注意事项 Application Notes

 

1. 所有继电器在出厂时都设为闭合状态。在装运或组装的过程中继电器可能会变成释放的状态。因而使用时(电源接入时)请根据需要重新将其设置为复归状态。

2. 为了使继电器保持在吸合或释放的状态,线圈电压需达到额定电压,为确保磁保持继电器动作或复归脉冲宽度小于50ms。不要向线圈上的Pin1和Pin2施加电压超过一分钟以上,以防线圈损坏。

3. 继电器有极性区分,用户需指明属于何种极性。

4. 继电器入厂检验及使用轻拿轻放,防止损坏影响参数,入厂做破坏性检查的产品要与正常产品严格区分标识,不得装机使用。

5. 非带铜绞线的继电器,负载引脚不能焊锡,引脚针刚性固定,不能随意扭动。

 

1. All the relays are shipped in the "operate" position because it is possible that during transit or final assembly the relay could change its state to the "release" position. please reset the relay into "operate" state when put in circuit according to need.

2. In order to maintain "operate" or "release" state of the relay, the coil voltage should reach the rated voltage. The pulse width should be 60ms or longer to ensure a proper change of state. Do not enegize both Pin1 and Pin2 at the same time on the coil for longer than 1 min (damage to the coil).

3. Relays are classified according to the polarity, if client need different form from information, please contact us.

4. The relay into the factory for destructive inspection should be protected from damage and strict distinction between the normal products.

5. Now with braided line relay, the load pin can not solder, not arbitrarily wrenched, two pins and righid fixation.
