Application Notes
1、All relays are shipped in the “closed” position. It is possible that during transit or final assembly, the relay could change its state to the “open” position. Therefore, it is recommended that all relays be set to the desired state of the relay via a power supply.
2、In order to maintain an “open” or “closed” state of the relay, the coil voltage should reach the rated voltage. The pulse width should be 5 times the operating time to ensure a proper change of state. Do not energize both T1, T,2 and T3 at the same time on a dual coil, or energize the coil for longer than 1 minute (damage to the coil could incur).
3、Relays have polarity; if the user’s need is different fromthe information, please contact us.
4、The relay to the factory inspection and use should be handled to prevent damage to the factory for damaging the goods, shoud be strict distinction between the normal product and must not be used.
