SSR-40 DA Solid State Relay

I recently purchased a SSR-40 DA Solid State Relay which I am having difficulties with.
I have a 24v AC input connected through a bridge rectifier to convert the input to DC. This seems to be operating okay as the LED on the SSR switches on and off accordingly.
For some reason. I cannot get the switch contact to close with a 240v AC supply which is only switching two 240v to 24v transformers.
Please advise.
