ATK4A-00

The Yokogawa ATK4A-00 is a signal converter designed for temperature sensors (RTD or thermocouple). It converts the sensor signal into a stable and isolated 4-20 mA analog output for reliable transmission to control systems. This compact and robust module is suitable for DIN rail mounting and is widely used in industrial automation and process control applications.
