Triac Output requirements.

Issue

Unable to control field device with a Triac output.

Product Line

Andover Continuum

Environment

  • b3
  • i2

Cause

  • Triac outputs cannot switch DC loads.
  • Triac outputs require a minimum 30 mA load in order to switch. 

Resolution

If the inductive load draws less than 30mA a resistor needs to be wired in series with the switched load.
