📦 Product Overview: FS‑TRO‑1024
The FS‑TRO‑1024 is a thermal resistance / temperature input module designed for industrial process control systems. It accepts RTD (resistance temperature detector) or thermistor inputs and converts them into standardized signals for monitoring or control purposes. This module is built to reliably handle temperature sensing across multiple channels, serving as a bridge between field temperature sensors and higher‑level control or automation systems.
Engineered for performance and longevity, the FS‑TRO‑1024 includes signal conditioning, linearization, and noise rejection circuitry to ensure accurate temperature readings in electrically noisy industrial environments. Its modular design supports integration into control cabinets and DIN‑rail systems.
🧰 Applications
-
Multi‑channel temperature measurement in process plants
-
Integration into SCADA, DCS, or PLC systems for thermal control
-
Monitoring of heaters, chillers, ovens, and reactors
-
HVAC systems temperature sensing
-
Food, pharmaceutical, and chemical processing lines
-
Energy systems (boilers, turbines, heat exchangers)
-
Environment control in cleanrooms, labs, and industrial facilities
⭐ Key Advantages
-
Multi‑channel support: Can handle multiple RTD or thermistor inputs in one module
-
Signal conditioning & linearization: Accurate conversion and compensation for non‑linear sensor behavior
-
Noise immunity: Designed with filtering and shielding to reject electrical interference
-
Compact & modular: Fits standard DIN‑rail or panel mounting layouts
-
Wide input range: Supports common RTD types (e.g., Pt100, Pt1000) and thermistors
-
Reliable performance: Stable over time, minimal drift, and robust design
-
Easy integration: Compatible with control systems, easy wiring, and modular expansion
