Product Introduction
LIC1075/11 EMG is a specialized electronic line filter board engineered by EMG Automation for heavy-duty metal processing and strip guiding systems. This module suppresses high-frequency electrical noise and conditions incoming control signals, ensuring stable operation of electro-hydraulic actuators in steel, aluminum, and continuous processing lines.
The board interfaces directly with EMG control racks and sensor systems (such as inductive edge sensors and optical strip center measuring devices). Its robust circuit layout isolates sensitive processing loops from electromagnetic interference generated by adjacent variable frequency drives and high-power industrial equipment.
Frequently Asked Questions
Q: Are these modules factory-new or surplus, and how do you test them? A: Because OEM production for legacy EMG modules is limited or discontinued, available inventory is sourced from verified new surplus or decommissioned strip guiding panels. Every LIC1075/11 EMG undergoes a strict 5-step SOP validation before dispatch:
- Inbound Inspection: Verification of customs/origin documentation, serial number checks, visual inspection for trace oxidation, and terminal contact check.
- Live Functional Testing: Installed on a dedicated simulation rack to test signal pass-through, line noise attenuation, and communication stability over a 24-hr load run.
- Electrical Testing: Insulation resistance testing using a 500 V Megger (>10 MΩ target) and grounding continuity checks across filter ground paths.
- Hardware Verification: Recording factory revision codes and checking passive circuit components.
- Final QC & Packaging: Sealed in anti-static shielding bags, cushioned with heavy bubble wrap, and labeled with a physical QC Passed tag.
Q: Can I hot-swap the LIC1075/11 EMG while the strip guiding line is running? A: No, you should never attempt to hot-swap this filter module while the line is energized. Removing or inserting circuit cards under power causes voltage transients that can disrupt active hydraulic servo valves or corrupt controller sensor feedback, risking a strip alignment fault. Always disconnect main panel control power before replacing the module.
Q: What technical pitfalls should field engineers avoid during replacement? A: In our field service experience, engineers encounter five critical mistakes during replacement:
