Key Features
High Accuracy and Stability: Provides precise signal conversion with minimal drift over time and temperature changes.

Excellent Noise Immunity: 1500 VAC isolation effectively breaks ground loops and suppresses noise interference.

Compact DIN Rail Mounting: Saves space in control panels and allows for high-density installations alongside other components.

Easy Maintenance: The plug-in design with a removable terminal block allows for quick replacement without rewiring, reducing maintenance time.

High Reliability: Built with industrial-grade components for long-term operation in harsh environments.
