BTC-704 Compact Analog Temperature Controller

PID or ON/OFF control with LED display & alarm

BTC-704 is a compact 72×72mm analog temperature controller designed for efficient and space-saving control applications. It features a clear 3.5-digit red LED display, analog 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.

BTC-704 Panel Display and Control Interface

Red LED display with analog dial and alarm indicator  

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.  

Output Types and Alarm Function  

Relay, SSR voltage and alarm relay outputs available  

BTC-704 offers a variety of output formats, including relay contact output (5A/240VAC), SSR voltage drive (32VDC / 20mA), and analog current or voltage output (e.g., 4–20mA or 0–10V). A dedicated deviation alarm relay output (2A/240VAC) is also included, providing real-time feedback for critical temperature limits.
