Brahma 18049430 BT2310 control box

Brahma BT2310 (art. 18049430) is a microprocessor-based controller (“burner management unit”) that provides complete automation and safety for combustion systems. The device is designed for gas, oil and combination burners operating in intermittent (cyclic) mode. Thanks to its flexible settings, the controller works equally effectively with both single‑stage and two‑stage forced‑draught burners. Key feature: 24 V DC power supply The BT2310 (18049430) operates on 24 V direct current. This key difference from standard 230 V AC units makes it indispensable in systems with low‑voltage control circuits, as well as for directly restoring functionality to older equipment. Flexible flame detection The controller supports several flame detection methods, ensuring compatibility with any burner type: Ionisation – Based on the rectifying properties of the flame (standard for gas). UV sensor – Based on the ultraviolet radiation of the flame. Photocell – Based on visible light (for liquid fuel). Multi‑level safety system Safety is the highest priority in the design of the BT2310. The device includes the following protection mechanisms: Hardware lockout with manual reset – In the event of a fault (e.g., ignition failure), the unit goes into a safe state. To restart, the reset button must be pressed manually after the cause has been eliminated, eliminating the risk of unintentional burner start‑up. Two independent safety contacts – For controlling the fuel valves, guaranteeing reliable fuel shut‑off even if one component fails. Compliance with strict standards – Certification according to European standards EN298:2003, EN676:2003, DIN 4788 and EN230:2005 confirms full compliance with safety requirements for gas and oil equipment.

Important: The BT2310 24 V DC model (art. 18049430) should not be confused with the BT2310 12 V DC (art. 18049400) or the BT2310 230 V (18049401). Before purchasing, always check that the voltage and timing parameters match your burner’s settings. Accessories – A Microflat‑type base (socket) is required for connection (e.g., art. 16023008), purchased separately. The connection diagram is printed on the device housing. Installation and operation Mounting – The device can be mounted in any position in a dry, moisture‑protected location. To achieve the stated IP40 protection, a suitable base must be used. Wiring – Before connecting, strictly observe polarity and the 24 V DC voltage level. Incorrect connection to 220 V AC will immediately damage the unit. Lockout reset – Find and eliminate the cause of the fault (e.g., lack of fuel, dirty sensor), then press the Reset button on the housing. Maintenance – It is recommended to periodically check the integrity of contacts, wiring, and the cleanliness and proper functioning of the flame sensor(s). Advantages over alternatives High reliability – Electronic components are rated for more than 250,000 cycles, guaranteeing a long service life. Versatility – Suitable for burners of any type and fuel, as well as for single‑stage and two‑stage operation. Remote control – Possibility to connect remote lockout and reset signals, plus LED indication for convenient diagnostics. Compliance with international safety standards – EN 298, EN 676, EN 230, DIN 4788. Package contents Brahma BT2310 24 V DC burner control unit (art. 18049430) – 1 pc. Quick installation and operation guide (several languages). Note: The connection base, flame sensors and cables are purchased separately.
