GE V7769-SDK-LNX-B数字量输入卡件
1.产 品 资 料 介 绍：
中文资料：
GE V7769-SDK-LNX-B使用此功能时，起动机状态开关输入必须来自通用控制
触点或并联组合的辅助“a”触点或串联组合的辅助
“b”触点来自降压接触器和全电压接触器。一次转换
469假设电机仍在GE V7769 SDK LNX Bleast下运行2秒。这样可以防止
GE V7769-SDK-LNX-B在开路过渡期间，如果电机电流变为零，则不会识别额外启动。
设定值第3页已指定为数字输入页面。469有九个数字输入。
GE V7769-SDK-LNX-B数字输入中的五个已预先分配为具有特定功能的开关。五个中的四个
预先分配的数字输入始终起作用，并且没有任何与

第五个，启动器状态，可以配置为“a”或“b”辅助触点。剩下的四个
数字输入是可分配的；也就是说，输入所用于的功能可以从
不同功能的数量。其中一些功能非常具体，其他功能可能经过编程以适应
符合用户要求。如果启用双速电机功能，ASSIGNABLE INPUT 4（可分配输入4）将专用

英文资料：
GE V7769-SDK-LNX-B this feature is used, the Starter Status Switch input must be either from a common control contact or a parallel combination of Auxiliary ‘a’ contacts or a series combination of Auxiliary ‘b’ contacts from the reduced voltage contactor and the full voltage contactor. Once transition is initiated, the 469 assumes the motor is still running for at GE V7769-SDK-LNX-Bleast 2 seconds. This prevents the GE V7769-SDK-LNX-B from recognizing an additional start if motor current goes to zero during an open transition.
Setpoints page 3 has been designated the DIGITAL INPUTS page. The 469 has nine digital inputs. Five of the GE V7769-SDK-LNX-B digital inputs have been pre-assigned as switches having a specific function. Four of the five pre-assigned digital inputs are always functional and do not have any setpoint messages associated with them.GE V7769-SDK-LNX-B
The fifth, Starter Status, may be configured for either an 'a' or 'b' auxiliary contact. The remaining four digital inputs are assignable; that is to say, the function that the input is used for may be chosen from one of a number of different functions. Some of those functions are very specific, others may be programmed to adapt to the user requirements. If the Two-Speed Motor feature is enabled, ASSIGNABLE INPUT 4 will be dedicated as the Two-Speed Motor Monitor.GE V7769-SDK-LNX-B
