Hello,

Wich version of the relais are you planning to use?
You must use a protection diode, cathode to the + and anode to the transistor, to protect the transistor from the back EMF of the relais.

Hello,

Do you want to use the standard or high sensitivity relais?
What voltage is the relais?

The standard relais uses 100mA at 5 Volts.
The TLP can switch 150 mA absolute maximum.

PS I have attached the both datasheets.
