We are designing a new masking system and I have a quick question. Most projection systems have a control output signal with respect to a format change. What voltage is the most common for this signal?

Thank you in advance,

Andrew

Usually masking system use a dry contact from either the turret or the automation to pulse a masking change. The ADC motors are typically 24vac control
