The General Electric IC693ALG391 is a high-performance, 2-channel analog output module designed for the Series 90-30 Programmable Logic Controller (PLC) system. This versatile module provides precise control for industrial processes by offering both current and voltage output signals, making it suitable for a wide range of automation applications.

Features

  • Two independent analog output channels.
  • Supports multiple output ranges: 4-20 mA, 0-20 mA, 1-5 VDC, and 0-5 VDC.
  • High signal integrity with 1500 VAC isolation between field and logic circuitry.
  • Supports external +24 VDC power supply for redundancy and operational stability.
  • Compatible with standard Series 90-30 backplane configurations.

Applications

  • Power grid dispatching systems and remote control units (RTU).
  • Process automation control in chemical and petroleum manufacturing.
  • Motor speed regulation via frequency converters in steel production.
  • Dosing pump flow control in municipal water treatment facilities.

Installation Guidelines

  • Ensure power is disconnected from the PLC rack before inserting or removing the module to prevent electrical damage.
  • The module must be installed in an available slot on the Series 90-30 baseplate.
  • Use twisted, shielded instrumentation cable for all analog signal wiring to minimize electromagnetic interference (EMI).
  • Ground the cable shield at the user terminal connector block to maintain signal integrity.
  • Verify that the external +24 VDC power supply (if used) is within the 20-30 VDC range before connection.

FAQ

What is the primary function of the IC693ALG391?

The IC693ALG391 is an analog output module for the Series 90-30 PLC, used to convert digital data from the CPU into analog current or voltage signals to control field devices.

Does this module require an external power supply?

While it can draw power from the backplane, an external +24 VDC supply can be connected to the terminal board to provide power redundancy and support the "Hold-Last-State" functionality.

What type of cabling is recommended for this module?

To ensure optimal performance and noise rejection, use shielded, twisted-pair instrumentation cabling and ensure the shield is properly grounded at the terminal block.
