Compact and Reliable Programmable PLC Real Time Controller

Compact and reliable programmable PLC real time controller

  I.
4 channels intelligent digital relay setting software introduction
    4 channels intelligent digital relays consists in setting software and 4 channels timing control relay(JMDM-RTC4MR), timing control relay setting software can set the work states of each relay by USB, one channel relay can set 20 timing, each timing can set on-off time, also can set each relay to realize weekly cycle, daily cycle, hour cycle, minute cycle and second cycle.

II.
4 channels intelligent timing control reply(JMDM-RTC4MR) hardware introduction
4 channels timing control relay(JMDM-RTC4MR) in independently researched and developed by Shenzhen Jingmin Digital Machine Co., Ltd, it is a high stable and reliable industrial PLC controller with real-time clock timing, the battery voltage detection automatic and charging function, and communicate with computer by USB realize 4 channels relay online or offline control function.

III.
4 channels relay output: Photoelectric isolation output can avoid electric instant incorrect operation, stable and reliable. The max loading AC voltage for relay contacts is 220V, the max loading current is 10A.

IIII.
Using rechargeable nimh batteries to power a clock chip, when the nimh battery voltage drops below the clock chip working voltage, the controller of the charging circuit can give automatic rechargeable nimh batteries.This avoids the controller because of time are not allowed to be resulted from the insufficient battery bad phenomenon.

Technical parameter
    1. Working power supply: DC12V, 1A, with anti-lightning protection circuit, stable and reliable.
    2. 32 bits high performance single chip microcomputer control: programme storage space: 128K and the data storage space: 64k(if there is special requirements), save date and it will not lose if the power is cut off.
    3. One communication interface
   One channel USB interface with ESD (Electrostatic discharge protection), it used to download the programme and communicate with computer and other upper computers.
    4. 4 channels relay output:
Photoelectric isolation output control can effectively prevent the product on the electric instant mis operation, stable and reliable. The relay contacts can load AC voltage 220V and the max output current is 10A.
    5.Programme download specification: Connect the USB communication cable between the computer and the controller, and download the compiled HEX file to the controller by the download software MCU-ISP.
    6. System stability :Has industrial grade anti-lightning,Strong resistance to electromagnetic interference, high reliability and no crash phenomenon.
    7. Two working types: Support control independent(Logic automatic control according to the programme write by Keil C language), serial port control
    8. Digital quantity working state indicator: Indicator in each digital quantity output used to observe the output working states.
    9. With FM24C16 ferroelectric memory EEPROM, the date will not lose if the power is cut off and it can save 16K user date.
    10.There is real time clock module embedded in the chip, we can realize real-time control through setting real-time time based on the requirements if user need precise timing.
