Product Overview

The IC694ALG442 is a mixed analog module for the GE PACSystems RX3i platform, offering four analog input channels and two analog output channels in a single slot. It supports a variety of industrial signals, including unipolar/bipolar voltage and 0-20 mA / 4-20 mA current loops. This module is 100% brand new, ensuring peak performance in your RX3i or Series 90-30 systems.

Technical Specifications

Engineering Advantages

• Consolidated I/O Architecture:
  Combines four inputs and two outputs in a single slot, saving rack space and reducing overall hardware costs. Ideal for compact PID control loops.

• Flexible Signal Interfacing:
  Channels are independently configurable, allowing you to monitor sensors and control actuators (e.g., modulating valves, variable frequency drives) with the same module.

• Programmable Fail-Safe States:
  Configurable output behavior during CPU stops or communication failure. Choose between "Hold Last State" to maintain the current process or "Downscale" to drive the output to its minimum value.

• Universal Backplane Support:
  Compatible with RX3i universal backplanes, Series 90-30, and RX7i systems, ensuring protection for your hardware investment when migrating to new platforms.

FAQs

Does this module require an external power supply?

It draws power from the backplane, but you may need external 24 VDC for field devices connected to the module.

How do I configure the input and output ranges?

Use Proficy Machine Edition software for signal scaling and range selection—no physical jumpers or switches are required.

Can I use this module in a Series 90-30 expansion rack?

Yes, it is compatible with Series 90-30 expansion and remote baseplates.

What is the difference between "Hold" and "Downscale" modes?

"Hold" keeps the current output signal, while "Downscale" drops the output to the lowest value, typically used to trigger safety positions for valves.
