Selectra Series SC30 is designed for Indirect Fire Gas Applications Using 2-speed Inducers and 2-stage Gas Valves.

The track mounted SC30 Series controls three functions:
  • 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 controller's DC output to the SC30.
  • Provides an adjustable timer SC30 (0-30 sec) or fixed time, specified in 15 second increments (beginning with 45 seconds - and adjustable VDC (5-15 VDC) output to the modulating gas valve on start-up (powering of SC30).
    Note: The feature eliminates problems associated with lighting the burner at its lowest gas input.
