1. Introduction

Suitable for digital quantity under 20 channels of the demand for small PLC control of industrial occasions, direct to use the software GX programming with mitsubishi ladder diagram, have power to maintain and online monitoring functions, with lightning protection, strong electromagnetic interference resistance, stable and reliable, highly cost-effective, simple and easy for use, can instead of foreign brands of PLC used in various control occasions within 20 points, the application of mitsubishi FX1N; Can be flexible used in all kinds of industrial automati control occasions, such as metallurgy, chemical, plastics, printing, textile, food, packaging and other industries in the production of machinery, industrial assembly line, all kinds of machine tools in the industrial control equipment.

2. Function

(1). Programming software is compatible with Japan's mitsubishi GXDeveloper ladder diagram software, in the application is equal to mitsubishi FX1N (C);

(2). Working power supply: with the lightning protection circuit. Can be worked under the DC 12V or 24V. Working power universal current (AC 9V or AC 18V can also work). Working voltage depends on the board of the relay coil.

(2). The PLC board has 20 channels optoelectronic isolation I/O input and output, 12 channels input, 8 channels output.

(3). The machine adopts high-performance imports of industrial grade chip design, can adapt to high electromagnetic interference industrial environment (250A discharge welding occasion to work normally.

(4). High speed operation, basic instruction 0.5 uS per step.

(5). Communication interface with RS232 (15 kv static shock resistant)

(6). 8000 step program register.

(7). Programming language adopt ladder diagram, using circular scanning working mode.

(8). Shell adopts screw or guide installation, integration of compact design. Shell size: length x width x height: 146 mm * 90 mm * 41 mm; Internal control board size: length x width x height: 123 mm * 87 mm * 24 mm;

(9). System adopts photoelectric isolation and enable internal watchdog and strict high frequency filter characteristics, with professional power supply monitor circuit make the system stable and reliable work.

(10). Can on-line monitoring, convenient debugging and fault diagnosis.

3. Usage

(1). Programming software: Use with the product attached to the Mitsubishi GXDevelopment, selection of PLC type is: FX1N (C);

(2). Working power supply: With the lightning protection circuit; mixed type output need single 24V(1A) DC power supply or double 9V(1A) AC power supply,4 channels relay output need 24V or 12V, universal current.

(3). Light: one, running lights.

(4). Control board has a toggle switch, toggle switch going (ON) for programming, the operation indicator light point not flashing, playing up (OFF) for running state, when the running lights flicker interval of 500 ms.

(5). Input/output description: 12 channels whole photoelectric isolation digital quantity input, input of NPN, low level effectively; 8 channels relay output for relay output form, the maximum operating current is 8A, the maximum working voltage is 220V, the relay has 12V and 24V , determines the working power supply of the controller, relay life is 200000 ~ 400000.

(6). Can monitor online, convenient debugging and fault diagnosis.

(7). Easy to install, use convenient installation fixed hole. The integration of the compact design.

(8). Controller download program to choose range setting, such as 2000 steps; not more than 8000 steps.

(9). Program at the END to END with END statement.

4. Application

1). Can be used for a variety of control systemwithin 20 points, can control cylinder, solenoid valve, relay, can be external photoelectric, capacitive and inductive, Hall type and so on various sensors;

2). Can be used to replace the foreign brands of PLC within 20 points to control the various occasions (such as all kinds of machine control), high cost-effective.

3). Can be used in the study and test of PLC.
