通用電氣 UR-4CH GE 通用繼電器模塊

概述
UR-4CH 數字 I/O 模塊 GE Multilin UR 系列通用繼電器，帶 4 個固態輸出

UR-4CH 數字 I/O 模塊屬于“4C”訂單規格。這數字 I/O 模塊具有 4 個固態 MOSFET 輸出（電流和可選電壓）。由于 UR-4CH 是固態輸出數字 I/O 模塊，這意味著它非常適合直接脫扣應用，因為它具有快速脫扣時間、快速復位時間和高電流分斷能力。這些輸出可用于控制和監控變電站輔助設備和其他用于保護應用的設備。通用繼電器 Multilin 中的數字 I/O 模塊的 4A 和 4B 訂購選項也有四個 MOSFET 輸出。三種訂貨代碼的區別在于 4A 選項缺少監控功能，而 4B 訂貨選項可以通過可選的電流監控來監控電壓。如前所述，4C 訂單選項可以監視電流，并根據特定單元監視電壓的附加選項。其他數字 I/O 模塊可能具有完全不同的特性（A 型或 C 型）或包含用于溫度監控功能的 RTD 輸入。UR 中包含的數字 I/O 特定于通用 Multilin 繼電器的最終功能和應用。。

Ur-4ch digital I / O module belongs to "4C" order specification. This specifies that the digital I / O module has four solid-state MOSFET outputs (current and optional voltage). Since ur-4ch is a solid-state output digital I / O module, it means that it is very suitable for direct tripping applications because of its fast tripping time, fast reset time and high current breaking capacity. These outputs can be used to control and monitor substation auxiliaries and other equipment for protection applications. The 4A and 4B ordering options for digital I / O modules in the universal relay Multilin also have four MOSFET outputs. The difference between the three ordering codes is that the 4A option lacks monitoring function, while the 4B ordering option can monitor the voltage through optional current monitoring. As mentioned earlier, the 4C order option can monitor the current and additional options for monitoring the voltage according to a specific unit. Other digital I / O modules may have completely different characteristics (type A or C) or contain RTD bs for temperature monitoring functions. The digital I / O contained in the ur is specific to the final function and application of the universal Multilin relay.
