IS220PDIOH1B單元是通用電氣Speedtronic Mark VI/VIe/VIeS燃氣輪機控制模塊的離散I/O包部分，附件組合批準用于危險場所。當IS220PDIOH1B型號在所選系統中工作時，它與多個端子板一起使用;所使用的一些端子板的標簽如下:

ISx0yTDBSH2A
ISx0yTDBSH8A
ISx0yTDBTH2A
ISx0yTDBTH8A
這些終端板擴展了PDIO包的功能，因為以前的PDIO包只能與兩個附件終端板一起工作。端子板被標記為本質安全裝置繼電器觸點端子板。

該單元包含兩個以太網端口，一個本地處理器和一個數據采集板，用于GE Mark VI Speedtronic系列。2004年推出的Mark VIe I/O包的電子技術已經過時了。IS220PDIOH1B的前面板包括用于設備電源的兩個以太網端口的LED指示燈和一個“attn”LED。額外的led與繼電器連接有關。

IS220PDIOH1B的最小額定電壓為27.4 VDC，而標稱額定電壓為28.0 VDC。該裝置及其相關端子板有必須遵循的特定現場接線連接說明，包括電線尺寸和螺釘扭矩。

在IS220PDIOH1B上使用TDBS或TDBT板時，有24個現場端子。所有的正極都被標記為接觸潤濕輸入。模型上的每個端子在負極和正極之間都是不同的。有關終端的更多信息，請參閱上述數據表的最后一頁。

IS220PDIOH1B

The IS220PDIOH1B unit is part of the discrete I/O package of the GE Speedtronic Mark VI/VIe/VIeS gas turbine control module with an accessory combination approved for use in hazardous sites. When the IS220P DioH1B model works in the selected system, it is used with multiple terminal boards; Some of the terminal boards used are labeled as follows:

ISx0yTDBSH2A
ISx0yTDBSH8A
ISx0yTDBTH2A
ISx0yTDBTH8A
These end boards extend the functionality of the PDIO package, as the previous PDIO package could only work with two attachment end boards. The terminal board is labeled as an intrinsic safety device relay contact terminal board.

The unit contains two Ethernet ports, a local processor and a data acquisition board for the GE Mark VI Speedtronic series. The electronics of the Mark VIe I/O bag, introduced in 2004, are outdated. The front panel of the IS220PDIOH1B includes LED indicators for two Ethernet ports for device power and an “attn” LED. Additional leds are associated with relay connections.

The minimum rated voltage of the IS220PDIOH1B is 27.4 VDC, while the nominal rated voltage is 28.0 VDC. The device and its associated terminal boards have field-specific wiring connection instructions that must be followed, including wire size and screw torque.

When using TDBS or TDBT board on IS220PH1B, there are 24 field terminals. All positives are labeled with contact wetting inputs. Each terminal on the model is different between the negative and positive terminals. For more information about the terminal, see the last page of the data table above.
