3BHE021951R1024 模块终端单元

【产品详情】

模块终端单元（MTU）将模块总线分配给I/O模块 以及下一个MTU。

I/O模块具有开放式通风塑料外壳。在所有I/O的前端模块至少有三个发光二极管(故障、运行和警告)指示模块状态。此外，一些模块有指示OSP或主要参见表3和表4。在完全运行的I/O站中，可以更换I/O模块。机械键控 on模块和MTU防止I/O模块入以下位置，它们可能会被过高的电压或电流损坏。电子打字每个模块中的标识ID防止输入/输出模块被带入如果模块的ID与配置的不匹配，则由ModuleBus主机进行操作模块类型定义。有单个模块和冗余模块应用程序。

电流输入能够处理变送器电源的短路，而不会损坏。输入耐受HART通信。标称输入范围为：0（4）...+20毫安，0（2）...+10 V。AI815模拟输入模块，0..20毫安，0..5V，HART AI815模拟输入模块有8路模拟输入。可以对输入进行配置电压或电流。该模块具有HART直通功能。标称输入范围为：0（4）...+20毫安，0（1）...+5 V。AI820差分模拟输入模块，±20毫安，±10伏，±5伏 AI820差分模拟输入模块有4个差分、双极电流/电压输入。该模块适用于要求高共模抑制额定值和/或双极性电压或电流输入。

【英文介绍】

The module terminal Unit (MTU) allocates the module bus to the I/O module and the next MTU.

The I/O module has an open ventilated plastic housing. In all I/O front-end modules there are at least three leds (failure, running, and warning) indicating module status. In addition, some modules have indicated OSP or mainly refer to Tables 3 and 4. In a fully operational I/O station, the I/O module can be replaced. Mechanical keying on modules and MTU prevent I/O modules from entering the following locations where they can be damaged by too high a voltage or current. Electronic typing The identification ID in each module prevents input/output modules from being brought in if the module ID does not match the configured module type defined by the ModuleBus host. There are single module and redundant module applications.

The current input can handle short circuits in the transmitter power supply without damage. Input tolerates HART communication. Nominal input range: 0 (4)... +20 MA, 0 (2)... Plus 10 V. AI815 Analog Input module, 0... 20 mah, 0... 5V, HART AI815 Analog input module has 8 analog inputs. The input can be configured with voltage or current. The module has HART pass-through function. Nominal input range: 0 (4)... +20 MA, 0 (1)... Plus 5 V. AI820 Differential analog input module, ±20 MA, ±10 V, ±5 V The AI820 differential analog input module has four differential, bipolar current/voltage inputs. The module is suitable for applications requiring high common-mode rejection ratings and/or bipolar voltage or current inputs.
