IC694ALG223 High density analog input module Ability to report open circuit fault detection

The IC694ALG223 is an RX3i Programmable Automation Controller (PAC) high-density analog input module formerly manufactured by GE Fanuc and now owned by Emerson Automation. The module has sixteen (16) single-ended analog input channels that can be individually configured to accept 0-20 mA; 4-20 mA (standard) and 4-20 mA (enhanced) input signals with a resolution of 12 bits and a conversion rate of 13 ms.
The IC694ALG223 is a high-density analog input module. The module is designed with sixteen (16) single-ended input channels that are compatible and configurable for 0-20 mA, 4-20 mA (normal), and 4-20 mA (enhanced) analog signals. The module occupies a single slot in any PACSystems RX3i chassis and can be used as a local or distributed I/O module for the Rx3i and RX7i controller platforms. The module is primarily used to connect measurement and signal instruments.

Such as transmitters, sensors, isolators and similar devices. It allows the integration of received analog data by converting it to a digital equivalent. This is done via an embedded analog-to-digital converter (ADC), where each channel is available individually and the conversion resolution is 12 bits. In addition, the update rate is 13 ms per channel and factory calibration is 4 μA per count in the range of 4 to 20 mA; The 0 to 20 mA and 4 to 20 mA intensifiers count 5 μA each time. For 4-20 mA configurations, the resolution is 4 μA (4 μA/bit) : for 0-20 mA and 4-20 mA, the resolution is 5 μA (5 μA/bit).

The IC694ALG223 has configurable alarm Settings that can be configured using control software. In addition, when configured at 4-20 mA inputs, the module is also capable of reporting open circuit fault detection. In addition, the module provides state feedback about the operation of the external power supply, which can be integrated into a specific program reference address in the CPU.

The IC694ALG223 has an internal current consumption of 120 mA from a 5VDC bus voltage and 65 mA, including individual current from each current loop powered by an external 24 VDC supply voltage.

The IC694ALG223 input module is a 16-channel analog current input module from the GE Fanuc and RX3i PacSystems series. The IC694ALG223 input module has 16 single-ended input channels. The configuration software allows you to configure three input ranges for each input channel, which are 0 to 20 mah, 4 to 20 mah (enhanced), and 4 to 20 mah (normal). High and low alarm thresholds can be set for all input ranges. For enhanced input ranges from 4 to 20 mA, alarms can be set to detect input currents from 4 to 0 mA, providing open circuit fault detection for rated applications from 4 to 20 mA. The IC694ALG223 input module can update the power status and module status of the system CPU. The IC694ALG223 input module can be installed in the I/O slot of Series 90-30 PLC systems with serial connectors.
