If it lies with in the range of 0.5A then you don't need to connect extra relay or some thing else. However if this rating is exceeded then u may either use a 24v dc relay to drive the contactor or can use darlington optocoupler which in turn will increase safety for your DO module.

If the coil consume more than the channel limit (in your case: 0.5A), you can use also DO relay module. examples for DO Relay modules: 6ES7322-1HH01-0AA0 & 6ES7322-1HF01-0AA0. Regards,
