Fireye Micro M Series Programmer Modules – MEPXXX

Applications & Benefits

The Fireye MicroM Programmer Modules determine burner operating sequences, trial-for-ignition (TFI) timing, purge cycles, and recycle/non-recycle functions within the MicroM flame safeguard system. They offer a wide range of options for relight, interrupted or intermittent pilot operation, flame stabilization, and post-purge control. These modules ensure flexible burner management and compliance with safety standards across many industrial applications.
