9905-020 单独的执行器控制 WOODWARD

【产品详情】

伍德沃德的 9905-020 部件来自 2301A 负载分配和速度控制系列。由 20-40 Vdc 输入供电，是单独的执行器控制。

该装置是前向控制，低压型号，带有单独的执行器，不提供减速斜坡，该单元的执行器电流为0-200 mA。如果设备以 20-40 Vdc 的输入功率下降，则为该控制器供电时，必须与 IEC 标准授权的安全超低电压 （SELV） 电源一起使用。该型号要求工作温度在 -40 至 +185 华氏度范围内。

在这个二十九个终端模型上，当它涉及最小燃料接触时，控制端子二和三是控制最小燃料接触的东西，并且是该装置根据需要运行所必需的。最小燃油触点设计用于装置所连接的原动机的正常关闭。在任何情况下，都不应将最小燃油接触用作紧急停止机制。

由于9905-020控制是低压型号，连接屏蔽时端子<>必须打开以尽量减少燃油接触，关闭端子<>以覆盖故障速度信号，关闭端子<>以达到额定速度，如果使用怠速，请确保端子<>打开。在任何情况下使用控制器时，控制器都不应安装在原动机的发动机上。

操作控制器时，不应在任何其他大电流设备附近使用模型，因为这可能会导致干扰，从而影响控件的质量和性能。

【英文介绍】

Woodward's 9905-020 parts are from the 2301A load Distribution and speed control series. Powered by a 20-40 Vdc input, it is controlled by a separate actuator.

The unit is a forward-controlled, low-voltage model with a separate actuator that does not provide a deceleration ramp, and the unit's actuator current is 0-200 mA. If the device drops at an input power of 20-40 Vdc, power to this controller must be used in conjunction with a safe ultra-low voltage (SELV) power supply authorized by the IEC standard. This model requires an operating temperature range of -40 to +185 degrees Fahrenheit.

On this twenty-nine terminal model, when it involves minimum fuel contact, control terminals two and three are what control the minimum fuel contact and are necessary for the device to operate as required. The minimum fuel contact is designed for normal closing of the prime mover to which the device is connected. Under no circumstances should minimum fuel contact be used as an emergency stop mechanism.

Since the 9905-020 control is a low voltage model, the terminal <> must be opened to minimize fuel contact when connecting the shield, the terminal <> must be closed to override the fault speed signal, the terminal <> must be closed to reach the rated speed, if using idle, make sure the terminal <> is open. In any case when using the controller, the controller should not be mounted on the engine of the prime mover.

When operating the controller, the model should not be used near any other high-current device, as this can cause interference, which can affect the quality and performance of the control.
