SCN-2-11+ is a professional-grade industrial signal converter & isolator, designed to convert, isolate, and amplify industrial process signals (e.g., current, voltage, thermocouple, RTD) for stable data transmission between measuring instruments, controllers, and PLC/DCS systems. Its core functions and typical applications are detailed below.
- Signal Conversion: Converts between common industrial signals, including 4-20mA DC current ↔ 0-10V DC voltage, thermocouple (J/K/T/E/R/S/B) ↔ 4-20mA, and RTD (Pt100/Pt1000) ↔ 0-5V, adapting to different equipment interface requirements.
- Electrical Isolation: Provides 2500V AC/DC galvanic isolation between input, output, and power supply. It suppresses electromagnetic interference (EMI) and ground loop noise, protecting sensitive components from voltage spikes.
- Signal Amplification & Stabilization: Amplifies weak signals (e.g., millivolt-level thermocouple signals) to standard 4-20mA/0-10V signals. It maintains signal stability even in harsh industrial environments with voltage fluctuations.
- Wide Power Supply Range: Supports universal power input (e.g., 12-36V DC or 85-265V AC), enabling flexible installation in various industrial power systems without additional power adapters.
- Reverse Polarity Protection: Equipped with input/output power reverse polarity protection to prevent device damage caused by incorrect wiring during installation.
- Industrial Automation Systems: Used in factory production lines to connect sensors (pressure, temperature, flow sensors) with PLC/DCS systems. It resolves signal incompatibility issues between different devices.
- Process Control Environments: Deployed in chemical plants, oil refineries, and pharmaceutical facilities. It isolates and converts signals from on-site sensors to ensure reliable data transmission in high-interference environments.
- Building Automation: Applied in HVAC systems, smart buildings, and energy management systems. It converts temperature/humidity sensor signals to standard formats for integration with central control panels.
- Instrumentation Upgrades: Facilitates the connection of old analog instruments (with 0-5V output) to new digital control systems (supporting 4-20mA input), avoiding costly replacement of existing equipment.
- Test & Measurement Systems: Used in laboratories and test benches to convert and isolate signals from various sensors, ensuring accurate data acquisition without interference from external electrical noise.
