PT100可配置溫度傳感器MINI MCR-SL-PT100-UI（-SP）（-NC）是一種可配置的3路隔離溫度測量傳感器。它適用于根據IEC 60751在2、3和4導體連接系統中連接PT100電阻溫度計。在輸出側，模擬標準信號0…20 mA、4…20 mA，0…10 V、0…5 V、1…5 V，10…0 V、20…0 mA、20…4 mA可用，電氣隔離。DIP開(kāi)關(guān)位于外殼側面，允許配置以下參數：–連接系統，–要測量的溫度范圍，–輸出信號，以及–錯誤評估類(lèi)型。電壓供應（19.2…30 V DC）可通過(guò)模塊的接線(xiàn)端子“7”/“8”連接，或通過(guò)DIN導軌連接器連接在一起（參見(jiàn)第8頁(yè)圖5）。請注意第9.1頁(yè)的“連接系統”輸入：PT100電阻溫度計2透明蓋3診斷LED 4 ZBF槽6 Zack標記條5輸出：標準信號6電源電壓7 DIN導軌連接器的連接選項8 DIP開(kāi)關(guān)S1 9 DIP開(kāi)關(guān)S2 10 DIP開(kāi)關(guān)S3 11 EN安裝導軌的通用按扣式腳踏診斷LED（圖1，詳圖3）在上可見(jiàn)并顯示以下錯誤狀態(tài)：–LED閃爍：測量范圍跨度小于50 K–LED亮起：傳感器側斷線(xiàn)–LED亮起來(lái)：傳感器側短路–LED亮了：測量范圍超出–LED亮著(zhù)：測量范圍低于如果設備未配置（“NC版本”：MINI MCR-SL-PT100-UI-NC或…-SP-NC），所有DIP開(kāi)關(guān)都位于位置0。在設置DIP開(kāi)關(guān)之前，設備沒(méi)有定義的功能。DIP開(kāi)關(guān)S1 DIP開(kāi)關(guān)S2（圖1，詳圖8）定義了連接系統、輸出信號范圍和測量范圍的開(kāi)始。
通過(guò)MINI模擬模塊供電
如果對齊的MINI模擬模塊的總電流消耗不超過(guò)400 mA，則可以直接在MINI模件的接線(xiàn)端子處饋電。我們建議上游連接400 mA保險絲。使用電源接線(xiàn)板供電電源接線(xiàn)板MINI MCR-SL-PTB（訂單號：28 64 13 4）或MINI MCR-SL-PTB-SP（訂單號為28 64 14 7），形狀相同，用于將電源電壓饋送至DIN導軌連接器。我們建議上游連接2 a保險絲。使用系統電源裝置饋電系統電源裝置MINI-SYS-PS-…（訂單號：28 66 98 3），1.5 a輸出電流與DIN導軌連接器接觸，電源電壓允許從網(wǎng)絡(luò )中提供多個(gè)MINI模擬模塊。2-導線(xiàn)連接系統（圖6）-對于短距離（<10 m）-電纜電阻RL1和RL2直接包含在測量結果中，并相應地偽造結果。3導體連接系統（圖7）-對于PT100傳感器和MINI模擬模塊之間的長(cháng)距離連接，所有電纜電阻值必須完全相同，以平衡傳感器電纜電阻（RL1=RL2=RL3）。4導體連接系統（圖8）–適用于PT100傳感器和MINI模擬模塊之間的長(cháng)距離連接以及不同的電纜電阻（RL1≠ 第二輪≠ 第三輪≠ RL4）。
Configurable Temperature Transducer for PT100
MINI MCR-SL-PT100-UI(-SP)(-NC) is a configurable 3-way isolated temperature measuring transducer. It is suitable for the connection of PT100 resistance thermometers in acc. with IEC 60751 in 2, 3 and 4-conductor connection systems. On the output side, the analog standard signals 0...20 mA, 4...20 mA, 0...10 V, 0...5 V, 1...5 V, 10...0 V, 20...0 mA, 20...4 mA are available, electrically isolated. The DIP switches are accessible on the side of the housing and allow the following parameters to be configured: – Connection system, – Temperature span to be measured, – Output signal, and – Type of error evaluation. The voltage supply (19.2...30 V DC) can be provided via connecting terminal blocks "7"/"8" of the modules, or together, via the DIN rail connector (see Figure 5 on page 8). Please also observe "Connection Systems" on page 9.1 Input: PT100 resistance thermometer 2 Transparent cover 3 Diagnostics LED 4 Groove for ZBF 6 Zack marker strip 5 Output: Standard signals 6 Supply voltage 7 Connection option for DIN rail connector 8 DIP switch S1 9 DIP switch S2 10 DIP switch S3 11 Universal snap-on foot for EN mounting rails Diagnostics LED (Figure 1, detail 3) is visible on the front and displays the following error statuses: – LED flashes: Measuring range span less than 50 K – LED lit: Line break on the sensor side – LED lit: Short circuit on the sensor side – LED lit: Measuring range exceeded – LED lit: Measuring range fallen below If the device is not configured ("NC version": MINI MCR-SL-PT100-UI-NC or ...-SP-NC), all DIP switches are at pos. 0. The device does not have a defined function until the DIP switches have been set. DIP Switch S1 DIP switch S1 (Figure 1, detail 8) defines the connection system, output signal range and the start of the measuring range.
Feeding in power via the MINI Analog module
Where the total current consumption of the aligned MINI Analog modules does not exceed 400 mA, the power can be fed in directly at the connecting terminal blocks of a MINI Analog module. We recommend connecting a 400 mA fuse upstream. Feeding in power with a power terminal block Power terminal block MINI MCR-SL-PTB (Order No.: 28 64 13 4) or MINI MCR-SL-PTB-SP (Order No.: 28 64 14 7), of the same shape, is used to feed in the supply voltage to the DIN rail connector. We recommend connecting a 2 A fuse upstream. Feeding in the power with a system power supply unit System power supply unit MINI-SYS-PS-... (Order No.: 28 66 98 3) with 1.5 A output current contacts the DIN rail connector with the supply voltage, allowing several MINI Analog modules to be supplied from the network.2-conductor connection system (Figure 6) – For short distances (< 10 m) – Cable resistances RL1 and RL2 are incorporated in the measurement result directly and falsify the result accordingly.3-conductor connection system (Figure 7) – For long distances between PT100 sensor and MINI Analog module – The value of all cable resistances must be exactly the same in order to balance out the sensor cable resistances (RL1 = RL2 = RL3).4-conductor connection system (Figure 8) – For long distances between the PT100 sensor and the MINI Analog module and different cable resistances (RL1 ≠ RL2 ≠ RL3 ≠ RL4).
