IC694ALG220是GE Fanuc生产的4通道模拟电压输入模块。它提供四个模拟输入通道，并接受-10至+10伏特范围内的输入。通过跨接输入端子，单个通道可用于4至20 mA输入。每个通道的转换速度为1毫秒，任何通道的更新速率为4毫秒。该模块可以安装在RX3i PLC系统的任何I / O插槽中。

如果IC694ALG220位于RX3i通用背板中，则需要外部+24 VDC隔离电源为模块供电。外部电源必须通过背板左侧的TB1连接器进行连接。如果此模块位于扩展底板中，则电源将提供所需的隔离+24 VDC输出。当电源按预期运行时，模块正常LED指示灯将亮起。

与模块的所有现场连接均应使用适当等级的双绞屏蔽仪器电缆进行布线。这将使电容性负载和噪声*小化。屏蔽层可以连接到COM或GND。COM连接提供对模拟电路公共端的访问。GND连接提供对背板（机架接地）的访问。此外，如果电压源悬空以限制共模电压，则电压源的（-）侧可以连接到COM端子。

The IC694ALG220 is a 4-channel analog voltage input module manufactured by GE Fanuc. It offers four analog input channels and accepts inputs in the -10 to +10 volt range. By bridging the input terminals, a single channel can be used for 4 to 20 mA inputs. The conversion rate for each channel is 1 millisecond, and the update rate for any channel is 4 milliseconds. The module can be installed in any I/O slot of the RX3i PLC system.

If the IC694ALG220 is located in the RX3i universal backplane, an external +24 VDC isolated power supply is required to power the module. The external power supply must be connected through the TB1 connector on the left side of the backplane. If this module is located in the expansion baseboard, the power supply will provide the required isolation +24 VDC output. When the power supply is operating as expected, the module normal LED will light up.

All field connections to the module shall be routed using the appropriate grade of twisted-shielded instrument cable. This minimizes capacitive load and noise. The shielding layer can be connected to COM or GND. COM connections provide access to the common end of the analog circuit. The GND connection provides access to the backplane (rack ground). In addition, if the voltage source is suspended to limit the common-mode voltage, the (-) side of the voltage source can be connected to the COM terminal.
