# How to simulate bidirectional opto-isolators in Proteus?

I am making a circuit that uses the H11AA1 (http://www.vishay.com/docs/83608/h11aa1.pdf). This is a bidirectional opto-isolator.

I want to simulate it in Proteus, but in the libraries there are only uni-directional opto-isolators. ¿How can I simulate this device, or something similar?

I am suppose to have something like this:
