FC-TSDI-1624 Temperature Sensing Digital Input Module Industrial Control 16-Channel 24V High Precision

1. High-Density Process Temperature Monitoring​

The Honeywell FC-TSDI-1624 is a 16-channel temperature input module engineered for precision thermal monitoring in industrial automation systems. Featuring ​dual-range universal inputs, this device supports ​thermocouples (Types J/K/T/E/R/S/B/N)​​ and ​RTDs (Pt100/Pt200/Pt1000)​​ with ​​±0.05% accuracy​ and ​24-bit resolution. Its ​compact DIN-rail housing​ provides ​IP40 protection​ while operating across ​​-40°C to +85°C. The "1624" suffix denotes ​16 isolated channels​ and ​24V DC power. Certified for ​SIL 2 compliance​ (IEC 61508), it incorporates ​dual cold junction compensation (CJC) sensors​ with ​​±0.5°C accuracy​ and ​open-wire detection. Integrated ​HART 7.5 communication​ enables digital diagnostics while ​​≤50ms update time​ per channel group ensures real-time process control. Designed for refineries, power plants, and pharmaceutical manufacturing, this module reduces cabinet space by 60% compared to discrete transmitters while providing ​channel-to-channel isolation​ (500V AC) and ​EMC immunity​ >100dB.

​2. Critical Technical Specifications​

This module delivers ​16 individually configurable channels​ with ​0.1µV resolution​ for thermocouples and ​0.01Ω resolution​ for RTDs. Key parameters include ​​±0.05% FS accuracy​ at 25°C, ​​≤1°C CJC drift​ across -40°C to +85°C, and ​4kV surge protection. Electrical isolation reaches ​500V AC channel-to-channel​ and ​1500V AC channel-to-bus. Connection utilizes ​removable screw terminals​ (0.2–2.5mm²) supporting ​2/3/4-wire RTD configurations. Power consumption is ​​≤3.5W​ at 24V DC (±10%) with reverse polarity protection. Environmental resilience includes ​15g shock resistance​ (IEC 60068-2-27), ​5g vibration immunity​ (10–150Hz), and ​​≤95% non-condensing humidity. Certifications: ​CE, ​cULus, ​ATEX/IECEx Zone 2/22​ (Ex ic IIC T80°C Gc), ​IEC 61326-1, and ​FDA 21 CFR Part 11​ (electronic records). Dimensions: ​25×110×75mm​ (W×H×D) with ​500,000h MTBF​ at 40°C.

​3. Industrial Process Applications​

This module excels in critical temperature monitoring scenarios:

• ​Distillation Columns: Multi-zone temperature profiling in refineries
• ​Power Generation: Turbine bearing RTD monitoring (API 670)
• ​Chemical Reactors: Exothermic reaction control with Type K thermocouples
• ​Pharmaceutical: Lyophilizer shelf temperature mapping (GMP compliance)
• ​Food Processing: Retort sterilization validation
• ​HVAC Systems: Duct temperature gradient analysis
• ​Semiconductor: CVD chamber wall thermocouples
• ​Metal Processing: Annealing oven control
  Its dual-range capability eliminates external signal conditioners by directly accepting thermocouples and RTDs in the same module. The 16-channel density enables comprehensive thermal mapping in large-scale equipment like cracking furnaces or extrusion lines, while SIL 2 certification supports deployment in safety instrumented systems (SIS) for over-temperature protection per IEC 61511 standards. HART communication allows remote calibration and drift monitoring without process interruption.
