Application Notes

Dual Coil – Positive Polarity: Place a negative connection on T2. Then apply a 50ms positive pulse to T1 to open the contacts or

to T3 to close the contacts.

Dual Coil – Negative Polarity: Place a positive connection on T2. Then apply a 50ms negative pulse to T3 to open the contacts or

to T1 to close the contacts.

Single Coil: Place a negative connection on T1. Then apply a 50ms positive pulse to T3 to close the contacts. Reversing polarity will open

the contacts.

Additional Application Notes

1: It is possible that during transit or final assembly the relay could change state. Therefore, it is recommended that all relays be set to

the desired state 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 50ms minimum to ensure a proper change of state. DO NOT energize both T1 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 without flex-wire cannot be tin-soldered. Moving or bending the terminals could cause damage to the internal structure of

the relay.
