Whole Optoelectronic Isolation Digital Quantity Switching Value Industrial Controller with 20 Channels

JMDM-20DIOV2MT
20 points IO serial port controller, whole optoelectronic isolation digital quantity switching value industrial controller
Introduction
JMDM-20DIOV2MR/MT serial port control relay (transistor) board used for serial port control of all kinds of digital quantity/switch signal input and output. To achieve the following functions:
1. Through controller collected switch signal input state, serial port on the 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 signal.
In all kinds of civil, industrial, with very extensive application value, strong electromagnetic interference resistance, lightning protection, the characteristics of stable and reliable.
Product feature
1. JMDM-20DIOV2MT serial port controller is used to transistor the opening and closing.
2. Upper machine (PC or PLC) via serial port to connect to the controller, the controller sends a string of ASCII code instructions can control some (or all) of the relay is open or 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 suction; Serial port input O(012, 0), then No. 12 relay power losing.
3. This serial port controller can also collection remote input point status, for example, the controller via a serial port to send out the I(004, 1) said No. 4 entrance point with signal input, serial port send out the I(011, 0)means No. 11 entrance point without signal input.
4. Serial port controller and the control of distance between the host computer may be extended by 485 bus, the longest network can achieve 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 license, 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 demo controller through RS232 serial port operation or to develop special program.
7. JMDM-20DIOV2MR/MT can according to customers' special requirements input and output, input order within12 channels, output order within 8 channels, typical customized products are: JMDM-8DIOV2MR/MT, JMDM-10DIOMR/MT, JMDM-12DIOV2MR/MT, JMDM-14DIOV2MR/MT, JMDM-16DIOV2MR/MT, JMDM-18DIOV2MR/MT, etc.
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 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 PC software, can click on the control input and output points.
Application
1. 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.
