section:
Full-optically isolated digital (I / O) section:
4-channel input: the input voltage is 12V~24V, the input current is 10MA,NPN type(Active-low);
6-channel output: the output voltage is 12V~24V, output current is 4A, NPN type;
(12 bit ) high-precision high-speed analog parts:
8-channel input: 0~10V voltage input, can customized for 0~5V voltage input format or 0~20MA current input format; having
overvoltage protection and lightning static protection function.
2-channel ouput: 0~10V voltage ouput, the ouput current is 20MA, can also be customized for 0~5V voltage output; having
overvoltage protection and lightning static protection function.
6) RS232 interface: 2-channel standard RS232 serial port communication interface, having the following merit:
Can support to communicate with two peripheral device or host controller (computer or PLC)at the same time.
support the function extension of I/O, A/D, D/A, Facilitate a variety of multi-channel digital and analog control
requirements;
7) circuit board production use of SMD soldering, stable and reliable.
8) simple needs with RS232 communication, Is a one-to-one relationship between the computer and the controller, the
communication distance up to 10 meters;
9) Complex needs can use RS485 communication, between the computer and the controller is one to many relationship; the
communication distance can up to about 1 km, each controller can be set to a different address,a computer or master PLC
can up to control 255 controller.
