Industrial grade serial port controller, 4 channels optoelectronic isolation digital quantity input 20 channels transistor output

Introduction
JMDM-COM20MT is shenzhen jingmin digital machine Co., Ltd., independent research and development with high reliability and stability of industrial microcomputer serial digital controller, transistor controller.
1. Product design and quality: Professional industrial high reliable and strong resistance against lightning electromagnetic high frequency interference circuit design and circuit layout is compact and reasonable, good heat dissipation and use patch type more chips and components, high confidentiality, industrial quality reliable products, stable performance, can be competent for all kinds of electromagnetic interference, industrial site conditions, such as arc current, welding current, frequency converter and other workplace can use stable.
2. I/O: 4 channles whole photoelectric isolated input, 20 channels relay output; The output with superstong load capacity:
1) 20 channels of each channel transistor elicit a normally open and normally closed, can control 20 groups different voltage switch;
2) each channle transistor output maximum load 24V 10A;
3.2 kinds of communication interface optional: 1 RS485 interface and 1 RS232 interface can be selected;
4.3 workings: Support independent control, RS232 serial port monitoring, RS485 serial port monitoring;
5.4 toggle switches: Can be directly addressing hardware, convenient multi-networkings use;
6. Precise time control: With the system clock, it can realize accurate control of time;
7. System stability: The industrial-grade lightning protection, strong resistance to electromagnetic interference, high reliability, no crash phenomenon.
8. Transistor working status indicator light: Every channel relay output has an indicator light, convenient observation work status;
9. Industrial case, dustproof and beautiful, convenient installation: The installation guide rail or screw hole.
10. Serial port communication protocol is simple, convenience customer the secondary development.
Application
1. Can control within 0 ~ 220V voltage range the execution of all kinds of AC or DC components such as cylinder, solenoid valve, relay, heating wire, general motors, electric lamp, LED string lights, ordinary motor output load and broken;
2. Can realize week current control strong current load on and off;
3. Can serial port remote real-time monitoring and control power plant, automatic workshop production site, the remote machine room equipment, lighting, power supply, audio, video, electronic entrance guard opened and shut, dispense of manual labor, save manpower cost;
4. Can be used in the centralized control building, advertising, gymnasium industries such as lighting, audio and other multimedia devices, intelligent control home appliances switch, etc.
5. Can be used for computer control of peripheral equipment switch;
6. Use for a variety of distributed control system, remote I/O module, remote control system;
7. Can be used for all kinds of sand table, such as building, bridge model of the control.
8. Can be used in the electronic lock, infrared switch, induction door, automatic door control;
9. Can be used in the mechanical control, input/output logic sequential control, its function, scalability, and cost performance is better than 24 points of PLC;
10.4 channel digital quantity input point can meet photoelectric, capacitive and inductive, hall various sensors type input switch;
11. Using a computer serial port control, easy realize: Remote, centralized real-time condition monitoring and control of strong current, multi-channels lighting, power supply, audio or video switch, entrance guard switch on and off of digital signal; Serial port collect, display, back to read all kinds of switch signal state;
