Product Details

The Fireye PPC4000-230V is a cost-effective Nexus parallel positioning fuel-air ratio controller running on 230 VAC, designed for gas-fired and oil-fired industrial burners. This fuel air ratio controller delivers precise modulation control and works alongside Fireye flame safeguard units to maintain optimized fuel and air mixture, cutting fuel consumption and lowering exhaust emissions. As a reliable parallel positioning burner controller, it supports configurable combustion curves, high-precision servo positioning up to ±0.1°, and seamless connection with FX series servomotors via CANbus. This Nexus combustion modulation module accepts feedback signals from PXMS pressure transmitters and optional oxygen trim probes for continuous combustion trimming; it is widely deployed on small-to-medium steam boilers, hot water boilers and process heaters and stocked as genuine replacement spare part for Fireye Nexus combustion systems.

Supported Functions

This controller adjusts fuel and air actuator positions automatically following pre-calibrated combustion curves according to boiler load demand. It provides PID regulation for pressure or temperature, supports oxygen trim for excess oxygen correction, and integrates safety limit interlock logic. It enables remote reset, lockout alarm output, and parameter backup for fast commissioning and spare replacement. It also supports VFD fan speed control for smooth modulation across the full firing range.

Core Functions

The compact unit delivers stable, low-hysteresis positioning for economical burner retrofits. CANbus daisy-chain wiring reduces field wiring workload for multi-servo setups. It is programmed via Fireye configuration software and stores combustion profiles for quick restoration after part replacement, and it serves as direct drop‑in substitution for existing PPC4000-230V controllers.
