    Simulink's relay block is a little different from visSim's relay. If you apply the existing Simulink translator to a simple diagram: sine->relay->plot, you'll get the attached file. The differences are that Simulink lets you set the upper and lower values of the relay. VisSim is fixed at +1/-1. VisSim provides a zero value output when in a symmetric deadband zone, Simulink simply has a turn on value and turn off value. The trick to get similar results from both is to choose turn on and turn off values that fit into the symmetric band of VisSim's relay.
