BTC-404 Compact PID Process Controller
1/4 DIN size, universal input, and stable control
The BTC-404 is a panel-mount fuzzy PID controller that delivers reliable temperature and process control in a compact 1/4 DIN (96×96 mm) format. It supports thermocouple (J/K) and RTD (PT100) inputs and offers ON/OFF or time-proportional control. With features such as deviation alarm, high-visibility LED display, and selectable output types (relay, SSR, or analog), this controller is ideal for integration into industrial heating, cooling, and automation systems.
BTC-404 Panel Interface and Display
Clear LED display and intuitive indicator lamps
The BTC-404 features a 0.5-inch red 3-1/2 digit LED display, providing excellent readability of process values even in low-light industrial settings. The panel includes ON (red) LED lamps to indicate output status and alarm conditions, helping operators monitor real-time operation at a glance. A precise analog dial knob allows smooth adjustment of the control setpoint, ensuring accuracy and convenience during parameter setup. Designed with simplicity and reliability in mind, the BTC-404 panel interface reduces operator error and supports quick configuration without complex menus or programming steps. This design makes it ideal for OEM and system-integrated temperature control environments.
Wide Compatibility
Thermocouple and RTD support with high accuracy
BTC-404 supports Type J and K thermocouples as well as 3-wire PT100 RTDs (DIN or JIS standard). The input system features ±1% of span accuracy and cold junction compensation for thermocouples. It also includes upscale detection for sensor break and excellent noise immunity, ensuring stable performance in challenging industrial environments.
Flexible Control Choices
Relay, SSR drive, analog and alarm outputs
BTC-404 提供多樣控制輸出方式，包含：
-
繼電器輸出（5A/240VAC）
-
固態繼電器（SSR）驅動電壓輸出（32VDC / 20mA）
-
類比輸出：0–10VDC、0–20mA 或 4–20mA（最大負載 500Ω）
-
偏差設定用警報繼電器輸出（2A/240VAC）
這些輸出選項可靈活搭配各類製程設備與控制系統，滿足不同應用需求。
