BTC-704 is a compact 72×72mm analogue temperature controller designed for efficient and space-saving control applications. It features a clear 3.5-digit red LED display, analogue setpoint dial, and deviation alarm relay output. Users can easily select PID or ON/OFF control modes based on process needs. With universal sensor compatibility and reliable performance, this controller is ideal for panel-integrated industrial temperature control systems.
Panel Display and Control Interface
The BTC-704 panel features a 0.5-inch red 3.5-digit LED display, offering clear real-time visibility of process temperatures. An ON (red) LED alarm indicator alerts users when deviation limits are exceeded. The analog potentiometer dial on the front panel allows for precise and intuitive adjustment of the setpoint. This streamlined design ensures simple operation with minimal training and is ideal for panel-integrated control environments.
Input Compatibility and Accuracy
Supports thermocouple and RTD with stable accuracy
BTC-704 supports Type J and K thermocouples as well as 3-wire PT100 RTD sensors (DIN or JIS standards). The input circuit includes cold junction compensation for TC inputs and delivers ±1% of span accuracy, ensuring reliable and accurate temperature measurement across a wide range of applications.
