    3. Product feature:

    1) . Input and output: the maximum 4 channels input, 16 channels output, according to customer need to customize the input and output points.

    4 channels photoelectric isolation digital quantity input, NPN input form, the input current is 10MA, There are two way can interrupt source is used to count; 16 channels photoelectric isolation digital output, among 8 channels for NPN transistor output, the output voltage of 24/12 v, maximum current is under 4 a. Another eight road is PNP transistor output, the output voltage is 24/12V, maximum output current for 4A, the output state can be back to read;

    2). Input can be used for collecting 4 channels digital quantity/switching valve signal, such as photoelectric sensors, hall sensors, proximity switch, infrared sensor and digital signal input;

    Output can control 16 channels digital signals, such as: solenoid valve, cylinder, relay, LED lamp series, general motors executive device. Jingmin upper PC serial port control software provides the general applications of commonly used control output and input button, convenient customer use directly, the customer don't need to know any professional programming language, the direct use Jingmin Digital upper PC serial port control software can be realized the computer serial port control digital signal input and output, at the same time can provide upper PC serial port control VB sample application and communication protocol, convenient for the user on the basis of the second development, integration, can use within 20 channels the I/O study, experiment and industrial application.

    3). More than one network constitutes a large remote measurement and control system:

    By address coding and RS485 network, a main control computer max can addressing, control 255 controllers, a computer with 255pcs Jingmin dimming controller compose of large remote measurement and control system:controller between host computer and many controllers can be extended through the RS485 bus extend(the longest 1 km), so that the host computer can put away from the controller, realize remote network control.

    4). Customized requirements:

    It can customize according to customer's specific needs, meet the requirements of the customer diversification and personalized application function of the control system, upper PC control software, such as timing, loop automatic control system of digital quantity input and output; Set the logical relationship between input and output or programming.
