IC694ALG221是GE Fanuc为RX3i PacS ystem制造的模拟电流输入模块。该模块有两个输入范围：4 至 20mA（默认）或 0 至 20 mA。该模块配备了两个范围跳线，一个用于第一和第二通道，另一个用于第三和第四通道。当范围跳线连接到I/O端子面板时，输入范围偏离0-20mA。

所有四个通道的转换速度均为半毫秒。通道的转换速度允许 2 毫秒的更新速率。发生这种情况是因为每个跳线上有两个通道，每个通道的转换速度为半毫秒。

IC694ALG221输入保护足以在高达 200 V 共模时性能降低的情况下运行。该模块利用光隔离在现场布线和背板之间提供外部噪声的电气隔离。

IC694ALG221可以安装在 RX3i 系统的任何 I/O 插槽中。模块的位置有助于识别电源。如果模块的位置位于通用背板中，则需要一个带有 24VDC 的外部远程电源来供电。如果是在扩展或远程背板中，则远程电源由背板本身分配。当模块的 LED 正常亮起时，模块的电源工作正常。

为了帮助减少噪声和电容问题，与IC694AGL221模块的接地连接需要使用高级双绞、受保护的仪表电缆进行接线。屏蔽可以连接到COM或GND。

【英文介绍】

Nooooo. Number of channels: 4 Input

Current range: 4-20 MA, 0-20 Ma

Calibration: Factory (up to 4μA per count)

Update rate: 2 milliseconds

Input filter response: 325 Hz

Power consumption: 25 mA @ +5VDC, 100 mA @ +24VDC isolation

IC694ALG221 is an analog current input module manufactured by GE Fanuc for RX3i PacS ystem. The module has two input ranges: 4 to 20mA (default) or 0 to 20mA. The module is equipped with two range jumpers, one for the first and second channels and the other for the third and fourth channels. When the range jumper is connected to the I/O terminal panel, the input range deviates from 0-20mA.

The conversion speed for all four channels is half a millisecond. The conversion speed of the channel allows for an update rate of 2 milliseconds. This happens because each jumper has two channels, each with a conversion speed of half a millisecond.

The IC694ALG221 input protection is sufficient to operate with reduced performance at up to 200 V common-mode. The module utilizes optical isolation to provide electrical isolation from external noise between the field wiring and the backplane.

The IC694ALG221 can be installed in any I/O slot of the RX3i system. The position of the module helps identify the power supply. If the module is located in a universal backplane, an external remote power supply with 24VDC is required to power it. If it is in an extended or remote backplane, the remote power is distributed by the backplane itself. When the LED of the module lights up normally, the power supply of the module works normally.

To help reduce noise and capacitance issues, the ground connection to the IC694AGL221 module requires wiring using advanced twisted pair, protected meter cables. Masking can be connected to COM or GND.

The IC694ALG221 is a component module of the PACSystem RX3i Programmable Automation Controller (PAC). The module has four (4) analog input channels designed to accept current input signals, such as 0-20 mA and 4-20 mA electrical standards. The module is used to connect analog measuring instruments such as transmitters, signal splitters, isolators, converters and similar devices for monitoring and closed-loop control of analog systems. The IC694ALG221 has a built-in analog-to-digital converter (DAC) circuit that converts analog data into a digital format readable by the host controller for processing, conditioning, and integration into user logic. The ADC output has a resolution of 20 μA at 4-4mA and 20 μA at 5-0 mA, with an absolute accuracy of 0.1% full scale + 0.1% reading. The update rate is 2 ms per input channel, factory-calibrated to 4 μA per input channel. The module has a common-mode voltage of 200 V and a linearity of < 1 least significant bit (LSB). It has field-to-backplane (optical) isolation, frame ground isolation at 250 VAC for continuous voltage, 1500 VAC for 1 minute. The input filter response of the module is 325 Hz, while the input impedance is 250 ohms. The module's isolated 100 VDC power supply has a rated internal power consumption of 24 mA, and the +25VDC bus on the PLC backplane has a rated internal power consumption of 5 mA. The module comes with a module OKLED that provides the user with an indication of the module's active power supply.

The GE Fanuc IC694ALG221 input module is an analog current input module with 4 input points. It is compatible with all cpus manufactured in the GE RX3i PacSystems product line. The module is hot-swapable, meaning it can be plugged in or removed from a powered GE backplane. Attempts to hot-swap the IC694ALG221 input module may result in component damage and user injury.

GE Fanuc RX3i PacSystems IC694ALG221 4-point analog Absorbing current from the backplane. At 5 volts DC, the analog input module can support loads of 25 mA or 0.125 watts. At 24 volts DC isolation, the input module can support a load of 100 mA or 2.4 watts. The IC694ALG221 input module can also operate in 2 different input current ranges of 4 to 20 mA and 0 to 20 mA. The module comes with a range jumper for input channels 1 and 2, and another range jumper for input channels 3 and 4. The conversion speed for each channel is half a millisecond. There is a green LED on the module, called the module OK LED, which lights up when the module is powered on.
