Product Overview

The GE IC693ALG391F is a 2-channel analog current output module for the Series 90-30 PLC platform. It converts digital control values from the CPU into precise 4–20 mA signals for driving field devices such as valve positioners, VFDs, and process instrumentation. Designed for closed-loop control applications, this module ensures stable and accurate signal delivery. We supply this unit as 100% brand new, original condition for reliable industrial performance.

Technical Specifications

Engineering Advantages

High-Precision Signal Scaling
12-bit resolution enables fine 4 µA adjustments, supporting precise control of valves and actuators in tightly regulated processes.

Robust Load Drive
Supports up to 850 Ω load impedance, maintaining signal integrity over long cable distances in industrial environments.

Rapid Response Time
5 ms update rate ensures fast signal response, improving PID loop stability and overall process control performance.

Diagnostic Feedback
Monitors external 24 VDC loop power and reports fault conditions to the CPU for safe-state response or alarm handling.

FAQs

What does the “F” suffix mean?
It indicates a hardware revision with updated internal components while maintaining full backward compatibility with earlier versions.

Does this module require external power?
Yes. A 24 VDC external supply is required for loop power, while logic power is drawn from the backplane.

What happens if the CPU stops communicating?
The module can be configured to hold last value or default to a safe output level to prevent unsafe process behavior.

Can it output 0–10 V signals?
No. This module is designed for 4–20 mA current output only. A voltage output module is required for 0–10 V applications.
