Description

The HITACHI LYA210A Analog Input Module operates with a 10 to 30 V DC power supply, which powers the module while maintaining a maximum supply current of 10 mA.

It measures temperatures from -200°C to +1600°C with a resolution of 0.01°C.

The Hitachi LYA210A is a high-performance, 8-channel thermocouple analog input module tailored for Hitachi’s H-Series industrial automation ecosystem, engineered to capture, condition, and convert temperature data from thermocouples into reliable digital signals for precision control and monitoring in harsh industrial settings.

As a specialized extension of Hitachi’s modular I/O lineup, it addresses the critical need for accurate, real-time temperature measurement across sectors like chemical processing, metalworking, power generation, and semiconductor manufacturing—where thermal stability directly impacts product quality, process safety, and operational efficiency.

The LYA210A features 8 isolated thermocouple input channels, each optimized for direct connection to industry-standard thermocouple types including J, K, T, E, R, S, B, and N, with built-in cold-junction compensation (CJC) for consistent accuracy across ambient temperature fluctuations.

This eliminates the need for external signal conditioners, reducing system complexity and potential points of failure.

Each channel delivers 16-bit conversion resolution and ±0.1% of Full Scale (F.S.) accuracy (with linearity error ≤±0.05% F.S.), ensuring precise temperature readings even in high-noise industrial environments where millivolt-level signals demand exceptional signal integrity.
