Electronic Data Systems

1. Introductions
JMDM-ARM29DIOMR is independently research and development by Shenzhen jingmin digital machine Co.,Ltd. With 17 channels optoelectronic isolation digital signal input and 12 channels relay dital output .High reliability and stability of industrial programmable logic controller, also called 29 points ARM processor I/O industrial control.
2. Performance parameters
1). Working power: DC12V - 24V 1A,controller board with lightning protection circuit board, stabilize and reliable.
2). 32 high performance single chip controller: Programme storage space:128K, data storage space:64K, data memory used to store data, the data will not lost after power failure.
3). One kind of communication interface: with RS232 interface, Can be used to upload programme and upper computer communication.
4). I/O:
17 channel optoelectronic isolation digital input: the input voltage range is DC 12 v ~ 24 v; Also can be customized for 5 v (before buying Special instructions), the input current is 5 ~ 10MA; Can be used to detect the external sensor input signals, such as photoelectric sensor,Infrared sensors, hall sensors, proximity switches, inching switch and so on digital quantity input devices, etc;
12 channel relay output:, Can effectively prevent the product on the electric instant misoperation, stable and reliable. Relay contact can withstand voltage is 220 v, the maximum output current for 10 a.
5), program download instructions: good connection between computer and controller serial communication line. Will use on STC - ISP download software compiled HEX file downloaded to the controller. (note: the download process there is a manual process of power and electricity). ;
6), system stability: with industrial-grade lightning protection, strong resistance to electromagnetic interference, high reliability, no crash phenomenon.
