IC694ALG233 是一款具有 3 个单端输入通道的 PACSystems RX16i 模拟电流输入模块。 每个输入均可使用配置软件针对三个输入范围进行配置：4 至 20 mA、0 至 20 mA 和 4 至 20 mA 增强型。

三个范围提供高限和低报警限值。对于 4 至 20 mA 增强型范围，可以启动低报警限值以检测 4 mA 至 0 mA 的输入电流;这可在 4 至 20 mA 增强型应用中提供开路故障检测。此外，IC694ALG233通过其分配的程序参考地址向CPU报告模块状态和外部电源状态。IC694ALG233必须安装在 RX3i 系统中带有串行连接器的 I/O 插槽中。

IC694ALG233模块可通过软件配置，无需设置模块跳线。所有输入的开路检测均提供 4 至 20 mA 增强范围。可配置的缩放和偏移以及故障报告是其他有用的功能。该模块支持逻辑程序中的诊断点故障触点，并支持固件升级。包括正负变化率警报以及模块序列号/修订/日期代码显示。该模块还支持热插入/拔出。

模块状态可通过发光 LED 轻松确定，如下所示。ON 表示正常，模块配置正确。OFF 表示没有底板电源，或者软件可能未运行。如果 LED 发出连续快速闪烁，则存在配置数据问题。缓慢闪烁后熄灭表示遇到通电诊断失败问题或代码执行错误。用户电源 LED 确定外部 24 VDC 电源是否合适。

IC16ALG694输入模块共有 233 个通道，每个通道可配置以下输入范围：0 至 20 毫安、增强型 4 至 20 毫安和正常 4 至 20 毫安。报警上限和下限也可以通过软件进行配置。对于 4 至 20 毫安的增强电流范围，可以配置一个低报警限值，以检测 4 至 20 毫安之间的输入电流。此功能可用于在 4 至 20 毫安的增强型额定电流应用中提供开路检测。IC694ALG233输入模块还使用分配的程序参考地址向系统 CPU 报告模块状态和外部电源状态。IC694ALG233输入模块可以安装在串行连接器附带的 I/O 插槽中。IC694ALG233输入模块支持热拔出和插入。IC694ALG233输入模块上的固件可以升级以启用新功能。

【英文介绍】

Module type: Analog current input

Number of inputs: 16 single-ended

Internal power supply: +5V: 120 MA

Number of slots: 1 (single slot)

Current range: 0-20 MA, 4-20 MA, 4-20 MA (enhanced)

Backplane support: No backplane limit

The IC694ALG233 is a PACSystems RX16i analog current input module with three single-ended input channels. Each input can be configured using configuration software for three input ranges: 4 to 20 mA, 0 to 20 mA, and 4 to 20 mA Enhanced.

Three ranges provide high and low alarm limits. For the 4 to 20 mA enhanced range, low alarm limits can be activated to detect input currents from 4 mA to 0 mA; This provides open circuit fault detection in 4 to 20 mA enhanced applications. In addition, the IC694ALG233 reports module status and external power status to the CPU through its assigned program reference address. IC694ALG233 must be installed in the I/O slot with serial connector in the RX3i system.

The IC694ALG233 module can be configured using software. No jumper is required. Open circuit detection for all inputs is available in an enhanced range of 4 to 20 mA. Configurable scaling and offset and fault reporting are other useful features. The module supports diagnostic fault contacts in logic programs and supports firmware upgrades. Includes positive and negative rate of change alerts and module serial number/revision/date code displays. The module also supports hot insertion/removal.

The module status can be easily determined by an illuminated LED, as shown below. ON indicates that the module is correctly configured. OFF indicates that there is no baseboard power supply, or the software may not be running. If the LED flashes continuously and rapidly, there is a configuration data problem. Blinking slowly and then off indicates a power-on diagnosis failure or code execution error. User Power LED Determines if external 24 VDC power supply is appropriate.

The IC16ALG694 input module has 233 channels, each of which can be configured with the following input ranges: 0 to 20 mah, enhanced 4 to 20 mah, and normal 4 to 20 mah. The upper and lower alarm limits can also be configured via software. For an enhanced current range of 4 to 20 mA, a low alarm limit can be configured to detect input currents between 4 and 20 mA. This function can be used to provide open circuit detection in enhanced current rating applications ranging from 4 to 20 mA. The IC694ALG233 input module also reports the module status and external power supply status to the system CPU using the assigned program reference address. The IC694ALG233 input module can be installed in the I/O slot that comes with the serial connector. The IC694ALG233 input module supports hot removal and insertion. The firmware on the IC694ALG233 input module can be upgraded to enable new features.
