1. Product synopsisJMDM-COM20MR is a high reliable stability of industrial single-chip digital serial controller, relay controller,Onboard 20 10A large - capacity relay which independent research and development by Shenzhen jingmin digital machine Co.,Ltd. it is focused on the 20-channnal 10A of large load control, such as lightning, heating wire, power switch, and the other high-power devices, and collect 4-channel I/O input signal contemporary; Can be connected photoelectric, capacitive, inductive, Hall-style and a variety of sensors and input switch, convenient to plenty of industrial and civil application occasion of stroke switch, infrared switch of the signal detection and condition input to control the output action. The products have following characters:1). Product design and quality: professional industrial-grade high reliable of lighting prevention and anti-strong electromagnetic interference circuit design, the circuit layout compact and reasonable, with excellent heat dissipation, majority use of patch type chips and electronic components, the product procedure with high security, with relaible industrial quality and stable performance, competence to all kinds of large electromagnetic interference and harsh environment industrial sites, such as arc current, welding current, inverter, and the other workplace can be stable used.2). I/O: 4-channel full Opto-isolated input and 20-channel relay output; output with super load capacity;(1) Each of the 20-channel relay are fetch out a normal open point and normal close point, it can control 20 groups of diferent voltage switch;(2) Each channel relay output the maximum load is 220V 10A, output use special high filter circuit to prevent electric shock ignition, Increase the life of relay.(3) Two kinds of communication interface is optional: an RS485 interface and an RS232 interface optional;(4) Three kinds of working methods: Support for independent control, RS232 serial port monitor, RS485 serial monitoring.(5) Four toggle switches: direct hardware addressing to facilitate multiple network use;(6) The precise time control: with the system clock enables precise time control;(7) System stability: with industrial-grade anti-lightning, anti-strong electromagnetic interference, high reliability, no crashes.(8) Relay working status indicator: Each relay output has a indicator light that easy to observe the working status.(9) Industrial shell, dustproof, easy for installation: rail or screw mount;(10) Simple serial communication protocol, the convenience of customers for the secondary development2. performance parameters1) Working power: workong power of the controller: AC12V or 24V；AC or DC universal; input points Power supply: DC5V ~ 30V, Output points powersupply: 0 ~ 220V AC or DC;2) The main control chip: Eight high-performance single-chip-microcomputer plus high speed and high stabile FPGA programmmable gate array circuit.3) Program storage space: 32K (If there is a specific need, can use 64 K); 4) Data storage space: 16K (If there is a specific need, can use 32 K): save the date, data is not lost after power failure;5) Input and Output: 4-channel full opto-isolated digital inputs, NPN input forms, maximum input current is 10 MA; of which two can be used as an interrupt source used to count, 20-way relay outputs, each output carries a maximum voltage of 220V, Maximum current is 10A, Output using a unique high-frequency signal filter circuit to prevent contacts ignition, increase the life of the relay; Each channel of 4. Usage1) Can be controlled 0 ~ 220V voltage range AC or DC actuator such as cylinders, electromagnetic valves, relays, heating wire, general motors, electric light guns, LED string lights, general motors and other output load through broken;2) Can realize the weak control of the strong electric load off;3) Can be serial remote real-time status monitoring and control of power plants, automated workshops, and other production sites, remote engine room equipment, such as lighting, power, audio, video, electronic access control of on and off, to save the manual laboring, saving labor costs;4) Can be used for centralized control of the building, advertising, Arena and industry lighting, sound and other multimedia devices, intelligent control home appliances switch.5) Can be used for computer to control a variety of peripheral equipment's on and off.6) can be used for a variety of distributed control system, remote IO module, remote control system.7) can be used for a variety of sandbox, buildings, bridges and other module of control.8) can be used for the control of electronic lock, infrared switches, door sensors, automatic door.9) can be used for machine control, input and output of the logic timing control, the function, expansibility, cost-effective of it are superior to the OLC with 24 points PLC.
