大型雙LED顯示器顯示設定點和測得的溫度值
斜坡和浸泡功能，多達56個可編程段
選擇的反向或直接控制加熱或冷卻
程序設置報警點跟蹤過程
這種自動調整的臺式控制器監(jiān)視過程溫度和設定點值，同時在兩個大型LED顯示屏。自動調整功能將自動調整比例帶，速率，并復位，一旦你進入了一個設定點。該控制器可以手動設置自定義控制。對于更復雜的過程，斜坡和浸泡功能提供*多56離散可編程分部。該控制器還具有輸入，輸出和報警條件的狀態(tài)指示燈，分別指示，可編程報警，圖案的優(yōu)異功能，讓無盡的程序運行，和一個SPDT繼電器連接到音量可調聲音報警，
內置的安全系統(tǒng)。保護從意外或未經的更改的設定點和報警值。非易失性存儲器保留的參數(shù)在電源故障。控制器的編程和遠程監(jiān)控，可以通過內置的RS-485端口，接受MODBUS ASCII / RTU通訊協(xié)議。輕松連接任何USB功能的電腦，訂購可選的RS-485，USB轉換器。包含： 5英尺電源線

Autotuning Benchtop Temperature Controller; Universal Input; 100-240V
Large dual-LED display—monitor set point and measured temperature values simultaneously
Ramp and soak features up to 56 programmable segments
Select reverse or direct control for heating or cooling
Program alarm set point to track the process
This autotuning benchtop controller monitors process temperature and set point values simultaneously on two large LED displays. The autotuning feature will automatically adjust the proportional band, rate, and reset once you have entered a set point. The controller can be manually set for customized control. For more complex processes the ramp and soak function provides for up to 56 discrete programmable segments. The controller also features universal input, status lights that indicate output and alarm conditions, programmable alarms, pattern end functions that allow for endless program runs, and a SPDT relay that is connected to an audible alarm with adjustable volume.
The built-in security system protects set point and alarm values from accidental or unauthorized changes. Nonvolatile memory retains parameters during power failures. Programming and remote monitoring of the controller can be done through the built-in RS-485 port that accepts MODBUS® ASCII/RTU communication protocol. Connect easily to any USB capable computer, by ordering the optional RS-485 to USB converter.
