>>>>>型号:IS220PDIOH1B 分立式输入/输出 模块/电池组之一
【功能描述】
什么是IS220PDIOH1B模型？
IS220PDIOH1B模型是离散输入/输出（I/O）模块或电池组。它与ISx0yTDBS2A/TDBSH8A或ISx0yTDBTH2A/TDBTH8A一起使用。
与ISx0yTDBS_8A/TDBT_8A附件板相比，PDIOH1A上使用的标准IS200TDBT/TDBS板之间有什么区别？
两种模型之间没有极端差异。这些端子板都用于危险应用，并被标记为带有实体参数的本质安全设备。使用两个端子板的危险场所略有不同，但功能相同。
IS220PDIOH1B模型可以在哪些危险场所使用？
IS220PDIOH1B型号可用于I类2区A/B/C/D组、I类2区IIC组和ATEX 2区IIC组。有关所有认证标准，请参阅完整的GEH-6725手册了解所有标准。
产品描述
IS220PDIOH1B单元是通用电气Speedtronic Mark VI/VIe/VIeS燃气轮机控制模块的离散I/O组的一部分，其附件组合经批准可用于危险场所。当IS220PDIOH1B型号在所选系统中运行时，它与多个端子板一起使用;使用的一些端子板标记如下：
ISx0yTDBSH2A
ISx0yTDBSH8A
ISx0yTDBTH2A
ISx0yTDBTH8A
这些端子板扩展了PDIO包的功能，因为以前的PDIO包只能与两个附件端子板一起使用。端子板标记为本质安全设备继电器触点端子板。
该装置包含两个以太网端口、一个本地处理器和一个数据采集板，用于GE Mark VI Speedtronic系列。2004年推出的Mark VIe I/O包的电子技术已经过时。IS220PDIOH1B的前面板包括用于设备电源的以太网端口和“attn”LED的LED指示灯。其他LED与继电器连接有关。
IS220PDIOH1B的最小额定电压为27.4 VDC，而标称额定值为28.0 VDC。该装置及其相关的端子板具有必须遵循的特定现场接线连接说明，包括电线尺寸和螺钉扭矩。

【英文介绍】
IS220PDIOH1A is an I/O package module for Mark VIe Speedtronic systems. Mark VIe was one of the later systems released by General Electric under the name Speedtronic. Speedtronic systems have been used for industrial turbine control since the release of the Mark I by General Electric in the late 1960s.
The IS220PDIOH1A has two Ethernet ports and its own native processor. It can be used with the terminal boards IS200TDBSH2A and IS200TDBTH2A. These I/O package/terminal board combinations have been approved for use in hazardous locations.
The minimum rated voltage of the IS220P DioH1A is 27.4 VDC. Its rating is 28.0 VDC. The device and its associated terminal boards have specific field wiring connection instructions that must be followed, including wire size and screw torque. This information can be found in the GE manual associated with the unit, such as the GEH-6725.
The front panel of the IS220PDIOH1A includes LED indicators for the two Ethernet ports, power indicators for the device, and the "attn" LED. Other leds are related to relay connections.
