Mitsubishi R28TB Temperature Input Module – Precision Control for Demanding Environments
Engineered for industrial environments where temperature accuracy makes or breaks production quality. The R28TB handles 8 thermocouple channels simultaneously while maintaining ±0.3% measurement precision – critical for processes like heat treatment furnaces or polymer curing ovens. Its 14-bit resolution captures subtle temperature fluctuations that lesser modules would miss.

Real-World Applications
We’ve supplied R28TB modules for diverse applications – from monitoring blast furnace temperatures in steel mills to maintaining precise cryogenic storage conditions in pharmaceutical warehouses. Clients in the beverage industry particularly appreciate its stability during fermentation processes where ±1°C variations directly impact product consistency.
When paired with Mitsubishi’s Q64RD temperature control CPU, this module forms the backbone of systems maintaining critical processes in chemical reactors and semiconductor manufacturing lines. We also commonly integrate it with Allen Bradley 1756-IT6I modules in hybrid control cabinets for automotive paint shops requiring multi-vendor compatibility.
Our Commitment to Support
Every R28TB purchase includes our standard 12-month warranty covering both parts and labor. With 16 regional warehouses across 6 countries, we typically achieve 48-hour delivery for in-stock units. For urgent requirements, our technical team can often source refurbished units with full testing reports available within 24 hours.
Email us or WhatsApp for current pricing – we match or beat competitors’ quotes for identical configurations. Our engineers also provide free pre-installation consultation to ensure seamless integration with existing control systems.
“Personally, I’ve noticed this module performs exceptionally well in high-humidity environments compared to similar units – our paper mill client in Indonesia hasn’t had a single calibration issue in 18 months.”
