Teensy 3.2 and Solid State Relay

Looking at an actual data sheet https://www.omega.com/manuals/manualpdf/M3813.pdf to find some numbers, in theory it should work. Key thing and missing from the docs is what current the thing draws from a 3.3V logic signal to turn on. The Imax of 15ma is pushing the limits of a teensy pretty hard, if it needs more than that at lower voltages to turn on then it's a problem.

Suggested step would be to wire it up as shown in the drawing but with direct supply from the Teensy 3.3V pin and measure the current needed to get it to run, and also confirm it really does close the contact at such a low voltage.
