Description
GE Fanuc 8106-TI-RT High-Precision RTD Input Module
The 8106-TI-RT is a 4-channel RTD input module designed for GE Fanuc PACSystems RX3i platforms, specializing in industrial temperature measurement and control. Engineered for reliability in harsh environments, this module supports 2-, 3-, or 4-wire RTD sensors (e.g., PT100, Ni120) with 15-bit resolution and ±0.1% accuracy, ensuring precise data acquisition for critical processes like chemical reactors, power plant turbines, and food processing lines. Its hot-swap capability and -40°C to +85°C temperature tolerance make it ideal for 24/7 operations in extreme conditions.
