The Selectra Maxitrol SC30 Series converts a controller’s DC output signal of 0-10 volts to a 0-20 VDC signal to provide compatibility with Maxitrol’s M/MR Series gas valves. Controls the normally open relay used to switch inducer speed and gas valve stage. Closes or opens the relay based on the controller’s DC output to the SC30. Also, provides an adjustable timer SC30 (0-30 sec) or fixed time, SC30-XXX: specified in 15-second increments (beginning with 45 seconds - 045) and adjustable VDC (5-15 VDC) output to the modulating gas valve on startup (powering of SC30). The feature eliminates problems associated with lighting the burner at its lowest gas input.
