Electronic Data Systems

1. Introductions
JMDM-ARM40DIOMR is independently research and development by Shenzhen jingmin digital machine Co.,Ltd. With 24 channels optoelectronic isolation digital signal input and 16 channels relay dital output .High reliability and stability of industrial programmable logic controller, also called 40 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). Two kinds of communication interface:
A. One channel with RS232 interface, Can be used to upload programme and upper computer communication.
B. One channel with RS485 interface, the max of communication distance is 3KM; As articulated in the network of 20 nodes.
4). I/O:
A. 24 channels 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;
B. 16 channels relay output:, Can effectively prevent the product on the electric instant misoperation, stable and reliable. Relay contact can withstand voltage is 220V, the maximum output current for 10A.
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). ;
