概述
I/O模块连接到GX/GP，可扩展
I/O单元、GM主单元和GM子单元。
●一个模块类型有7种，模拟输入、模拟输出、数字输入、数字输出、数字输入/输出和脉冲输入PID控制*。
*关于GX90UT PID控制模块，请参见GX90UT PID控制模块通用规格(GS 04L53B01-31EN)。
●输入输出采用模块化结构，可方便扩展。
●GX90XA模拟输入模块有以下几种类型;(1)通用型，允许测量输入为DCV(直流电压)、TC(热电偶)、RTD(电阻温度检测器)和DI(接触或TTL电平电压);(2)电流输入型，内置分流电阻，可直接输入4- 20ma的标准直流信号;(3)电磁继电器扫描型，不受噪声影响，允许测量输入为DCV、TC和DI;(4)低耐压继电器型，提供低成本;(5)高耐压型，输入端子与地之间的耐压为600v。
GX90XA-04-H0高速模拟输入模块可以测量DCV(直流电压)，TC(热电偶)，RTD(电阻温度检测器)，DI(接触或TTL电平电压)输入，最短间隔为1ms。它有一个A/D转换器为每个输入通道，并采用无扫描仪的方法，这是不太容易受到高频噪声。
GX90XA-06-R1 4线RTD/电阻输入模块可以接收4线RTD或4线电阻的输入。在每个系统中，一个测量输入信号可以分配给每个通道。
●GX90YA模拟输出模块具有多种通道的重传输出和手动输出功能。它通过隔离通道提供电流输出。
●GX90XD数字输入模块，允许多达16个数字输入或脉冲输入，可作为多点数字输入或脉冲输入。该模块还可以作为远程控制输入。
●GX90YD数字输出模块被指定为继电器输出(触点C)，当报警激活时使用。它也可以用来手动打开和关闭输出使用触摸面板。
●GX90WD数字输入/输出模块提供8个数字输入或脉冲输入和6个继电器输出。当有少量的数字输入和数字输出时，不需要安装两个模块。这样可以实现有效的通道配置。
●GX90XP脉冲输入模块最多可接收10个脉冲输入。最大输入频率为20khz。该模块可用于集成来自流量计或类似设备的脉冲信号
*集成需要数学功能(/MT选项)。

OVERVIEW
I/O modules are connected to the GX/GP, Expandable
I/O unit, GM main unit, and GM sub unit.
● A module type is seven types, an analog input, a analog output, a digital input, a digital output, a digital input/output and a pluse input PID control*.
* For the GX90UT PID Control Module, please see GX90UT PID Control Module General Specifications (GS 04L53B01-31EN.)
● Input and output have module structure and it can extend them easily.
● The GX90XA analog input module has the following types; (1) universal type that allows the measurement input for DCV (direct voltage), TC (thermocouple), RTD (resistance temperature detector), and DI (contact or TTL level voltage), (2) current input type with the built-in shunt resistor to directly input a standard signal of 4-20mA DC, (3) electromagnetic relay scanner type insusceptible to noises that allows the measurement input for DCV, TC, and DI, (4) low withstand voltage relay type that offers a low cost, (5) high withstand voltage type that 600 V withstand voltage between input terminal and ground.
The GX90XA-04-H0 high-speed analog input module can measure DCV (DC voltage), TC (thermocouple), RTD (resistance temperature detector), DI (contact or TTL level voltage) inputs at the shortest interval of 1 ms. It has an A/D converter for each input channel and employs a scannerless method, which is less susceptible to high frequency noise.
The GX90XA-06-R1 4-wire RTD/resistance input module can receive input from 4-wire RTDs or 4-wire resistors. In each system, a measurement input signal can be assigned to each channel.
● The GX90YA analog output module is capable of retransmission output of various types of channels and also manual output. It provides current output with channels that are isolated.
● The GX90XD digital input module, which allows up to 16 digital inputs or pulse inputs, can be used as a multipoint digital input or pluse input. This module can also be used as a remote control input.
● The GX90YD digital output module is assigned as a relay output (contact C) and is used when an alarm activates. It can also be used to turn the output on and off manually using the touch panel.
● The GX90WD digital input/output module provides eight digital inputs or pulse inputs and six relay outputs. When there are small amounts of digital inputs and digital outputs, you do not need to mount two modules. This enables efficient channel configuration.
● GX90XP pulse input module can receive up to 10 pulse inputs. The maximum input frequency is 20 kHz. The module can be used to integrate pulse signals from flowmeters or the like.*
* Integration requires the math function (/MT option).
