8 Points Single Chip Microcomputer I/O Industrial Control Board with LED Nixie Tube Display

JMDM-LED8DIO
8 points single chip microcomputer I/O industrial control board with LED nixie tube display
Introduction
Product feature
1. I/O: 4 channels optoelectronic isolation digital quantity input: Input voltage range is DC 12V~24V; Can also be customized for 5 v (need special instructions before buying), input current is 5~10MA; Can be used to detect the external various signal of sensor input, such as optoelectronic sensor, infrared sensors, hall sensors, proximity switch, inching switch and other digital quantity input devices, etc; Digital quantity working station indicator: Each channel digital quantity input has one indicator light, convenient to observe the input point working condition;
4 channels transistor output: No mechanical delay, can be directly control: DC: 0 ~ 100 V DC; Each channel the maximum output current is 33A, output port status can be back to read;
2.4 manual buttons: Set up and adjust the input parameters, easy to operation.
3. Program download instructions: Connect the serial communication between computer and controller, use STC-ISP download software to download the compiled HEX file to the controller. (Note: The download process there is a manual process of power failure and power on).
4. System stability: Industrial grade lightning protection, strong resistance to electromagnetic interference, high reliability, no crash phenomenon. Relay output using high frequency filter circuit, produce minimal harmonic; The system has high stability and long service life.
5.3 kinds of working mode: Support independent control(according to the KEIL C language compile of program logic automatic control), RS232 serial port monitoring(need compile Upper computer and lower computer program), RS485 serial port monitoring 3 kinds of mode; When RS485 networking, need add a RS232 turn RS485 communication module.
6. Precise control of time: Can realize precise time control.
Application
1. Can replace small PLC + text display system within eight points: Used for small switch, digital control system and application of industrial occasions within 8 points, and with three digital tube display and four key input, and according to the requirements set the buzzer alarm, convenient to display demands, human-computer interface and parameter setting of occasion use.
2. At the same time can control 4 channels digital quantity input signals and 4 channels output load: Such as photoelectric switch, infrared sensor, close to switch, trip switch, key presses, etc; DC 0 ~ 100 V voltage range of executive components such as AC contactor, cylinder, solenoid valve, relay, heating wire, general motors, light bulb, LED lamp series, ordinary motor output load on and off, etc.
3. Can realize weak current control all kinds of AC strong current load on and off, and through digital tube display related state in real time.
4. Remote real-time detection and control of power plant to a serial port, such as automation workshop production site, the remote machine room equipment, lighting, power supply, audio, video, electronic entrance guard on and off, dispense manual labor, save labor costs.
5. Can be used in the centralized control of the building, advertising, gymnasium arena of industries such as lighting, audio and other multimedia equipment, intelligent home appliance control switch, etc.
6. Use for a variety of distributed control system, remote IO module, remote control system.
7. Can be used for computer control of peripheral photoelectric switch, infrared sensor, button signal, the equipment switch.
8. Can be used for minitype sand table, building, bridge model of the control.
9. Can realize programming: Production line count, reach a buzzer alarm conditions, and open or close some equipments etc, personalized of customers requirements. If customers programming is difficult, the technological process can be sent to us, our company can be on behalf of programming.
