ICS TRIPLEX 8106-TI-RT 4-Channel RTD Input Module

8106-TI-RT is a 4-channel RTD temperature acquisition module for ICS TRIPLEX PAC8000 / 8000 I/O control system. It supports 2/3/4-wire Pt100, Ni120 and other thermal resistance sensors, converting resistance signals into standardized digital data uploaded to the main controller via Railbus backplane. Built-in 250VAC isolation suppresses industrial electromagnetic interference and ground loop drift, ensuring stable temperature measurement in chemical, power and oil & gas sites.

This discontinued temperature I/O module is a mainstream maintenance spare for legacy process control systems. It adopts conformal-coated PCB for anti-corrosion, supports hot-swap replacement without full system shutdown, and is equipped with front panel LED indicators to quickly detect open-circuit, over-range and power supply faults during field debugging.

Core Functions

• Collect real-time temperature signals from field RTD sensors, convert resistance variation into digital temperature values for PLC processing and monitoring.
• Multi-stage digital filtering is optional to filter high-frequency noise, avoiding measurement jitter caused by high-power equipment in industrial workshops.
• Independent isolation design for each channel prevents single-channel wire breakage or overload faults from affecting other temperature measurement loops.
• Built-in open-circuit self-diagnosis function automatically triggers alarm signals when sensor cables fall off or break, eliminating blind measurement risks.
• Hot-swappable modular structure allows independent module replacement without shutting down the whole control rack, reducing downtime of continuous production lines.
• Standard Railbus communication bus transmits temperature data to the main controller synchronously, supporting real-time trend recording and over-temperature interlock logic.
