LED 顯示與 4 鍵簡約型面板操作介面
雙排顯示搭配直覺式按鍵,設定更快速便利
BTC-9090 採用精巧的 48×48mm 面板設計,搭配清晰的 雙排 4 位數 LED 顯示器,上排顯示製程值(PV),下排顯示設定值(SV),方便操作時快速參考與確認狀態。
面板配備 四顆觸感式按鍵:
-
上/下鍵 用於數值增減
-
SCROLL 鍵 進行參數瀏覽切換
-
RETURN/ENTER 鍵 用於確認與返回操作
按鍵配置直覺清楚,搭配高亮度顯示器,即使在狹小或光線不足的場域也能快速完成設定與調整,提升整體操作效率與穩定性。
Universal Input for T/C, RTD, mV & Voltage
High-accuracy A/D with wide signal compatibility
BTC-9090 accepts a broad range of universal input types, including:
-
熱電偶: J, K, T, E, N, R, S
-
RTD: Pt100 DIN / JIS
-
Linear: 0–50 mV, 0–5 V, 1–5 V
The unit uses a high-resolution 18-bit A/D converter with a sampling rate of 3Hz, delivering stable readings and precise process control. Cold junction compensation and digital filtering ensure input signal integrity even under industrial conditions.
多樣化輸出選項,滿足各種控制需求
可選擇繼電器、SSR 或高精度類比輸出
The controller offers multiple output options for control and alarm use:
-
Relay contact: 250 VAC / 2A
-
SSR voltage drive: 12 VDC ±15%, 30 mA max
-
Analog output: 0–20 mA, 4–20 mA, 0–10 V, 1–5 V
Analog outputs are generated via a 15-bit D/A converter, ensuring high-resolution retransmission and smooth signal control. Each output channel can be independently configured for PID control, alarm logic, or dwell timer functions, providing great flexibility in system integration.
Fuzzy(模糊邏輯) PID 控制技術
聰明穩定又快速,讓控制更勝一籌
模糊邏輯與傳統 PID 控制結合,實現更智慧且具適應性的溫度調節功能。
相較於傳統 PID 控制器需針對每個應用手動微調參數,模糊 PID 能根據實際製程變化即時動態調整控制反應。其優勢在於加快系統穩定速度、降低過衝幅度,並提升對干擾的耐受性,特別適用於對「精度」與「反應速度」要求極高的應用場域。
