Product Details：

Product Dimensions：

The GE Fanuc IC693ALG391B is a 2-Channel Analog Current Output Module designed for the Series 90-30 Programmable Logic Controller (PLC) system. This module provides two high-resolution isolated output channels capable of converting digital data from the PLC CPU into a continuous $4 \text{ to } 20 \text{ mA}$ current signal. It is an essential component for controlling field devices that require a precise current loop to regulate their operation.

Product Parameters

Module Type: Analog Current Output
Backplane Compatibility: Series 90-30 PLC systems
Output Channels: 2 isolated channels
Output Current Range: $4 \text{ to } 20 \text{ mA}$
Resolution: 12-bit binary ( $4 \text{ }\mu\text{A}$ per bit)
Accuracy: Typically $\pm 0.1\%$ of full scale at $25^\circ\text{C}$
Update Rate: Approximately $5 \text{ ms}$ for both channels
Isolation: $1500 \text{V}$ between the field circuitry and the backplane
External Power Requirement: $24 \text{ VDC}$ nominal (typically supplied from the PLC power supply or an external source)
Internal Power Consumption: $25 \text{ mA}$ from the $+5 \text{V}$ bus; $100 \text{ mA}$ from the $+24 \text{V}$ isolated bus
Diagnostics: Status reporting via PLC %I bits and LED indicators

Product Advantages

High Precision and Stability: The 12-bit resolution allows for very fine control of field devices, ensuring that industrial processes remain stable and accurate over time.
Electrical Isolation: The module features robust optical isolation between the sensitive PLC backplane and the external field wiring. This protects the CPU from electrical noise, surges, and ground loops commonly found in industrial environments.
Flexible Power Options: It can utilize the internal isolated $24 \text{ VDC}$ power from the Series 90-30 power supply or an external user-provided $24 \text{ VDC}$ supply, depending on the system load requirements.
Simplified Integration: As a standard Series 90-30 module, it is easily configured using GE's programming software (such as Proficy Machine Edition or VersaPro), requiring minimal manual setup.

Important Considerations and Precautions

External Power Monitoring: If the $24 \text{ VDC}$ power is lost, the module will cease to function correctly. Ensure that the power source is reliable and monitored.
Wiring Polarity: Correct polarity must be observed when connecting the $4 \text{ to } 20 \text{ mA}$ loop. Reversing the leads may prevent the connected device from functioning or lead to incorrect readings.
Shielding and Noise: To minimize electromagnetic interference, it is highly recommended to use shielded twisted-pair cables for the output signals. The shield should be grounded at the module end only.
Load Impedance: Ensure that the total loop resistance (including the field device and wiring) does not exceed the module's maximum drive capability, which is typically $850 \text{ ohms}$ at $24 \text{ VDC}$ .
Hot Swapping Prohibited: Never install or remove this module while the PLC rack is powered on. Doing so can damage the module or the PLC backplane.

Product Applications

The IC693ALG391B is widely used in automation projects where a control signal must be sent from the PLC to a field-level actuator.

Valve Positioning: Controlling the opening and closing of proportional valves in chemical or water treatment plants.
Variable Speed Drives (VSD): Providing a speed reference signal to AC or DC motor drives to regulate conveyor speeds or fan airflow.
Process Heating: Interfacing with power controllers to adjust the output of industrial heaters or furnaces.
Display and Recording: Sending process variables to remote analog chart recorders or large-scale panel meters for operator monitoring.
Signal Re-transmission: Acting as a bridge to send calculated process data from the PLC to other independent control systems or data loggers.
