Product System Function Introduction
1. Applicable SystemIf you’re using HONEYWELL Experion PKS DCS, this module is a must-have—it’s specifically designed for this series. It’s mainly used in industrial process control systems that require high-precision analog signal collection, like those in chemical or power plants.Q: What other modules can it work with in the Experion PKS system? A: Quite a few common ones, let me list the most frequently used:
- LG1094AC01 (Analog Output Module)
- LG1081AC01 (Digital I/O Module)
- LG1201AC01 (Power Supply Module)
- LG1501AC01 (Communication Module)
It’s built for harsh industrial environments, not ordinary office settings—so it’s durable enough to handle long-term operation.
2. System Role
To be honest, this module is like the “eyes” of the Experion PKS system. It collects analog signals from field sensors—things like temperature, pressure, and flow—and sends them to the CPU module for analysis.Without it, the system would be blind. It doesn’t just collect signals; it also filters out interference to ensure data accuracy—way more reliable than some cheap alternative modules. You might ask, why not use a universal module? Because it’s tailored for Experion PKS, so compatibility is 100% and there’s no risk of signal loss.3. Working PrincipleThe working principle is straightforward, but there’s one point to note: it uses 24VDC power supply, which is more stable for industrial sites than AC power. Let’s break it down step by step:
- First, it connects to field analog sensors via signal lines.
- Then, it receives 4-20mA analog signals from these sensors and converts them into digital signals.
- Finally, it transmits the converted digital signals to the Experion PKS CPU via the system bus.
It also has built-in self-detection—if there’s a signal fault, it will alert the system immediately… no need for manual checks all the time.

Physical Parameters (Size & Weight)
Honestly, this module is designed to save space. Unlike some bulky modules that take up half the rack, this one is compact and fits perfectly in the Experion PKS standard rack. Here are the key physical details:
- Dimensions: 82mm × 120mm × 148mm (about the size of a small book)
- Weight: Approximately 0.85kg (light enough to install with one hand)
- Mounting: Experion PKS standard rack mounting (no extra adapters needed)
- Enclosure Material: High-strength industrial aluminum alloy (tough, not easy to damage)
- Protection Level: IP20 (cabinet mounting, dust-proof and anti-collision)
- Indicator Lights: LED indicators (power, operation, fault—easy to check at a glance)
Technical Specifications
Let’s talk tech specs—no fancy jargon, just what you need to know. The module runs on 24VDC ±10% voltage, so it can handle small power fluctuations (super common in factories).It has 8 analog input channels, each supporting 4-20mA signals—the most common industrial standard, so it works with almost all analog sensors. A few more key points:
- Operating temperature: -20℃ ~ 65℃ (works in both cold and hot workshops)
- Response time: ≤3ms (fast enough for real-time control)
- Isolation: Photoelectric isolation between channels (avoids signal interference)
- Compatibility: Fully compatible with all Experion PKS DCS modules
It’s designed for reliability, not flash—after all, industrial control relies on stability, not fancy features.
Application Industries
It’s used in many industries, but these are the main ones where it shines:
- Chemical Industry: Reactor temperature, pressure signal collection (critical for safe production)
- Power Industry: Thermal power plant boiler, turbine parameter monitoring
- Oil & Gas Industry: Refinery flow, pressure signal acquisition
- Pharmaceutical Industry: Production process analog signal control
For example, in a chemical plant, this module collects the temperature signal of the reactor and sends it to the control system—if the temperature is too high, the system will trigger an alarm immediately, preventing accidents.
Usage Instructions
Using this module isn’t hard, but there are a few mistakes people often make—let me remind you:
- Installation: Mount it on the Experion PKS standard rack, make sure the connection is firm—loose connections cause signal distortion.
- Wiring: Use shielded cables for signal lines, separate power and signal lines—this prevents interference (trust me, I’ve seen many faults caused by wrong wiring).
- Configuration: Set the channel parameters via Experion PKS configuration software—don’t skip this, or the module won’t collect signals correctly.
Q: Do I need to cut off power during maintenance? A: Definitely! Never touch the module or wiring without cutting off power—it’s for your safety and the module’s. Also, clean the surface dust regularly; too much dust can cause overheating.
