The Applications
1. Protecting Flow Sensors in Chemical Processing Plants
In chemical production facilities, 4–20 mA flow transmitters are often installed far from control rooms, leaving long cable runs exposed to electrical interference and lightning surges. The TTC-6P-1X2-F-M-24DC-PT-I helps isolate and absorb these transient voltages before they damage the sensors or disrupt measurement accuracy. Its ultra-fast response time and combined line-to-line and line-to-ground protection design ensure the signal remains stable. With its slim 6 mm profile, multiple protection channels can fit easily into dense control cabinets without needing extra space.
2. Reliable Temperature Monitoring in Oil and Gas Sites
Oil and gas plants operate in hazardous environments where temperature probes and transmitters are part of safety-related control loops. This surge protection module provides reliable isolation between safe and hazardous areas, preventing high-energy transients from crossing zones. The durable housing, broad operating temperature range, and compliance with SIL 3 standards make it suitable for mission-critical installations. By preventing unwanted surge energy from reaching sensors, it safeguards both equipment and personnel while maintaining accurate process data.
3. Stable Level Control in Water Treatment Systems
Water treatment plants rely on accurate tank-level transmitters and sensors distributed across large areas. These long signal cables often run near pumps or variable-speed drives, exposing them to electrical noise and surges. Installing the TTC module at the signal input protects against interference, keeping control signals precise and uninterrupted. The integrated optical indicator allows quick visual confirmation of protection status, reducing unnecessary maintenance and ensuring continuous monitoring of water levels with minimal downtime.
4. Protecting Wind Farm SCADA Signal Lines
Wind turbines and weather monitoring systems in wind farms are connected by long sensor cables that face strong electromagnetic fields and lightning exposure. This compact surge protection module prevents damage to SCADA communication interfaces by quickly redirecting surge energy to ground. Its tool-free plug-in design simplifies maintenance, allowing replacement without shutting down systems. The combination of fast reaction time, compact housing, and easy installation makes it an excellent choice for renewable energy control systems.
