9905-886 超速保护器件 通电跳闸
【产品详情】
型号 9905-886 三个单元以三分之二的投票配置封闭和连接。通电跳闸、24V 直流输入、可锁定外壳、跳闸警报和 LED。
这款伍德沃德制造的超速保护器件每 5 ms 对原动机速度进行采样，以监控超速情况。如果满足条件，则激活脱扣继电器。总响应时间保持在 40 毫秒或以下。9905-886 型是 220 Vac（A、B 和 C 单元各有自己的电源），通电跳闸版本。由于这是一种通电跳闸模型，因此如果输入功率丢失，插入继电器将不会启动。
该型号在 0 °C 下工作时的精度等级为 1.25%，但可以处理 –25 至 +65 °C（–13 至 +149 °F）的工作温度范围。 ProTech 203 型号 9905-886 必须安装在提供足够通风以冷却硬件的位置。此设备还需要防止阳光直射、潮湿、振动和可能引起电磁干扰的设备。
在安装型号 203-85191 之前，应查看伍德沃德 ProTech 9905 超速保护系统手册 886（B 版）。
该系统使用三个独立的速度传感单元来监控原动机速度。所有这三个单元都保存在同一个外壳中， 当使用可选的不锈钢轮毂时，符合NEMA 4X标准。
9905-886 型具有 LED 指示灯和报警输出（每个单元单独设置），用于发出错误警报，例如：
MPU 信号丢失
跳闸单元
中央处理器故障

【英文介绍】
Model 9905-886 Three units are enclosed and connected in a two-thirds voting configuration. Power trip, 24V DC input, lockable housing, trip alarm and LED.
This Woodward-built overspeed protection device samples the prime mover speed every 5 ms to monitor overspeed. If the conditions are met, the trip relay is activated. The overall response time is kept at or below 40 milliseconds. The Model 9905-886 is A 220 Vac (units A, B and C each have their own power supply), powered trip version. Since this is a power-on trip model, the plugged relay will not start if the input power is lost.
This model has an accuracy class of 1.25% when operating at 0 °C, but can handle an operating temperature range of -25 to +65 °C (-13 to +149 °F). ProTech 203 Model 9905-886 must be installed in a location that provides adequate ventilation to cool the hardware. This device also needs to be protected from direct sunlight, moisture, vibration, and devices that may cause electromagnetic interference.
Before installing Model 203-85191, review the Woodward ProTech 9905 Overspeed Protection System Manual 886 (B).
The system uses three independent speed sensing units to monitor the prime mover speed. All three units are kept in the same housing and comply with NEMA 4X standards when using optional stainless steel wheels.
Model 9905-886 has LED indicators and alarm outputs (each unit set separately) for false alarms, such as:
The MPU signal is lost
Trip unit
CPU failure
