GE Fanuc的IC694ALG390模拟输出模块仅带有2个输出通道，但它可以连接到GE Fanuc在GE RX3i PacSystem产品线中制造的任何CPU。IC694ALG390模拟输出模块也是GE RX3i PacSystem设备。该模块可用作GE RX3i PacSystem PLC中的输出组件，并安装在GE RX3i串行扩展背板或GE系列90-30扩展背板中。但是，此模块不支持热插拔，也就是说，在背板通电时，它不能安装在任一类型的背板上或从背板上卸下。尝试热插拔IC694ALG390模拟输出模块可能会导致诸如损坏模块或背板、导致整个 PLC 突然停止或故障或严重伤害用户等问题。

IC694ALG390由GE Fanuc为Rx3i PacSystem制造。IC694ALG390是一个2通道模拟模块，具有两个输出通道，能够转换数字数据。通道在每次扫描后以大约 5 毫秒的更新速率更新。如果 CPU 因任何原因重置或进入停止模式，IC694ALG390模块输出可以配置为默认或保持最后状态。

IC694ALG390的电压范围为 -10 至 +10 伏。外部电压范围为 18VDC 至 30VDC，外部电压纹波为 10%。在分析电源时，模块的位置很重要。如果模块位于 RX3i 通用背板中，则需要隔离 +24 VDC 的外部电源来提供模块电源。如果模块位于扩展背板中，则其主电源可以是背板电源的隔离 +24 VDC 或连接到接线端子的外部隔离 +24 VDC 电源。如果外部电源介于 27.5-30 VDC 之间，它将从隔离式 24 VDC 系统电源接管模块的负载。如果用户需要在背板断电期间保持最后状态操作，则应使用外部电源。

现场连接应使用适当等级的双绞屏蔽仪表电缆进行接线，以最大程度地减少容性负载和噪声。屏蔽应连接到用户终端连接器块上的 GND。GND连接提供对背板（框架接地）的访问，从而抑制由屏蔽漏极电流引起的噪声。

在 5 伏直流电下，GE Fanuc IC694ALG390 2 通道模拟输出模块可以处理 32 毫安或 0.16 瓦的负载。在 24 伏直流隔离电压下，IC694ALG390模拟输出模块可以处理 120 毫安或 2.88 瓦的负载。该模块上的 2 个输出通道可以将 13 位数字二进制数据转换为模拟输出信号，用于与之通信的现场设备，并且每次扫描时都会更新。IC694ALG390模拟输出模块的输出电压可以是 -10 到 +10 伏。当IC694ALG390模拟输出模块安装在GE RX3i PacSystem PLC中时，它可以安装在任何可用的I / O插槽中。

GE Fanuc's IC694ALG390 analog output module comes with only 2 output channels, but it can be connected to any CPU manufactured by GE Fanuc in the GE RX3i PacSystem product line. The IC694ALG390 analog output module is also a GE RX3i PacSystem device. The module can be used as an output component in the GE RX3i PacSystem PLC and is installed in the GE RX3i Serial expansion backplane or the GE Series 90-30 expansion backplane. However, this module is not hot-swappable, that is, it cannot be installed on or removed from either type of backplane while it is powered on. Attempting to hot-swap the IC694ALG390 analog output module may cause problems such as damaging the module or backplane, causing the entire PLC to suddenly stop or malfunction, or seriously injuring the user.

The IC694ALG390 is manufactured by GE Fanuc for the Rx3i PacSystem. The IC694ALG390 is a 2-channel analog module with two output channels capable of converting digital data. Channels are updated at an update rate of about 5 milliseconds after each scan. If the CPU resets or goes into stop mode for any reason, the IC694ALG390 module output can be configured to default or left in the last state.

The IC694ALG390 has a voltage range of -10 to +10 volts. The external voltage range is 18VDC to 30VDC, and the external voltage ripple is 10%. The position of the module is important when analyzing the power supply. If the module is located in the RX3i universal backplane, an isolated +24 VDC external power supply is required to provide power to the module. If the module is located in an expansion backplane, its main power supply can be an isolated +24 VDC power supply from the backplane or an external isolated +24 VDC power supply connected to the terminal. If the external power supply is between 27.5-30 VDC, it takes over the load of the module from the isolated 24 VDC system power supply. If the user needs to maintain last-state operation during a backplane power outage, an external power supply should be used.

Field connections should be wired using an appropriate grade of twisted-shielded instrument cable to minimize capacitive load and noise. The shielding should be connected to the GND on the user terminal connector block. The GND connection provides access to the backplane (frame ground), thus suppressing noise caused by the shielded drain current.

At 5 volts DC, the GE Fanuc IC694ALG390 2-channel analog output module can handle loads of 32 mah or 0.16 Watts. At 24 volts DC isolation, the IC694ALG390 analog output module can handle a load of 120 mA or 2.88 Watts. The 2 output channels on the module convert 13-bit digital binary data into an analog output signal for the field devices communicating with it, and are updated with each scan. The output voltage of the IC694ALG390 analog output module can be -10 to +10 volts. When the IC694ALG390 analog output module is installed in a GE RX3i PacSystem PLC, it can be installed in any available I/O slot.
