Brahma CE11FO / CE31FO Control Units — Compact Safety Controllers for Atmospheric Gas Burners
Brahma CE11FO and CE31FO are microprocessor-based burner control boxes designed for intermittent operation of atmospheric gas burners. They handle ignition, flame monitoring, and safety shutoff in case of flame failure. These units are part of the Brahma electronic control series known for reliability and compliance with European safety regulations for heating equipment.
Application and Compatibility
The CE11FO / CE31FO series is suitable for:
- Atmospheric burners with or without a fan
- Heating boilers and water heaters
- Hot air generators and ovens
- OEM systems requiring compact and reliable control
The product line includes versions with volatile lockout (CE) and non-volatile lockout (CM), allowing adaptation to safety requirements — either automatic or manual reset.
Main Specifications
| Power supply | 230 V, 50–60 Hz |
| Flame detection | Ionization |
| Safety time (TS) | 3 or 10 seconds |
| Power consumption | 15 VA max |
| Protection rating | IP00 (for cabinet installation) |
| Operating temperature | -10 to +60 °C |
| Connector type | Multipin (Brahma standard) |
The modules feature an integrated EMC filter, 4 kV optical isolation, and built-in self-diagnosis. These ensure noise immunity and stable performance even under harsh conditions.
Functions and Operation
The CE units perform:
- Optional pre-purge and fan monitoring
- Ignition transformer activation
- Ionization flame sensing
- Shutoff if flame is not detected within TS
- LED indicators for operating state and lockout
The CE31FO version supports dual-stage operation (main + auxiliary output), making it suitable for multistage burners and systems with separate gas valves.
Wiring and System Integration
Wiring is done via Brahma-standard multipin connectors. The control unit interfaces with ignition transformer, solenoid valves, power supply, and ionization electrode.
Optional connections include pressure switches, fan relays, and limit thermostats, making it suitable for use in semi-automatic and automatic combustion systems.
Benefits of CE11FO / CE31FO
- Complies with EN 298 and EN 60730
- Broad compatibility with burner types
- Variants with automatic or manual reset
- Fast and reliable flame detection
- Low power consumption
- Compatible with Brahma and third-party ignition systems
