Mitsubishi R28TB – Precision Analog Input Module for Industrial Systems

Engineered for demanding environments, the Mitsubishi R28TB analog input module delivers consistent signal acquisition in automation setups. Its 8-channel design handles voltage and current signals with minimal drift, making it suitable for real-time monitoring in production lines and facility management systems. We’ve seen this module maintain accuracy even in plants with fluctuating power supplies.

Technical Specifications

Commonly deployed in chemical processing units and assembly lines, this module integrates seamlessly with MELSEC iQ-R Series PLCs. Our clients frequently pair it with temperature sensors in kiln monitoring systems or pressure transducers on hydraulic presses. The IP20-rated enclosure works reliably in factory environments where airborne particulates exist. For similar applications, we often recommend complementary modules like the R28TD or R28TH.

What stands out is the module’s noise-resistant circuitry – in one automotive plant case, it reduced signal interference from nearby welding stations by 40%. The fast conversion time ensures minimal latency in closed-loop control systems, while the wide voltage tolerance prevents downtime during grid fluctuations. Redundant channel design allows continued operation even if one circuit fails, which helped a pharmaceutical client avoid batch contamination during a sensor malfunction.
