Product Description

JMDM-28DIOMR

Automatic scrolling advertising light boxes/scroll type automatic in advertising light box control system, single controller board

Introduction

JMDM-RS232 serial port control relay(transistor) board is is Shenzhen Jingmin Digital Machine Co., Ltd. independent research and development of industrial controller with high reliability, can be used for a serial port control of all kinds of digital quantity/switching value signal input and output. Can achieve the following functions:

1.Collected by the controller switch signal input state, through a serial port on the upper PC monitor interface of real-time display to the computer.

2.Through the computer serial port control relay (or transistor) on and off, to implement the control of the various switching value on and off.

In all kinds of civil, industrial, has very extensive application value, with the strong electromagnetic interference resistance, lightning protection, the characteristics of stable and reliable, can be applied to all kinds of conditions of industrial and civil occasions, with excellent and high cost performance to win the majority of customers respected and loved.

Product feature

1.JMDM-RS232 serial port controller is used to relay(or transistor) open and close.

2.Upper machine (PC or PLC) via a serial port to connect to the controller,sends a string of ASCII code instructions to controller can control some (or all) relays' open and closed, entirely unnecessary to consider the hardware circuit of relay selection and driver, etc. For example,serial port input O(002, 1) then No. 2 relay electric actuation; Serial input "O(012, 0)", then No. 12 relay power-lossing.

3. This serial port controller can also remote input point collection status, for example, the controller via serial port to send out I(004, 1) means the fourth entrance point with signal input,serial port send out I(011, 0) means No.11 entrance point wihtout signal input.

4. Serial port controller and the control host computer distance may be extended by 485 bus, the longest networking can reach a kilometre;

5. A single serial port controller can be independently controlled 12 channels relay (or transistor) open and close, can also be collected 16 state of the input point. Through the address code, in the case of a delay of 1 second, a serial port can be addressed, control a maximum of 255 pieces of serial port controller, constitute a 4080 input points, 3060 output points of large system.

6. Can provide a serial port communication protocol and communications VB source program, giving the VB through RS232 serial port operation or to develop special program.

Usage

1.According to the wiring diagram attached to the manual connect between the controller and the device, the serial communication line between computer and controller;

2.After carefully check and correct, connect the power of the controller;

3.Installation with attached to a serial port control software product:

Double-click JMDM serial port controller PC program SETUP \ SETUP file, or double-click directly JMDM serial port controller PC program SETUP\support\SETUP file.

4.Open the upper PC software, can click on the control input and output points.

Notice

1. Customer shall be in strict accordance with the wiring diagram connect control panel wiring out, after check and correct, then connect the power supply. Otherwise will burn out controller or external input/output devices.

2. Controller input signal default use external DC 12 or 24V power supply.

Application

1.Use for a variety of distributed control system;

2.Used in a variety of remote measurement and control system;

3.Can be used for building, advertising, such as lighting control, power control, automation workshop of large and medium-sized control project;

4.Can be used as a remote I/O module;

5.Can be used for computer control of peripheral equipment.
