ROSEMOUNT信號轉(zhuǎn)換器333 HART系列技術參數(shù)
SPECIFICATIONS | |
Functional Specifications | |
Service | Accessory product for the Model 3095 MV and Model 3244MV. |
Output | One, two, or three 4–20 mA output signals, user-selectable for DP, AP, GP, PT, or flow. |
Power Supply | External power supply required for each channel. Channel 1 must be powered for Tri-Loop operation. Each channel operates on terminal voltage of 11–42.4 V dc. |
Turn-on Time | Analog signals will be within specifications five seconds after power is applied to Tri-Loop. |
Installation Locations | Approved for FM ordinary locations. |
Temperature Limits | Ambient: 50 to 104 °F (10 to 40 °C). |
Humidity Limits | 0–95% non-condensing relative humidity. |
Failure Mode Alarm | If Tri-Loop diagnostics detect a transmitter malfunction or a Tri-Loop failure, the analog signal will be driven either below 3.75 mA or above 21.75 mA to alert the user. The high or low alarm signal is selectable by the Tri-Loop Model Number. |
Performance Specifications | |
Reference Accuracy | ±0.045% of span. |
Ambient Temperature Effect per 50 °F (28 °C) | ±0.15% of span. |
Stability | ±0.1% of span for 12 months. |
Analog Output Update | Tri-Loop responds to every HART burst update. (Typical transmitter burst update rate: 0.3 to 0.5 s.) |
Tri-Loop Response Time (after each burst update) | Channel 1–120 ms; Channel 2–220 ms; Channel 3–320 ms. |
Total Response Time | Typical response time from sensor change to transmitter to Tri-Loop analog update: 0.7 to 1.0 s. |
Physical Specifications | |
Electrical Connections | Screw clamps. Accepts 24-12 AWG solid or stranded wire. |
Dimensions | 1.57 3 3.11 3 3.36 in. (40 3 79 3 85,5 mm) |
DIN Rail Mounting Options | Asymmetrical 32mm G rail, symmetrical 35 3 7.5 mm top hat rail, or symmetrical 35 3 15 mm top hat rail. |
Weight | 0.27 lb (0,12 kg) |
ROSEMOUNT信號轉(zhuǎn)換器333 HART系列介紹
利用333 HART 三環(huán)信號轉(zhuǎn)換器，可以輕松獲得三個額外的模擬輸出。該信號轉(zhuǎn)換器旨在將數(shù)字 HART 多變量信號轉(zhuǎn)換為三個獨立的 4-20 mA 模擬過程變量，無需額外的變送器和接線。該產(chǎn)品可用作高警報或低警報設備，還提供 DIN 導軌安裝選項和電隔離模擬輸出通道，以實現(xiàn)靈活的配置。
With the Rosemount 333 HART Tri-Loop Signal Converter, you can easily obtain up to three additional analog outputs. This signal converter is designed to convert a digital HART multivariable signal into three independent 4-20 mA analog process variables without additional transmitters and wiring. Available as a high-alarm or low-alarm device, this product also offers DIN rail mount options and electrically isolated analog output channels for flexible configurations.
